Industrial thermal curtain: electric and water

Enterprises and buildings of industrial type, as well as residential buildings need to be protected from cold air coming in from outside. This problem becomes especially relevant in winter period the time when through the ever-opening doors leaves a large number of heat. To ensure a comfortable temperature and prevent heat loss in garages, hangars, warehouses and other industrial premises, an industrial thermal curtain is installed above the doorway.

Industrial water curtain

Principle of operation

On the various premises production type with large gates, raw materials or any goods are unloaded very often. In this regard, one has to deal with constant temperature fluctuations, which negatively affects products and raw materials, as well as the condition of people working in this place.

Besides. due to temperature fluctuations, you have to overpay for heating. And if it's about electrical system heating, then this case You will also have to pay large electricity bills.

The air thermal curtain is mounted on the site where goods are loaded and unloaded and does not allow cold air currents to penetrate into the room. The principle of operation of the device resembles the operation of a heat gun and is as follows: under the influence high pressure air is directed to the area of ​​the gate opening.

Depending on the model, on some devices, air masses are supplied from the street, on others they are heated. The air supply angle varies between 35°-40°. The thermal curtain on the gate to the workshop is simple and convenient to use, it does not create obstacles for the movement of personnel and the passage of loading machines.

There are two types of curtains:

1. Shibable. The set of such a device includes a heater responsible for heating the air that enters the curtain.
2. Mixing. Such devices take air from the street. They are mainly installed in technical rooms.

Varieties of industrial curtains

Between themselves, thermal curtains differ in their design features. Depending on a number of criteria, several types of industrial thermal curtains are distinguished.

Parameters on the basis of which air curtains are classified:

• operating mode;
• type of air mass intake;
• location.

Industrial thermal curtains for gates differ in the mode of operation. For example, curtains installed in warehouses. can function either permanently or for a certain period of time. For uninterrupted stable operation of curtains, it is necessary to carry out regular Maintenance. If we are talking about temporarily used air curtains, then such a device starts working only at the moment the gate is opened. Given these features, the device will be quite economical.

Automatic thermal curtain

But, on the other hand, industrial air curtains, which are constantly on, will play the role of a fairly efficient heating device. Very often they are used as a hood.

Another difference between industrial air curtains is in the air direction:

• the flow can spread from bottom to top - this is ensured by the gap, which is located below;
• air moves from above - in this case, the gap is above the opening;
• if the air flow is horizontal, then the slot is located on the side; often such devices are installed on wide openings.

Each type has its own advantages, which you need to pay attention to when choosing. For example, for wide, but low openings, curtains are more suitable, where air is supplied from below. Such devices do a very good job of distributing cold air across the floor. However, such structures have one significant drawback - they become clogged very quickly, so they need to be serviced regularly.

Industrial curtains, in which air is supplied from above, lose their effectiveness when they stop in the opening vehicles. Such designs do not delay the flow of cold air masses that pass under the machine. Considering this fact, side curtains are usually installed at industrial and production facilities.

Electric thermal curtain

Industrial curtains, which are placed above the opening, become ineffective when the opening is high.

According to the place of air intake, thermal curtains are divided into:

• devices with internal intake and heating, similar designs take air from a room that is isolated from the cold;
• without heating;
• with an external heated intake, in this case, the air is taken from the street;
• external fence, but without heating.

Some industrial air curtains can be used as a supply ventilation device or as auxiliary heating equipment.

Installation of an industrial curtain for gates

Electric industrial thermal curtains can be installed at absolutely any enterprise. The only drawback is the price of the device, because. such a design will consume a lot of electrical energy.

Depending on the location, curtains can be vertical and horizontal. If you decide to install a horizontal type structure, then you must take into account the length of the curtain and the width of the opening on which it will be installed. The height of the device must be no less than ¾ of the height of the window or door.

By following all these installation requirements, you will protect the room from cold air currents as much as possible.

Calculation

In order to select the most best option industrial thermal curtain for a warehouse, workshop or garage, some indicators should be taken into account:

1. The number of openings and the intensity of their operation (meaning how often they open).
2. Specify whether cars will stop in the openings.
3. The presence of an air conditioning system.

Based on these parameters, certain norms for heating the air at the opening and the temperature of the air curtain itself are set.

High pressure air curtain

Before purchasing a certain model of thermal industrial curtain, it is necessary to carry out an accurate calculation of the indicators of the system. They are identified based on the original data. In this way, you can increase the efficiency of energy consumption.

