Industrial curtains for gates. Thermal curtains for the gates to the workshop

Thermal curtains The 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.
• Aerial models for warehouse doors use electricity to operate.

Electric options are much easier and faster to install. The installation price is also much cheaper, because it is easier to supply electricity to the structure than water. However, electric models will be more expensive to operate.

In the online store you will find vertical and horizontal models. If necessary, you can order their installation; check installation prices with our managers. We deliver throughout Moscow on our own, orders to other regions are sent by TK.

A thermal curtain is a device that creates air barrier on the gate and protecting the microclimate of the room from unfavorable environment.

Despite the fact that the system requires constant energy supply, it prevents the rooms from getting cold, reducing the cost of heating the workshop.

Thermal curtains provide optimal climatic conditions in large premises (workshops, warehouses, workshops, factories, etc.). The main functions of such devices are

• energy saving,
• air conditioning,
• personnel safety.

The advantages of thermal systems include the following factors:

• maintaining a microclimate at any time of the year;
• heat retention even with the gate open;
• creating a barrier against dirt and insects;
• unpretentiousness in maintenance;
• increased safety.

Disadvantages of the system:

• burning oxygen;
• noise during operation.

Types and their features

Air thermal curtain is a device with powerful fans, used to prevent air or contaminants from passing from one open space to another. Often used in cases where the gate to the workshop remains open for a long time. They help prevent insects and debris from entering the shop floor, creating turbulence. Heated models are used to provide additional warmth.

In some cases, systems are equipped with driveways, cargo gates and window openings. Cooling units are sometimes used in combination with cold storage rooms.

Main technical characteristics of the thermal curtain

Dimensions vary depending on specific models and gate heights.

• Large versions for cargo and warehouse doors reach 2115 mm.
• While compact models have a size of no more than 1037 mm.
• The least used option is the middle one, measuring 1576 mm.
• Compact models weigh no more than 90 kg, devices for installation on high gates can reach 200 kg or more.

On average, thermal curtains consume 5 kW during the entire operating time.

Automatic adjustment, when properly configured, saves even more energy. At the same time, problems such as untimely switching on of the unit during periods of unfavorable conditions are practically reduced to a minimum, since the system automatically regulates the device’s power and temperature.

Calculation of design and thermal power

The thermal power of the device is determined by the following formula:

Q = k × A × ΔT,

Where:

k— heat transfer coefficient of the device;

A— surface area of ​​the device;

ΔT- temperature difference.

For example, for a room of 16 square meters you will need a device with a power of at least 1.6 kW. In this case, the equipment is located across the entire width of the gate. The permissible deviation should not exceed 50 mm.

Remember one more rule - for every 10 square meters (with a ceiling height of up to 3 meters) 1 kW is consumed.

In this case, it is necessary to take into account that the ceiling and walls in the room must have their own thermal insulation. If it is missing, it will not be possible to create a comfortable atmosphere, since heat will pass through the walls.

When installing vertical models powered by heating, you can avoid purchasing expensive models with a heating function. In addition to the fact that the temperature in the workshop will be maintained, this will allow you to save on the purchase and installation of equipment, since models with a heating function are much more expensive.

Installation and maintenance

If the air curtain is supplied together with a wall mounting plate, do not try to replace it with a homemade analogue. If additional electrical accessories are included, install them according to the included instructions.

Before installation, make sure that the power supply in the room is suitable for the use of the purchased device.

For further work you will need:

• hammer drill,
• level,
• staples,
• anchor screws,
• bolts,
• screwdriver.

How to properly secure the curtain

1. Determine the exact installation location.
2. Remove the shield by removing the screws from the top, bottom, and front of the case.
3. Most often, curtains are equipped with four holes intended for wall mounting. If there are no holes, drill them yourself.
4. When using anchors for mounting, make sure they can support the weight of the device.
5. Secure the device, being careful not to touch the fan.
6. Make sure the structure is securely fastened.
7. Install a protective screen.

Connection

To connect the device, you must have experience working with electricity. Otherwise, contact a qualified technician!

To connect your device, follow these steps:

1. Remove the cover of the compartment intended for connecting to electricity.
2. Connect the power source and connect all wires according to the supplied diagram (depending on the model).
3. If you are sure that everything is connected correctly, press the start button.

Before testing the device, do not put on a protective shield, as further reinstallation of the equipment or its reconnection may be required.

1. If the fans are working and the device makes a characteristic noise, it means that everything is connected correctly and the system is ready for continuous operation.
2. If you encounter problems such as the fan not working or no electricity being supplied to the device, contact a specialist as it is not recommended to perform renovation work without having any specific qualifications.

Service

Air curtains require minimal maintenance as most models are fully automated. The only intervention is regular cleaning.

Remember - the dirtier and dustier the room, the more often and thoroughly it needs to be cleaned.

Cleaning

1. Turn off the power and lock the service panel to prevent the power from being turned on accidentally.
2. Remove the air intake grille to access the blower housing and motor.
3. Remove the bottom panel to access the fan housings.
4. Remove dirt, dust and debris.
5. Return all components to their original condition.

The following video clearly shows how to use a thermal air curtain in an unheated room:

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.

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: air flow under high pressure 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 gates. 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.

Curtains with top air supply are ineffective when stopped in the opening Vehicle. 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 air supply device ventilation or additional heating equipment.

Installation nuances

When calculating the curtain that will be installed in a warehouse or industrial premises, should be considered:

• the number of openings and the intensity of their operation (open periodically or constantly);
• whether vehicles will stop in the openings;
• 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 the 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 an optimal temperature at the bottom of the opening.

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 air flow taking into account changes in temperature outside and 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.
