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 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.


By adjusting wind speed and air outlet angle, it achieves comfortable heating environment

Supply air angle stepless regulation

Utilize axial fan to efficiently recover heat from the top, reducing heat loss from the roof, achieving energy-saving effects

High: continuously recover heat from the top space to send the heat to the working area at the bottom

Large: the devices in the space are arranged uniformly with even heat distribution

Space: decrease the temp of roof and surrounding walls, decrease the temp difference with the outside, and reduce heat loss

Long air supply distance, high hot air volume

Function: heating, fresh air supply

Bottom heating unit

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.