The main parameters to be considered when making the calculation:

• overall system performance, which is influenced by various factors;
• the speed at which the fan blows air;
• angle of inclination of the air flow;
• opening size;
• heater power;
• heat carrier power.

In order to calculate, there are several special techniques. Using any of them, you will get accurate results. It is necessary to carry out the calculation of an industrial curtain, since even minor inaccuracies in the indicators can affect a large loss of electrical energy.

The table below shows technical specifications air curtain based on the size range of models.

Design features

Each individual model of industrial air curtain is selected depending on its main purpose. For example, a lower curtain is well suited for installation on a garage car door. It is possible to adjust the direction of the incoming air by means of special slotted nozzles that are mounted on the device.

If the gate will be located in a room in which wagons often call in, then in this case, pay attention to vertical models, which are located on both sides of the opening. You can use both devices with a fan for two racks at once, as well as independent installations. Air intake can be carried out from different areas of the room.

Features of the structure of the thermal curtain

The curtain, which is placed horizontally and installed above the gate, is used when the air flow rate is not more than 38,000 m³/h. In the case when the air curtain is mounted on a high opening, it is better to use hot air, approximately 60 °C. In this way, you will ensure the maximum optimal temperature at the bottom of the opening.

Besides, Special attention it is worth giving the area of ​​​​the duct, which is responsible for the inflow fresh air. It is important to ensure a uniform pressure of air masses.

Automation

For more convenient control of industrial thermal curtains, special automation is attached to them.

This device is designed to solve several problems at once:

1. First of all, the automation starts and stops the operation of the fans during the opening and closing of the gate.
2. Responsible for changing the temperature of the air flow, taking into account how it changes temperature regime on the street and in the building.
3. Starts and stops the air curtain in case of a change in the temperature regime outside.

By installing automation on the gate, you can save a significant part of the funds due to the fact that a reasonable consumption of electrical energy will be ensured.

Choosing a thermal curtain for the garage

Often, motorists spend a lot of time in the garage. To ensure the most comfortable pastime without cold and dampness, a thermal curtain is installed. Choosing such
equipment in the garage, it is worth considering a number of characteristics:

• installation length (same as in the case of industrial premises, it must exceed the width of the door opening);
• power;
• type of heating elements;
• the presence of control elements (remote control, thermostat);
• installation type (horizontal or vertical);
• curtain type depending on the heat source (water or electric).

The most important parameter is the performance of the air curtain. It will depend on the air flow rate and maximum height on which the device can be installed.

Also pay attention to the turbine, which acts as a fan.

Typically, the turbine is placed in the center of the curtain, it forms the desired flow warm air. Curtain models with two turbines can be found on the market. The price of such units is lower, but they do not always meet the expectations of users. This is due to the fact that with curtains in which there are two fans located on the sides, the air flow to the heating elements may be uneven and there may be gaps in the center of the heated passage.

Most often, vertical electric thermal curtains are used for the garage. This is due to the fact that in such a design heating elements located inside metal case, will be located directly above the doorway or above the gate.

As a result, warm air will be directed straight down, forming a thermal protection inside the garage.

Vertical structures are easy to manage and install. In addition, by installing such a curtain, you will significantly reduce the cost of heating the garage and the room will be protected from the cold stream, even if the gate is open.

Thermal curtains for front door garage

Water thermal curtain is also popular. However, it is only suitable for those rooms where a central heating system is established.

Summing up, it should be noted that when choosing an industrial thermal curtain, one should pay attention to a number of factors: the intensity of the gate opening, the strength of the wind blowing on the street, the design features of the place where the device is located, as well as the presence of ventilation in the room.

Gates in workshops and warehouses are equipped with PVC curtains in order to ensure long-term storage of products, safe work of workers, and convenient movement. Silicone curtains allow you to achieve great benefits, because they found wide application in industry. Along with such canopies serve as an effective addition and directly replace the gate in the warm season.

You can order PVC curtains for gates right now in the "World of Curtains MSC" and find out the full cost using. But first, we offer you to get acquainted with all the advantages of these products, which have proven themselves on the market as the most practical and inexpensive way to solve many industrial and warehouse problems.

Advantages of PVC curtains for a warehouse

Thermal curtains are arranged above the gate. Silicone strips are arranged vertically tightly to one another. There are several ways to manufacture and install thermal curtains over the gate. The choice depends on the width, intensity and nature of the operation of the opening; climatic features.

