Less than half a century, as the demand for heat exchange equipment in the form of an improved heat curtain in 1904, was widely spread in Europe. Today, you can feel the warm breath of the thermal curtains by entering the opening doors of large airports, train stations and offices.

To be frank, skepticism towards innovative technologies generates mistrust. So far, not many people decide to purchase and install such heat exchangers. We will help to discover the heat curtain.
To the barrier!
Modern heat exchanging equipment reliably settled in flats and houses. A variety of purpose-built units of supply ventilation systems supply cold and heated air to the premises. A thermal curtain, creating a temperature barrier from heated air streams flowing from one room to another, is considered a promising and highly efficient unit.
Explaining the meaning of the heat curtain, what it is, we will show that its principle of operation is based on overlapping the section of the passage or the room opening with a powerful heat flow. According to experts, the expediency of installing a jet curtain is preferable for constantly opening doors with a large flow of passage.
Intending to buy a heat curtain, it does not hurt to know the design and operation capabilities of the units, as well as the requirements for the organization of thermal protection.
Heat curtain отзывы
Alexander Lvovich, businessman
Our office is located near the metro station. We always have a lot of people - suppliers, managers and staff. Doors do not close, so it's cold in the office in winter. Install additional heating equipment is not rational. We conferred and bought a thermal veil of Teplomash. Simplicity of installation and connection captivates. Two specialists in almost an hour all done. Naturally, taking into account the requirements for creating thermal barriers.
Requirements for the organization of protective thermal barriers
The thermal curtain is referred to thermal engineering and climatological equipment, the organization of which is regulated by:
- SNiP 41-01-2003 "Heating, ventilation and air-conditioning", section 7.7.
- SNiP 23-01-99 * "Construction climatology".
For the organization of jet protection of the thermal curtain to the entrance door and the choice of power parameters, air flow and installation angle, it is recommended to take into account:
- height and width of the opening
- design temperature of the air inside and outside the room
- location of existing windows, supply ventilation, aeration lanterns
- degree of balance of the air mixture.
In addition, the choice of the unit is affected by the power of the thermal curtain, which determines the level of heat transfer capacity.
Helpful Tips
The purchase of expensive heat exchange equipment should be justified. Criteria for justification are: the purpose of the veil, the productivity and self-sufficiency of the acquisition. A hint is the classification and characteristics of the units: air curtains with a capacity of distillation of 300 m3 / h will provide the thermal barrier of the window, units with a capacity of up to 1000 m3 / h - door opening.
High performance in thermal curtains of electric, operating from 380 V. Weight of industrial curtains in steel bent body is more impressive in comparison with household models of units.
Construction of curtains equipment
The thermal curtain is structurally composed of the elements participating in the heat exchange process:
- steel ergonomic body with polymer coating
- electric heater under heat source
- high-performance fan heater
- air filter
- air duct with uniform heat distribution by the outlet nozzle.
The types of thermal curtains manufactured by the industry are structurally designed for various spatial installations and installation of industrial and household units.
types, classification and characteristics
There are curtains on the heating element (water and electric), performance and installation method.
The functions of heating mixing-type air curtains (household) and sliding type (industrial) are performed by:
- electric aggregates - heater and spiral
- water - hot water.
For the convenience of reading the parameters and characteristics of the curtain units, the standard marking for the series 100-600 is used, where the blocking effect of the unit corresponds to the power of the air curtain.
For example, the thermal curtain of the tropic is represented by the markings of a compact series T, K, A, M for installation in doorways up to 3 m with maximum capacity and capacity.
Helpful Tips
The water curtain can be used all year round. However, installing a water curtain will require a mixing unit that provides pressure and water temperature, as well as a pipeline to the CO system. Judging by the reviews, the thermal curtain of water, distinguished by a high cost, is difficult for self-installation. By the way, you should not choose a veil for heating, it has completely different functions.
How to choose the unit, shown in the video.
Ways to install thermal curtains
Depending on the product range, installation methods of the units assume a horizontal and vertical installation scheme.
The horizontal method of installation is most in demand. The curtain is installed above the doorway, taking into account the width of the working area of the unit, which exceeds the width of the door.
It is advisable to use a vertical air thermal curtain for narrow openings with a height of more than 3 m, the installation is carried out on one or two sides of the opening, taking into account the minimum distance from the wall of 200-300 mm.
Installation of the unit is carried out in the vicinity of the opening from the inside of the room. The layout of the curtains of garage or hangar doors is made depending on the overall dimensions of the opening.
We install the electric heat curtain with our own hands
The installation of a thermal electric curtain consists of the steps: mounting the unit in situ to brackets or frame structures (hangers and strips) and connections according to the attached scheme.
Any unit of industrial production is equipped on the rear panel of the housing with landing holes in the form of a lock well for fastening.
mounting technology
On the work surface we transfer the marking of the location of the grooves of the rear panel, we plan and drill the places under the fasteners taking into account the interaxial distance.
In the drilled holes we install mounting brackets, brackets, brackets or combs with installation steps of up to 0.5 m.
We fix the mounting element using anchors or bolts.
To prevent the self-loosening of fasteners, it is recommended to use washers with teeth made of spring steel with electro-zinc and engravers.
Prepared heat exchanger unit is hung or installed on the fastening element.
We make tightening fasteners.
Fixing screws tighten using torque wrenches.
Helpful Tips
The units of veils have a solid weight. If you add that in their work there is a vibration, then a simple standard fastening is indispensable.
Possible mounting options are:
- standard M10 bolts (main holes)
- safety clamps for horizontal installation
- threaded rods and suspension brackets for ceiling mounting
- connecting sets for connecting end joints
- damper gaskets for vibration damping.
unit connection
The condition for connecting the curtain assembly is a dedicated power line and a corresponding cable cross section.
For example, to connect to a three-phase network 380 V single-phase thermal curtain kev 4P121E to terminals A, B, C, N and ground use a five-core cable.
It does not hurt to remember that the unit is not recommended to be placed directly under or above the power outlet.
Any connection scheme ensures the safe operation of the equipment, so the necessary condition is the earthing of the housing and the power circuit components.
Useful information on the installation and connection of the curtain is shown here.
