Industrial Air Curtain
Preserves Indoor Air
While Your Doors Are Open
In industrial facilities, large doors are essential for production and logistics. But every time they open, indoor heat escapes while dust, humidity, and cold air find their way in. This leads to reduced efficiency and disrupted comfort.
EHP Industrial Air Curtains solve this problem with an invisible force. Installed above or beside doors, the system creates a powerful air barrier that covers the entire opening, blocking external factors. It maintains the interior climate, ensuring employee comfort and energy efficiency.
Why EHP?
🔹 100% energy-saving friendly
🔹 Advanced adaptive structure – seamlessly fits any environment
🔹 Blocks dust, humidity, and temperature imbalances
🔹 Silent, maintenance-free, and long-lasting performance
With EHP, energy stays in, and productivity stays high.

It is efficient and economical
Industrial air curtains provide savings of up to 80% in heat loss and leakage caused by doors. The annual energy losses in industrial doors in businesses where air curtains are not used are shown in the graph.
It is Comfortable and Healthy
It prevents possible discomfort in the conditioned environment by cutting off the air flow coming from the outside environment. It minimizes the effect of pollutants such as pollen, smoke, dust, etc. in the outside air on the indoor air quality.
Environmentally Friendly and Practical
Thanks to the energy savings it provides, it minimizes CO2 and Nox emissions, and provides the opportunity to reduce carbon footprint by being suitable for use with waste heat and renewable energy sources. It can be applied practically to all sizes of doors and environments.
Adaptive Blowing Technology
The control system and embedded software on the EHP with adaptive router can automatically change the angle of the air router by proportionally controlling the air drive motor according to the data it receives from the door switch. The air router of standard air curtains is fixed and does not have an adaptive operating system according to changing weather conditions.
As seen in Figure A, the air barriers formed by a standard air curtain with a fixed wing structure and an EHP adaptive air curtain are compared under variable conditions.
It can be observed that standard air curtains cannot adapt to variable conditions and cause energy loss, while the EHP adaptive air curtain perfectly adapts to changing conditions.
The relative energy costs of air curtains used on a door are shown in Graph A.
As can be observed from Graph B, an incorrectly designed or incorrectly selected air curtain application increases energy consumption instead of providing energy savings.
The EHP Adaptive Air Curtain is the most advantageous product in terms of energy efficiency.
Heating - Cooling (Apparatus) Mode
EHP Adaptive Air Curtains can also be used to support air conditioning systems when needed thanks to their ability to adjust the guiding angles.
EHP Air Curtains, which can switch to the apparatus mode by adjusting the guiding angles towards the interior when the doors are closed, contribute to keeping the comfort conditions stable by providing additional capacity to the air conditioning systems of the space. It can be adjusted 30º to both sides or oscillate 30º.
Water and gas battery models can support both heating and cooling systems; electric heater models can only support heating systems.
Homogeneous Speed Distribution and Low Noise Level
Layer Comfort System
It provides energy efficiency without compromising employee comfort on industrial doors.
The layer comfort system works on the principle of selecting the lower air curtain module as heated and the upper air curtain modules as ambient air in vertical installation. Thanks to this system, employees experience a sense of comfort with the blown warm air, while the upper modules that do not affect the employees create an air barrier using ambient air. This reduces both the initial investment costs and provides 50% energy savings in air curtain heating costs.
EC Engine Technology
EC Technology consists of a direct current (DC) motor that includes a converter, allowing it to be connected to an alternating current (AC) power source.
The stator (static part of the fan) contains an electronic control board that converts AC power to DC and also allows the fan speed to be proportionally regulated between 0 and 100%.
Unlike AC motors, EC motors have no slip losses, making them significantly more efficient.
Working Principle of an EC Motor
EC motors are brushless DC motors controlled by an electronic circuit board.
They feature permanent magnets and electronically determine rotation direction based on current flow.
They operate with alternating current power supplies, regardless of whether it’s 50 Hz or 60 Hz.
Advantages and Benefits
EC fan air curtains are highly efficient. By replacing AC fans with EC fans in air curtain systems, it is possible to reduce operating costs by up to 65%.
Energy Efficiency: Offers higher efficiency and lower energy consumption compared to air curtains with AC fans.
Long Service Life: Operates at a lower temperature than equivalent AC fan models, resulting in extended motor lifespan.
Control: Fan speed can be easily adjusted between 0–100% via 0–10V proportional control.
Simple and User-Friendly Operation: The electronic converter is integrated into the motor, making it compatible with both 50 Hz and 60 Hz power supplies.
EHP Air Curtain New Generation EC Blower Fan Technology
EHP’s new generation EC Blower Fans reach full power much faster than traditional EC fans, while also operating significantly quieter and with higher energy efficiency.
The graph shows the time required for standard EC fans and EHP’s new generation EC Blower fans to reach maximum speed.

What is an Air Curtain?
EHP
Industrial Air Curtain
WHAT IS AN INDUSTRIAL AIR CURTAIN?
Large doors are used in industrial buildings and when these doors are opened, indoor air conditions are disrupted.
Industrial Air Curtains are devices used in industrial areas such as factories and warehouses to protect the conditioned (heated or cooled) indoor air from cold-hot, humid, dusty and dirty air in the outside environment by creating an invisible air barrier, thus saving energy and protecting indoor air quality.
The devices are positioned on the doors or on the sides, providing an air flow that will cover the entire opening in the door section and creating an air barrier effect that will prevent air inlet and outlet.
Industrial Air Curtains: Preserve Comfort, Retain Energy
In industrial facilities, large doors frequently open and close, causing heated or cooled indoor air to escape rapidly. This results in significant energy loss and a decrease in indoor comfort levels. That’s exactly where Industrial Air Curtains come into play.
By generating a powerful and directional air stream across door openings, they block the entry of cold, hot, dusty, humid, or polluted air from outside. Acting like an invisible barrier, these systems protect the indoor environment from external factors while maximizing energy efficiency.
Advantages:
Reduces heat loss, enabling energy savings
Creates an invisible air wall at door openings
Requires minimal maintenance and ensures long service life
Offers adaptive control options for various operational needs
Maintains indoor air quality, promoting a healthier working environment