The PVC curtain mounted on the gate can be reinforced with a special installation. In the "World of Curtains MSC" they order silicone curtains with protective coating from insects, ultraviolet, infrared lighting; to add durability. However, the main advantages that distinguish PVC curtains installed on the gate, we will consider further:

• . The curtains effectively maintain the temperature regime and the set humidity level, which makes it possible to conveniently store products of various types of consumption. Thanks to high density, PVC curtains on the gate effectively resist any drafts.
• Noise isolation. Mounted curtain on the warehouse gate when correct styling dampens noise well.

• Ease of maintenance. It is enough to wipe the curtains with a damp cloth to make them clean. No need to open and close manually.
• Application safety. The use of canopies meets the technical standards established for workshops and warehouses, as well as the rules of labor protection and safety. The plastic used is non-toxic and completely harmless to environment and human health.

Industrial curtains and curtains - it's economical!

Installing a PVC curtain on the gate can significantly reduce costs. Let's name the main points on which you can regularly save decent money by using silicone curtains.

25 June 2015 Alexei

The thermal curtain on the gate to the workshop belongs to the industrial type of equipment. But the main function of such a technique is similar to that implemented by other analogues - the creation of an air barrier to mix cold air from the street and warm air from the room.

There is quite big choice such devices, which allows you to install them on any side of the gate: on the side, above them, along the bottom.

What are they for and where can they be used?

Thermal curtain in manufacturing facility mounted in order to reduce heat loss in rooms where most time, doorways are not protected from the penetration of air from the street through them. This happens during loading / unloading, frequent entry of vehicles. But in addition to production facilities, such equipment is often installed privately - in garages. Another area of ​​application is civilian facilities, such as car repair shops.

Watch the video, how it works:

A thermal air curtain at the gate to the workshop allows significant energy savings, which is explained by the absence of the need for intensive heating of the room after each opening of the gate. However, the location also affects the effectiveness of such a technique.

For example, in a garage or car workshops, where a picture is often observed when vehicles stop directly in the opening itself, it is highly recommended to use the lower airflow option, since the upper supply of warm air simply will not block the flow of cold air due to the car standing in the opening.

What are the types of curtains, their design and features of work

Electric curtains

There are two types of equipment used today with a unidirectional supply of heated air:

• Industrial thermal air curtains for gates are shimmable - they have a heater, through which the device heats the air environment to a certain temperature value;
• Mixing - operate on the basis of the principle of outside air intake.

There is also a similar technique and the mode of operation: on a permanent or periodic basis. There is also a classification according to the direction of the supplied air flow:

1. The flow is from bottom to top. In this case, the devices are installed under the gate. As mentioned above, this method is not always effective, but only when cars often stop at the gate. However, this solution also has disadvantages - this is too fast clogging of the mechanism, which is why maintenance is required an order of magnitude more often.
2. Air movement from top to bottom. it classic way location of such equipment. The equipment is installed directly above the gate.
3. The directional flow moves in a horizontal plane, which is realized by placing devices on the side of the gate.

Other groups are also distinguished by design:

• Thermal air curtains for water gates - operate on the basis of an existing heating system or hot water supply, which basically allows you to warm up the air with the direct participation of the coolant;
• Electric - unlike the first option, they can be used almost everywhere if the facility has a dedicated power source for connecting it, while water installations are used where without fail must be heating system or hot tubing.

The principle of operation of such equipment is similar for all versions: air is pumped through a powerful fan built into the device case. His exit can be arranged different ways, it all depends on the type of installation. But in any case, the design will provide for a gap of a certain size through which air is supplied to the boundary of the object and the external environment.

A thermal air curtain for a garage or workshop is selected taking into account a number of parameters:

When diesel or gas is selected heat gun for a garage or a device for a workshop, in both cases it is important to correctly determine the thermal power of such equipment, which will allow heating the air at the required height and at a sufficient speed.

Watch the video, selection criteria:

When choosing a unit with required power it is necessary to take into account the volume of the room, as well as the level of its thermal insulation and the average value of the temperatures outside and inside the object.

How to calculate heat output and air flow

To calculate sufficient performance, it is necessary to approximately imagine how fast air enters a room of a certain volume. To do this, the value of the air flow rate and the volume of the room are multiplied. The resulting value (L pr) is used to obtain the value of the required air flow using the following technique:

Lhead \u003d Lpr / j (B / b + 1),

where j is a coefficient that determines the strength of the flow created by the device, corresponds to a value of 0.45;

B, b are the parameters of the slot through which the air flow will be supplied.

