Industrial thermal curtain: electric and water

Businesses and buildings industrial type, just like 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

On various rooms production type with large gates very often unloads raw materials or any goods. 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 are talking about electrical system heating, then 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 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 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 both continuously and 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 curtains that are constantly turned on will serve as a fairly effective

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;

the air moves from above - in this case the gap is located above the opening;

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

Electric thermal curtain

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

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 a horizontal type structure, then you need 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 model of industrial thermal curtain, you need to accurately calculate the system performance. 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 the size range of models.

Design Features

Each separate model industrial curtain 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 zones premises.

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 best to use hot air, approximately 60 °C. This way you will ensure maximum optimal temperature at the bottom of the opening.

In addition, special attention should be paid to the area of ​​the air duct, which is responsible for the influx 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 it changes temperature regime on the street 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 a thermal curtain. Choosing this
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 door opening);
• power;
• type of heating elements;
• presence of control elements (remote control, 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 the 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.

The Termomir store offers customers a wide range of thermal air curtains. Heat curtains are sold wholesale and retail on the official website.

One of the most effective options protection from the penetration of cold air into the room is a thermal curtain. Wide by air flow The device separates the heated room from cold air from the street, protects against dust and insects, provides a comfortable microclimate in the entrance area, saves energy resources for heating, and in summer keeps air-conditioned rooms cool.
Air curtains are installed at the entrances of buildings with a large number of visitors: in shopping and entertainment centers, metro lobbies, cafes and restaurants, large offices, banks, clinics, etc.

Curtains come with heating - electric and water (on hot water), and also without heating - air.

Electric heat curtains operate from the mains, can be used for both domestic and industrial purposes, usually have several operating modes with power switching and can operate without heating ( summer mode). Air curtains with a power of up to 5 kW operate at a network voltage of 220 V, and from 5 and above - 380 V. Household air curtains are actively used for doors in country houses and dachas.

Water thermal curtains differ from electric ones in much greater power, therefore they are actively used for large objects - doorways and gates of large warehouses, shops, workshops, hangars, etc. Such curtains have a permanent installation, are connected to the main hot water and are characterized by high efficiency and air performance.

Air curtains without heating are used where it is necessary to separate the zone of heat and cold without additional heating. These devices are not equipped with heating elements, but work as large fans, allowing you to separate refrigeration chambers, zones or warehouses with chilled products from heated rooms, and prevent smoke and dust from entering other rooms, for example, in working shops and workshops, etc.

Thermal air curtains have the main specifications: power, air capacity and installation height. Based on these parameters, the calculation and selection of heat curtains is carried out. The dimensions, or rather the width of the curtain, are also important - it should be sufficient to cover the entire doorway, providing complete protection.
Thermal curtains are most often produced in horizontal version and are placed above the door or gate on the wall or ceiling. Vertical installation curtains are placed on the side of the doorway and have important characteristic no longer width, but height. Sometimes, with high doorways, several such curtains are used, installed one above the other. There are also universal installation models that are connected from the side or from above at the user’s request. Thermal curtains quite often come with a remote control remote control– keyboard, wired or wireless. This device greatly facilitates the use of the curtain and increases comfort. A large assortment of thermal curtains is presented below on the page and in the site menu. If you find it difficult to make a choice, contact our specialists for advice.

A thermal curtain is a device that creates an air barrier on the gate and protects 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 rooms (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

Sizes vary depending on certain 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. 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 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 heating-powered, you can refuse to purchase expensive models with 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 air curtain comes with wall mounting 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 protective screen by removing the screws from the top, bottom, and front of the case.

PVC strip curtains - effective method maintain the desired temperature (warm or cold) in the room: PVC curtains are what you need for your warehouse, workshop, store or production!

At many enterprises, the problem of energy saving arises due to constantly open doorways through which vehicles and personnel pass. Equipping openings with doors would be too inconvenient, 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 warehouse premises and stores.

With the constant opening of doors and gates for the passage of personnel or the passage of equipment, an exchange of air occurs between the room and the street. In winter, the room receives cold air and heating devices “warm the street”, and in the summer heat air conditioners cannot cope with their tasks.

PVC curtains for gates. Thermal curtains
PVC curtains for gates – perfect solution for entrance gates. PVC gate curtains are installed for workshop gates, warehouse gates and Garage Doors. Silicone curtains for gates are safe and resistant to loads during the passage of small to small vehicles. PVC curtains for gates open only part of the opening, according to the size of the passing person or the load being moved. PVC curtains for gates do not require the driver to exit: the equipment simply drives through the PVC curtains, and the curtains on the gates 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 next rule- the higher the opening, the greater the overlap (overlap of strips) and the width of the tape should be.

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

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

Types of PVC curtains

Depending on the type and purpose, PVC strip curtains are:

- smooth

- corrugated

- non-flammable

- with special impregnation that repels insects

— frost-resistant curtains for refrigeration chambers

Smooth strip PVC strip curtains are used for refrigeration chambers, doorways of shops and enterprises, separating work areas in enterprises - a transparent “wall” of curtains successfully performs the task of eliminating drafts, maintaining the necessary thermal conditions, sound insulation, and protects from dust, leaves and insects , transmits a sufficient amount of light. At the same time, 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. The ribs of the curtains are designed to eliminate the moment of “sticking” to the parts of forklifts and equipment, which happens with conventional curtains. The sliding resistance of such curtains, thanks to the longitudinal “ribs,” is minimal. The ribs of the curtains reduce the contact area, due to which friction is significantly reduced. In addition, the ribs of the curtains take the entire load, which allows the main part of the curtain to remain clean and scratch-free for a long time. At the same time, such curtains quickly return to their original vertical position, closing and closing the opening.

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

PVC strip curtains
Non-flammable PVC strip curtains (non-flammable) are used in places with increased fire hazard - warehouses with flammable 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 glare from the welding arc.

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

Installation of PVC curtains

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