How to choose a thermal curtain for the gate. Industrial thermal curtain: electric and water Thermal curtain for gates

IN Lately The use of thermal curtains has become very popular. Their main purpose is to prevent the mixing of air masses in different zones Oh. Simply put, there is a separation of air spaces: for example, when you need to separate the room and the street. The most popular model is . Therefore, the question of how to choose is very relevant.
Characteristics of thermal curtains
Characteristics by which they divide:
1) By dimensions. The main criterion here is the length. It should approximately equal the height or length of the opening (depending on the installation method).
2) Type of coolant. There are 3 main types: electric, water, gas. They possess various properties, so the choice is made based on the parameters of the order.
3) Orientation during installation. With this characteristic, you can choose how to install the equipment. There are 4 ways: vertically, horizontally, vertically - horizontally, ceiling.
4) Scope. The parameter describes the range of the air curtain. IN common cases enough range of the size of the opening plus a small margin.
If all this is summed up, then you can choose exactly the curtain that you need. For example, if you need to produce according to ready-made formulas, and choose the right one from the presented.

Which veil to choose?

On domestic market there are 2 worthy companies in which they can produce: Teplomash and Tropic. Each of them has several series, in which there are goods of different directions and configurations. The choice is offered:
1) Series X - cover openings up to 6 meters. There are vertical and horizontal installation.

4) Series M - used where a high air flow rate is required. Height up to 3 meters. Vertical installation.
5) ZTV series - Curtains using water as an energy source. They are installed in rooms with large openings, but insufficient electrical power. Height 3.5 - 4 meters.
Conclusion
It is very easy to choose this device. It is enough to know a few parameters and make simple calculations. If you cannot produce, then you can calculate the thermal curtain on the gate online on various resources. With the correct analysis of all parameters and taking into account all preferences, you can get a quality product that will delight you for many years with its work.

Industrial thermal curtain: electric and water

5 (100%) votes: 2

Businesses and industrial buildings, as well as residential buildings, need protection from cold air coming from outside. This problem becomes especially relevant in the winter, when through the constantly opening doors leaves a large number of heat. To provide comfortable temperature and prevention of 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 various production-type premises with large gates, unloading of raw materials or any goods is very often carried out. 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 in this case it will also be necessary to pay large bills for electricity.

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 of 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 similar devices installed in 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 vehicles stop in the opening. Such designs do not delay the flow of cold air masses that pass under the machine. Considering this fact, industrial and production facilities side curtains are usually installed.

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 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 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 a thermal industrial curtain, it is necessary to carry out an accurate calculation of the system indicators. 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 make a calculation, there are several special methods. 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.

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 where wagons often enter, then in this case, pay attention to the 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 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 optimum temperature at the bottom of the opening.

Besides, Special attention it is worth giving the area of ​​\u200b\u200bthe duct, which is responsible for the flow of 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 the temperature regime changes on the street and in the building.
  3. Starts and stops the air curtain in case of change temperature regime on the street.

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 (as in the case of industrial premises, it must exceed the width of the doorway);
  • 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. The air supply rate and the maximum height at which the device can be installed will depend on it.

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 of 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 airflow 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, the heating elements located inside the metal case will be located directly above the doorway or above the gate.

Eventually warm air will go 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 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 wind blowing outside, design features the place where the device is located, as well as the presence of ventilation in the room.

Thermal curtains on the gate are designed to separate air flows and maintain the temperature inside the room. At enterprises, in garages and warehouses, such systems are installed especially often.

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

Varieties

  • Thermal water curtains on the gate use a water supply system for their work.
  • Air models 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 bring 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 the prices for installation with our managers. We deliver in Moscow on their own, orders to other regions are sent by shopping mall.

IN winter time years in industrial and warehouse premises there is a problem of getting wet and cold air masses. This is especially true for the area at the entrances and doorways. To protect operating personnel and maintain normal temperature industrial premises use industrial thermal curtains for gates. They maintain an optimal microclimate for people and products and do not allow excess moisture to pass through.

