The Louvered Recirculated Air Heating Unit by AirTS is an advanced heating solution designed specifically for high-ceiling spaces such as factories, logistics warehouses, aircraft hangars, and large workshops. With an optimized louvered air outlet and high static pressure fan design, this unit ensures rapid and even heat distribution from top to bottom, effectively solving the “warm top, cold bottom” problem common in tall buildings. Compatible with both hot water and steam heat sources, it provides a safe, efficient, and intelligent way to maintain a comfortable working environment while minimizing energy consumption.
Designed for spaces between 4 m and 30 m high, this unit delivers strong air throw up to 23 m, quickly distributing heat throughout working zones and preventing heat accumulation near the ceiling.
Compatible with 40–90 °C hot water or < 120 °C steam. Multiple control modes — including wireless operation, variable frequency control, and intelligent monitoring — ensure convenience and automation.
Equipped with a high static pressure axial fan and adjustable louvers, the High & Large Space AC directs warm air evenly across the workspace. No cold spots, no harsh drafts — just consistent comfort.
Integrated safety and control features include anti-fall alarms, data monitoring, VAV (variable air volume), wireless smart control, and self-cleaning air filters — ensuring reliability and low maintenance costs.
Compared to traditional ground-level heaters, this system pushes warm air downward, directly into occupied zones, reducing heat loss at the top. Smart frequency conversion further minimizes energy waste and operational costs.

Louvered Recirculated Air Heating Unit Working Principle
When hot water or steam passes the equipment, the efficient heat exchanger in the equipment is used to achieve rapid heating of the air.
The large wind pressure axial flow fan installed on the top is used to forcedly press the hot air down. Then the air is subject to pressure boost twice through the silencer sponge and the lower trapezoidal convergence, swirls out from the nozzle through the guide vane and is distributed throughout the space from top to down.

Technical Comparison
AirTS top heating unit
A high and large space air conditioner is lifted onto the roof
It achieves heating air from the air exchanger in the equipment
It distributes the hot air by means of efficient air distributor, which eliminate the undesirable indoor temp layers
Comfortable heating environment without wind feeling sense
Bottom heating unit
In high large space with great depth, using radiator can allow natural air convection as hot air rises
It can only radiate into small area with the range less than 5m. The heat rising to the roof will be dissipated and the temp cannot be achieved effectively in the middle area.
Radiator heating requires high requirements for supply water temp.
AirTS units temp field
Our heating units forcedly and quickly send the hot air down, make the temp in the working area rise rapidly.
Radiator heating temp field
It can be seen from the radiator heating temp field image that the heat is mainly gathered on the roof and the temp is low in the lower working area.

Frequently Asked Questions (FAQ)
A Louvered Recirculated Air Heating Unit is a high-performance heating device that circulates warm air from the top of a building down to the working area. It uses adjustable louvers and a powerful fan to distribute heat evenly, eliminating temperature differences between upper and lower spaces.
These louvered recirculated air heating units are ideal for large, high-ceiling environments such as:
● Industrial workshops and factories
● Logistics warehouses
● Aircraft hangars
● Printing and packaging plants
● Exhibition halls or gymnasiums
Any building with a height between 4 and 30 meters can benefit from this system.
The AirTS system supports multiple heat sources:
● Hot water: 40°C – 90°C
● Steam: Below 120°C
This flexibility allows integration with existing central heating systems, boilers, or renewable energy sources.
The system pushes heated air directly downward into the occupied zone, rather than allowing warm air to rise and accumulate near the ceiling. This reduces heat loss, lowers energy consumption, and shortens heating time — making it more efficient than traditional floor or wall-mounted heaters.
Yes. The louvered recirculated air heating unit supports intelligent control options such as:
● Wireless remote control
● Variable frequency drive (VFD) for fan speed adjustment
● Temperature sensors and automated operation modes
These features make the system energy-saving, easy to use, and highly adaptable to different environments.
Despite its strong airflow, the Louvered Recirculated Air Heating Unit operates quietly, thanks to precision-engineered fans and aerodynamic louvers. The noise level is well within industrial comfort standards, suitable for continuous operation during working hours.
Not at all. The louvered recirculated air heating unit is designed for low-maintenance operation with:
● Self-cleaning air filters
● Easy-access panels for inspection
● Durable corrosion-resistant construction
Routine cleaning and periodic checks are usually enough to maintain peak performance.
Yes. AirTS provides customized designs based on your workshop height, floor area, and available heat source. You can choose between different air outlet angles, fan types, and control modules to match your project requirements.