Calculation of the power of the thermal curtain on the gate:

Qstart = 0.24Lstart (tc - tstart),

where t c, t initial - the values ​​​​of the average temperatures directly air curtain and outdoor environment, respectively.

Features of installation and operation

Such equipment is installed as close to the opening as possible. This achieves the highest degree of efficiency in the organization of the protective air jet. It is also important to ensure that the length of the device corresponds to the width of the opening, if the installation option above the gate was chosen. In the case when a vertical installation is mounted, then it is necessary to select its length based on the height of the gate.

All work on the installation of such equipment is carried out exclusively with inside premises. Another important nuance– control of the operation of air conditioning and ventilation systems in order to avoid additional impact on the operation of the device. If the gate is too wide, then several installations can be used. Their connection to each other in this case is realized by means of a special connecting kit.

Watch the video, installation and installation:

Depending on the type of the selected device, the mechanism can be equipped with fastening elements: for wall or ceiling mounting. Management of such equipment is also carried out in accordance with the type of device. When installing a curtain, it is necessary to select anchors taking into account not only the main weight of the structure itself, but also the likely load in the event of vibration waves, which is especially important in repair shops and production shops.

Thus, the selection and installation of special equipment for creating air curtains is somewhat more complicated than buying equipment such as a diesel heat gun for a garage. Although before purchasing industrial device taken into account thermal power, air flow rate and performance. But to these parameters is added the need to choose the installation method (ceiling, wall, floor), assessment of the load on the fasteners and, of course, the dimensions of the equipment itself, which will create an air curtain across the entire width of the doorway or gate.

PVC strip curtains — effective method save desired temperature(heat or cold) indoors: PVC curtains are what you need for your warehouse, workshop, shop or production!

At many enterprises, the problem of energy saving arises due to constantly open doorways through which vehicles and personnel pass. It would be too inconvenient to equip openings with doors, especially since there is an excellent alternative - PVC curtains made of durable material.

Many enterprises and warehouse complexes are faced with the problem of maintaining a comfortable temperature inside production and storage facilities, shops.

With the constant opening of doors and gates for the passage of personnel or the passage of equipment, air is exchanged between the room and the street. AT winter time enters the room cold air and heaters "warm the street", and in summer heat The air conditioners are not up to the task.

PVC curtains for gates. Thermal curtains
PVC curtains for gates are the ideal solution for entrance gate. PVC curtains on the gate are installed for the gate to the workshop, for the gate of the warehouse and on Garage Doors. Silicone curtains on the gate are safe and resistant to loads when passing from small to oversized vehicles. PVC curtains for gates open only a part of the opening, according to the size of a passing person or a transported load. PVC curtains for gates do not require the driver to leave: the equipment simply passes through the PVC curtains, and the curtains on the gate almost instantly return to their original, vertical position and hermetically close the opening.

As practice has shown, strip curtains ( plastic pvc curtains, thermal curtains) can significantly save on energy consumption.

PVC strip curtains can be selected based on the following rule - the higher the opening, the greater the overlap (overlapping of the strips) and the width of the strip.

The price of PVC curtains depends on their type and width. You can order and buy pvc curtains in our company.

Strip curtains are divided according to their type into smooth and corrugated, and according to their width: 200x2 (mm), 300x3 (mm) and 400x4 (mm).

Types of PVC curtains

By type and purpose, PVC tape curtains are

– smooth

- corrugated

- non-combustible

– with special impregnation repelling insects

- frost-resistant curtains for cold rooms

Smooth PVC strip curtains are used for cold rooms, doorways of shops and enterprises, separation of working areas in enterprises - a transparent "wall" of curtains successfully performs the tasks of eliminating drafts, maintains the necessary thermal conditions, sound insulation, protects against dust, leaves and insects lets in enough light. However, it does not interfere with the free passage of personnel.

Corrugated PVC curtains have special stiffening ribs, they are recommended to be installed in the gate openings of enterprises and warehouses with a large flow of loading equipment. Curtain ribs are designed to exclude the moment of "sticking" to the parts of loaders and equipment, which happens with conventional curtains. The sliding resistance of such curtains, due to the longitudinal "ribs", is minimal. Curtain ribs reduce the contact area, thereby significantly reducing friction. In addition, the ribs of the curtains take all the load, which allows the main part of the curtain to remain clean and without scratches for a long time. At the same time, such curtains quickly take their original vertical position, closing and closing the opening.

