Heat Recovery Fresh Air Handling Unit Equipment Manufacturer
ISO-certified Heat Recovery Air Handling Unit manufacturer from China, featuring environmental friendliness and energy-saving design. An air handling unit (AHU) with heat recovery is a core HVAC (Heating, Ventilation, and Air Conditioning) device that integrates heat recovery functionality into a standard air handling unit.
Key Working Principles
A heat-recovery unit re-uses the air from the building to warm or cool new fresh air. A typical unit features two fans, one to reuse the building air (Return Fan), and the other to bring in fresh air (Supply Fan). What makes a heat recovery unit unique is the heat-exchange core. The core transfers heat from the outgoing stream to the incoming stream in the same way that the radiator in your car transfers heat from the engine's coolant to the outside air. It's composed of a series of narrow alternating passages through which incoming and outgoing air streams flow. As the streams of air move through, heat is transferred from the warm side of each passage to the cold, while the airstreams never mix. Westaire can implement different types of heat-exchangers which best accommodate your air temperature requirements.


JETEX Heat Recovery Air Handling Unit
Our company has developed an innovative heat recovery air handling unit that uses water as the thermal transfer medium. By employing specialized wet-film fillers, the unit facilitates cross-counterflow heat and moisture exchange between spray water and indoor exhaust air in an open-system total heat recovery process. During operation, the indoor exhaust air and outdoor fresh air remain entirely separated, completely eliminating air cross-contamination to ensure clean and healthy air quality. After open-system recovery, the air enters a sealed system, maintaining zero contact between exhaust and fresh air—100% cross-contamination prevention for guaranteed air purity.
Key features
- High Efficiency & Energy Savings
- Easy installation , can chose a multi-functional packed unit with exhaust air ,heat recovery ,fresh air functions or a single-function machine, to meet the usage needs of different environments such as new construction projects and renovation projects.
- Enhanced Heat Exchange Performance
By reducing airflow duration and volume through the heat exchanger, dust accumulation on its surface is minimized, indirectly improving thermal exchange efficiency.
