Thermal curtains for gates. Air curtains for warehouse and workshop gates Air curtains for industrial doors

IN winter time Every year in industrial and warehouse premises there is a problem with the entry of damp and cold air masses. This is especially true for the area at the entrances and doorways. To protect working personnel and maintain normal temperature in industrial premises, industrial thermal curtains for gates are used. They maintain an optimal microclimate for people and products and do not allow excess moisture to pass through.

Operating principle of thermal curtains

In warehouses with large gates, raw materials or goods are often unloaded and loaded. This creates constant changes in temperature and humidity. Such processes have a negative impact on products and raw materials, and especially on the health of workers.

Another significant disadvantage of temperature changes is increased heating costs. And in case electric heating and air conditioning also mean huge electricity bills.

An air thermal curtain is hung in the area where goods are loaded and unloaded and protects the room from cold flows. The device operates on the principle of a heat gun: a high-pressure air flow is supplied to the gate opening area. On some devices, air is supplied from the street, on others it is heated. The angle at which the air is supplied varies in the range of about 35-40 degrees. The convenience of the device is that it does not interfere with the passage of forklifts or the movement of personnel.

There are the following types of curtains:

• Shutterable - such curtains are equipped with a heater, which heats the air masses supplied to them to a certain temperature. They are often used where it is necessary to create a certain microclimate.
• Mixing devices - such devices take air from the street. Such devices are used for technical rooms.

Depending on the type of room, attention is drawn to one of these types of curtains.

Types of industrial curtains

Each thermal curtain has its own design features. Such devices are divided into several types:

• according to operating mode;
• by type of air mass intake;
• by location.

The operating mode of different air curtains for industrial doors also differs. For example, warehouse curtains can operate only during certain periods of time or continuously. In the first case, the device starts working only at the moment when the doors open. This solution is quite economical. However, for stable operation of periodic thermal curtains, it is necessary to establish their operation.

At the same time, devices that are constantly on can serve as an effective heating device. Often the devices are used for exhaust hood.

Industrial curtains differ in air direction:

• The flow spreads from bottom to top. In this case, there is a gap in the opening below.
• The air comes from above - the gap is placed above the opening.
• Horizontal flow - the slot is located on the side. Often such devices are used for large openings.

Each type of curtain has certain advantages that should be taken into account when choosing a device. For example, to select suitable type curtains for wide but low openings, it is worth paying attention to devices with bottom air supply. They allow you to effectively cope with the spread of cold air masses across the floor. However, such structures also have a significant disadvantage - they require frequent maintenance, because they are easy to clog.

Air curtains with top air supply are ineffective when vehicles are stopped in the opening. They are not able to hold back the flow of cold air passing under the car. For these reasons, side-mounted curtains are often installed at industrial facilities.

Devices located above the opening have another significant disadvantage - they are ineffective when the opening is high. If we classify air curtains according to the location of air intake, it is worth dividing them into the following types:

• with internal fence and heating- such devices take air directly from the room, which is protected from the cold;
• without heating;
• outdoor heated- air masses are taken from the street;
• the fence is carried out from outside, but the air is not heated.

Some curtains can be used as a supply ventilation device or additional heating equipment.

Installation nuances

When calculating the curtain to be installed in a warehouse or industrial premises, it is necessary to take into account:

• the number of openings and the intensity of their operation (open periodically or constantly);
• will they stop in the openings? vehicles;
• whether an air conditioning system is installed at the openings.

Depending on these indicators, certain standards for heating the air in the opening area and temperature indicators of the curtain are established.

Subtleties of calculation

Before buying a specific model of a thermal curtain, it is worth calculating the optimal performance of the system. They are built on the basis of initial data. This approach will improve energy efficiency.

The main parameters when carrying out calculations are:

• overall system performance depends on many factors;
• the speed at which air masses are blown out by a fan;
• air flow angle;
• opening size;
• heater power;
• coolant power.

Special methods are used for calculations. Each of them guarantees a certain accuracy of the result. Even a small inaccuracy in calculations can lead to significant loss of electricity.

Design features

A specific model is selected in accordance with the tasks being solved. For example, lower curtains are purchased for car gates. In this case, the device is installed at floor level. The direction in which the air will flow can be adjusted by installing special crevice nozzles.

If the gate will be located in a room where carriages often enter, it is worth taking a closer look at the vertical devices located on both sides of the opening. In this case, you can use both products with a fan for 2 racks at once, and independent devices. Air can be taken from different areas of the room.

A curtain located horizontally and mounted above the gate is used when the air flow does not exceed 38 thousand cubic meters. m per hour. If the curtain is installed on a high opening, it is better to use hot air (about 60 degrees). This will create at the bottom of the opening optimal temperature.

