Thermal curtains for electric gates. PVC strip curtains: strip curtains. Types of industrial curtains

AT 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 are used industrial thermal curtains for the gate. 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

Warehouses with large gates often carry out unloading - loading raw materials or goods. 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 the case of electric heating and air conditioning, there 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: a high-pressure air stream is supplied to the gate opening area. On some devices, the air is supplied from the street, on others it is heated. The angle at which air is supplied fluctuates 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 effective heater. 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.

Curtains with top air supply turn out to be ineffective when stopped in the opening of vehicles. They are not able to detain currents of cold air passing under the machine. For these reasons, side curtains are often installed at industrial facilities.

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);
will they stop in the openings vehicles;
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 specific model thermal curtain, it is worth calculating the optimal performance of the system. 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 with 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 an opening at the bottom optimal temperature.

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

Besides, Special attention refers to the area of the duct, through which the inflow is carried out fresh air. 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.

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 provide comfortable temperature and to 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 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 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:

Shibable. The set of such a device includes a heater responsible for heating the air that enters the curtain.
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 vehicles stop in the opening. 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 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:

The number of openings and the intensity of their operation (meaning how often they open).
Specify whether cars will stop in the openings.
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 receive 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 size range models.

Design features

Each individual model of industrial air curtain is selected depending on its main purpose. For example, for installation on garage car gate the bottom curtain works well. 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. Thus, you will ensure the most optimal temperature at the bottom of the opening.

In addition, special attention should be paid to 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:

First of all, the automation starts and stops the operation of the fans during the opening and closing of the gate.
Responsible for changing the temperature of the air flow, taking into account how it changes temperature regime on the street and in the building.
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. 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 should be noted 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 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 bring electricity to the structure than water. However electrical 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.

Good garage - warm 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 from the outside from the stable air with an air jet. comfortable atmosphere inside.

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:

Curtain dimensions according to the width and height of the opening.
Curtain power (outlet air temperature).
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. All you have to do is 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 the gate, an adjustment is made for the strength of the wind outside, which blows 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. Maximum effect achieved when professionals are involved.

Calculation example

Other publications on the topic

Here is an approximate calculation for installing a thermal air curtain for a gate 1 m wide, 2.5 m high. A prerequisite is 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 curtains, the flow velocity at the outlet will be 8-10 m / s, and on the opposite side of the opening (below - with horizontal installation, and on the side 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.

The air curtain power with the 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.