The principle of operation of thermal curtains

In warehouses with large gates, unloading and loading of raw materials or goods is often performed. This creates constant fluctuations 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 fluctuations is the increased heating costs. And in case electric heating and air conditioning are also huge electricity bills.

An air thermal curtain is hung on the territory of loading and unloading of goods and protects the premises from cold streams. The device works on the principle of a heat gun: air flow under high pressure applied to the area of ​​the gate opening. On some devices, the air is supplied from the street, on others it is heated. The angle at which 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 and the movement of personnel.

There are such types of curtains:

  • Shibable - such curtains are equipped with a heater, which warms up the air masses supplied to them to a certain temperature. Often they are used where you need to create a certain microclimate.
  • Mixing - such devices take air from the street. Such devices are used for technical premises.

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 the mode of operation;
  • by type of air mass intake;
  • by location.

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

At the same time, devices that are in a constantly on state are able to play the role of an efficient heating device. Often devices are used for hoods.

Industrial air curtains differ in air direction:

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

Each type of air curtain has certain advantages that should be considered when choosing a device. For example, in order to choose the appropriate type of curtain for wide but low openings, you should pay attention to devices with a bottom air supply. They allow you to effectively cope with the spread of cold air masses on 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 stopped in the opening Vehicle. They are not able to detain currents of cold air passing under the machine. For these reasons, often industrial facilities install side curtains.

Devices located above the opening have another significant disadvantage - they are inefficient at high opening heights. If you classify curtains according to the place 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 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 a curtain that will 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);
  • whether vehicles will stop in the openings;
  • whether the air conditioning system is installed at the openings.

Depending on these indicators, certain norms for heating the air in the opening zone and temperature indicators of the curtain are set.

Subtleties of calculation

Before buying a specific model of a thermal curtain, it is worth calculating optimal performance systems. They are based on the original data. This approach will improve energy efficiency.

The main parameters in the calculations are:

  • overall system performance - depends on many factors;
  • the speed at which air masses are blown out by the fan;
  • angle of inclination of the air flow;
  • opening size;
  • heater power;
  • heat carrier power.

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

Design features

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

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

The 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 air curtain is installed on a high opening, it is better to use hot air (about 60 degrees). This will create the optimum 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 duct, through which fresh air is supplied. It should provide 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:

  • start and stop fans during opening and closing of the gate;
  • constant change in the temperature indicators of air flows, taking into account changes in the temperature regime on the street in the room;
  • start and stop 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 electricity consumption and obtain an economically beneficial engineering system.

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

Despite the fact that the system requires a constant supply of energy, it prevents the premises from cooling down, reducing the cost of heating the workshop.

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

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

The advantages of a thermal system include the following factors:

  • maintaining a microclimate at any time of the year;
  • keeping warm even when the gate is open;
  • creating a barrier against dirt and insects;
  • unpretentiousness in service;
  • security enhancement.

Cons of the system:

  • burning oxygen;
  • noise at work.

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, creating turbulence. Heated models are used to provide extra warmth.

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


Main technical characteristics of the thermal curtain

Dimensions vary depending on certain models and door 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 is the middle version with a size of 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 working time.

Automatic adjustment with the correct setting saves even more energy. At the same time, problems such as untimely switching on of the unit during unfavorable conditions are practically minimized, since the system automatically regulates the power of the device and the temperature.

Design and thermal power calculation

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

Q = k × A × ∆T,

Where:

k— heat transfer coefficient of the device;

A— surface area of ​​the device;

∆T- temperature difference.

For example, for a room with an area 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. Tolerance 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 must be taken into account that the ceiling and walls in the room must have their own thermal insulation. If it is absent, 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 refuse to buy expensive models with a heating function. In addition to the fact that the temperature in the workshop will be maintained, this will save on the purchase and installation of equipment, since models with a heating function are much more expensive.

Installation and maintenance

If air curtain supplied with wall mounting plate, do not try to replace it with a homemade counterpart. If the kit contains additional electrical accessories, install them in accordance with the attached instructions.

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

For further work you will need:

  • perforator,