Often, in order to prevent the penetration of cold air masses into the room, a lower fence is used.

In addition, special attention is paid to the area of ​​the air duct through which the influx is carried out. fresh air. It should ensure uniform pressure of air masses.

Automation

To make it more convenient to control thermal curtains, special automation is mounted on them. Such equipment solves several problems:

• starting and stopping fans when opening and closing gates;
• constant change in temperature indicators of air flows taking into account changes temperature regime outdoors indoors;
• starting and stopping the air curtain when the outside temperature changes.

When installing automation on gates, the use of automatic control systems for thermal curtains helps to save on energy consumption and obtain a cost-effective engineering system.

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

You can order PVC curtains for gates right now from the World of MSK Curtains and find out the full cost using. But first, we suggest that you familiarize yourself with all the advantages of these products, which have proven themselves on the market as the most practical and inexpensive way solutions to many industrial and warehouse problems.

Advantages of PVC curtains for warehouses

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

The PVC curtain mounted on the gate can be reinforced using special installation. Silicone curtains with protective coating from insects, ultraviolet radiation, infrared lighting; to add wear resistance. However, we will consider the main advantages that distinguish PVC curtains installed on gates below:

• . Canopies effectively maintain temperature conditions and set level humidity, which allows you to conveniently store products of various types of consumption. Due to their high density, PVC curtains on gates effectively resist any drafts.
• Noise insulation. Mounted curtain for warehouse gates correct installation muffles noise well.
• Durability. Canopies have a long service life. In case of wear, the strips can be swapped or replaced with new ones individually.
• Versatility. PVC curtains for warehouses are suitable for covering openings of absolutely any width and height.
• Ease of use. Curtains do not obstruct the movement of vehicles. Natural light penetrates intensely through the thermal curtains. The curtains are easy to install and dismantle; if you wish, you can remove or replace the strips yourself.
• Easy to maintain. Simply wipe the curtains with a damp cloth to make them clean. No need to open and close manually.
• Safety of use. The use of canopies meets the technical standards, labor protection and safety rules established for workshops and warehouses. The plastic used is non-toxic and absolutely harmless to environment and human health.

Industrial curtains and drapes are economical!

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

Nice garage warm garage. Even the most economical car enthusiasts will not argue with this. It is impossible to keep the gates closed all the time, and when you open 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, come in different types and are installed not only in garages. This material is devoted to calculating the optimal thermal curtain for gates.

To choose a reliable and durable gate, to select a curtain for the room, you should consider the following parameters:

1. The dimensions of the curtain are in accordance with the width and height of the opening.
2. Curtain power (temperature of blown air).
3. Air flow speed (air capacity).

They also take into account the type of coolant of the thermal curtain, installation diagram and method of controlling the device. In general, if you want to save time, it is better to entrust the calculation of a thermal curtain for gates to warehouses, industrial premises or car washes to professionals. You will only need to fill out a questionnaire, based on which the designers will calculate in detail the required power and size of the air curtain.

What if the gate is wide?

For a curtain to be effective, there is a simple rule: the width of the curtain (at horizontal installation) must be greater than the width of the opening. If necessary, install several curtains side by side to completely cover the width of the opening. It is better to choose a larger curtain than a smaller one - you won’t be able to save on this parameter.

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

In addition, when choosing a curtain for a gate, allowances are made for the strength of the wind outside, which blows away the air flow of the curtain, and for the air temperature outside. Such conditions in Russia are almost fantastic.

There are many programs for calculating air curtain flow. Maximum effect is achieved when professionals take part.

Calculation example

Let us give an approximate calculation for installing a thermal air curtain for a gate 1 m wide and 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 data sheet of most modern air curtains, the flow velocity at the outlet will be 8-10 m/s, and on the opposite side of the opening (at the bottom when installed horizontally, and on the side when installed vertical installation) will be 2.5-3 m/s. The width of the curtain is at least 1 m.

Please note that the equipment passport always contains the recommended installation height.

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

Industrial thermal curtain: electric and water

Enterprises and industrial buildings, as well as residential buildings, need protection from cold air coming from outside. This problem becomes especially relevant in winter period time, when through constantly opening doors it passes a large number of heat. To provide 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 thermal curtain

Principle of operation

In various industrial premises with large gates, raw materials or other goods are often unloaded. In this regard, one has to deal with constant changes in temperature conditions, which negatively affects products and raw materials, as well as the condition of people working in a given place.

Besides. Due to temperature fluctuations, you have to overpay for heating. And if we're talking about about electrical system heating, then in in this case You will also need to pay large electricity bills.