PVC curtains for refrigeration and freezers
Frost-resistant PVC strip curtains for refrigerating and freezing chambers with temperature differences from -40 C° to +25 C°: PVC curtain for the refrigerating chamber (Silicone curtain) is designed to protect refrigerating chambers from cold / heat loss. Frost-resistant PVC curtains for refrigerating chambers contain a high percentage of special plasticizers, so such curtains retain the elasticity of the material and do not break at low temperatures. You can buy frost-resistant PVC curtains for refrigerators in Moscow at prices from the manufacturer.

PVC strip curtains
Non-combustible PVC strip curtains (non-combustible) are used in places of increased fire risk - warehouses with combustible substances, paper, paint. In the event of a fire, PVC curtains prevent the spread of fire throughout the warehouse or enterprise. Such curtains can be used in welding areas - they prevent the scattering of sparks during welding or metal processing. Strip curtains for welding work are produced with a special coating that acts as a filter to protect personnel from blinding by the welding arc.

Curtains with special impregnation have chemical composition repelling flying and crawling insects - flies, wasps, mosquitoes, horseflies, cockroaches, ants. The use of such curtains in public catering enterprises has shown their high efficiency.

Installation of PVC curtains

The device of fastening combs allows you to fix PVC plastic curtains in any opening of doors or gates. The length of the comb must correspond to the width of the opening. Installation of strip curtains is simple, can be carried out in short terms independently, and in case of large volumes or complex configurations of openings, it is better to contact our specialists - installers. For self installation silicone curtain, you need to mark the bottom line of the comb installation with a marker. The comb must be installed strictly horizontally. The comb is installed on self-tapping screws, anchors, dowels, depending on the wall material and installation locations. Required amount fasteners depend on the strength and material of the wall. The length of the strip curtains should be such that 2-3 cm remain from the bottom to the floor.

We carry out the installation of PVC curtains in Moscow and the Moscow region.

Nice garage- heated garage Even the most economical motorists will not argue with this. It is impossible to keep the gates permanently closed, and opening them, cold air from the street rushes into the room. This problem is solved by thermal curtains, which separate the cold air outside from the stable, comfortable atmosphere inside with an air stream.

Curtains, like gates, are different and are installed not only in garages. This material is devoted to the calculation of the optimal thermal curtain for the gate.

To choose a reliable and durable gate to choose a curtain in the room, then the following parameters should be taken into account:

1. Curtain dimensions according to the width and height of the opening.
2. Curtain power (outlet air temperature).
3. Air flow rate (air capacity).

Also take into account the type of coolant of the thermal curtain, the installation scheme and the method of controlling the device. In general, if you want to save time, the calculation of a thermal curtain for a warehouse gate, industrial premises or car washes are best left to professionals. You will only need to fill out a questionnaire, on the basis of which the designers will calculate in detail the required power and size of the air curtain.

And if the gate is wide?

For the curtain to be effective, there is a simple rule: the width of the curtain (at horizontal installation) must be greater than the opening width. If necessary, several curtains are mounted side by side to completely cover the width of the opening. It is better to choose a curtain that is larger in size than a smaller one - it will not work to save on this parameter.

The installation height directly depends on the air flow rate. The stronger the flow rate, the higher the curtain can be hung. The flow rate is indicated in the apparatus passport, as well as the recommended mounting height. The flow rate always decreases towards the bottom of the opening, this must be taken into account.

In addition, when choosing a curtain for a gate, an adjustment is made for the strength of the wind outside, which blows off the air flow of the curtain, for the air temperature outside. Such conditions in Russia are almost a fantasy.

There are many programs for calculating the flow of an air curtain. The maximum effect is achieved when professionals take part in.

Calculation example

Here is an approximate calculation for installing a thermal air curtain for a gate 1 m wide, 2.5 m high. Required condition- the presence of a vestibule.

For the given parameters, a curtain with a capacity of 900-1000 m³/h is required. According to the equipment passport of most modern air curtains, the outlet flow velocity will be 8-10 m/s, and at opposite side opening (below - with horizontal installation, and sideways with vertical installation) will be 2.5-3 m / s. The width of the curtain is at least 1 m.

Note that the recommended installation height is always given in the equipment passport.

Curtain power at given parameters must be at least 3 kW. Power is calculated based on the required 0.1 kW per 1 m² of unheated space with minimal heat loss.