The thermal air curtain is installed in the area where goods are loaded and unloaded and does not allow cold air flows enter 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 the air is directed to the gate opening area.

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

There are two types of curtains:

1. Shibatable.
2. The kit of such a device includes a heater, which is responsible for heating the air that enters the curtain.

Mixing.

Such devices take air from the street. They are mainly installed in technical rooms.

Types of industrial curtains

• Thermal curtains differ from each other in their design features. Depending on a number of criteria, several types of industrial thermal curtains are distinguished.
• Parameters on the basis of which curtains are classified:
• operating mode;

type of air mass intake; location. Industrial thermal curtains for gates differ in their operating mode. For example, curtains installed in warehouses. can function either continuously or for a certain period of time. For uninterrupted stable operation of the curtains, regular

Maintenance

. If we are talking about temporarily used curtains, then such a device begins to work only at the moment the gate opens. Considering these features, the device will be quite economical.

Automatic thermal curtain

• But, on the other hand, industrial air curtains, which are constantly turned on, will act as a fairly efficient heating device. Very often they are used as a hood.
• Another difference between industrial thermal curtains is the air direction:
• the flow can spread from bottom to top - this is ensured by a gap located at the bottom;

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

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

Electric thermal curtain

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

Based on the location of air intake, thermal curtains are divided into:

• devices with internal intake and heating, such structures take air from a room that is insulated 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 curtains can be used as air supply device ventilation or as auxiliary heating equipment.

Installation of an industrial curtain for gates

Electric industrial heat curtains can be installed in 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 their location, curtains can be vertical or horizontal. If you decide to install the structure horizontal type, then it is necessary to 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 observing all these installation requirements, you will protect the room as much as possible from cold air currents.

Calculation

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

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

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

High-pressure thermal curtain

Before purchasing a specific thermal model industrial curtain, it is necessary to carry out an accurate calculation of system indicators. They are identified based on the initial data. This way you can increase your energy efficiency.

Main parameters that should be taken into account when making calculations:

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

In order to make the calculation, there are several special techniques. Using any of them, you will get accurate results. It is necessary to carry out a 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 thermal curtain based on size range models.

Design Features

Each individual industrial curtain model is selected depending on its main purpose. For example, a bottom curtain is well suited for installation on garage doors. The direction of incoming air can be adjusted using special crevice nozzles that are mounted on the device.

If the gate is located in a room where carriages often enter, then pay attention to vertical models that are placed 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 is no more than 38,000 m³/hour. In the case when the curtain is mounted on a high opening, it is optimal to use hot air, approximately 60 °C. This way you will ensure the most optimal temperature in the lower part of the opening.

In addition, special attention should be paid to the area of ​​the air duct, which is responsible for the flow of fresh air. It is important to ensure uniform pressure of air masses.

Automation

For more convenient control of industrial heat 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 pauses 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 the temperature conditions change outside and in the building.
3. Starts and stops the air curtain if the outside temperature changes.

By installing automatic gates, you can save a significant amount of money due to the fact that reasonable consumption of electrical energy will be ensured.

Choosing a thermal curtain for a garage

Car enthusiasts often spend a lot of time in the garage. To ensure the most comfortable pastime without cold and dampness, install thermal curtain. Choosing this
equipment in the garage, it is worth considering a number of characteristics:

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

The most important parameter is the performance of the air curtain. The air supply speed and maximum height on which the device can be installed.

Also note the turbine, which acts as a fan.

Usually the turbine is located in the center of the curtain; it generates the required flow of warm air. On the market you can find models of air curtains with two turbines. The price of such units is lower, but they do not always meet user expectations. This is due to the fact that with curtains that have two fans located on the sides, the airflow of the heating elements may be uneven and there may be gaps in the center of the heated passage.

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

Eventually warm air will be directed straight down, forming thermal protection inside the garage.

Vertical structures are easy to operate 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 cold flow, even if the gate is open.

Thermal curtains for front door garage

The water thermal curtain is also popular. However, it is only suitable for those rooms where a central heating system is installed.

To summarize, it is worth noting that when choosing an industrial thermal curtain, you should pay attention to a number of factors: the intensity of the gate opening, the strength of the blowing wind on the street, design features the location in which the device is located, as well as the presence of ventilation in the room.

Thermal curtains for gates are designed to separate air flows and maintain indoor temperature. In enterprises, garages and warehouses, such systems are installed especially often.

The online store of the Moscow Engineering Center offers the purchase of models of various capacities with delivery throughout Moscow and other regions of Russia.

Varieties

• Thermal water curtains for gates use a water supply system for their operation.
