Working Principle

Rotary heat exchanger is composed of alveolate
heat wheel, case, drive system and sealing parts.
The exhaust and outdoor air pass through half of the
wheel separately, when the wheel rotates, the heat
and moisture are exchanged between the exhaust and
outdoor air. The energy recovery efficiency is up to
70% to 90%

The total heat wheel is made by aluminum foils coated with
3A molecular sieve of 0.04mm thickness. rotary heat exchanger2
Applications
Rotary heat exchanger can built in air handling unit (AHU) as a main part of the heat recovery section. Usually side
panel of the exchanger casing is unnecessary, except that bypass has been set in AHU.
 rotary heat exchanger application
It can also be installed in the ducts of ventilation system as a main part of the heat recovery section, connected by
flange. In this case, side panel of the exchanger is necessary to prevent leakage.  rotary heat exchanger application 2
Note: casing type and segment quantity should depend on the application spaces as well as transportation capability
and conditions at installation. Over segmentation will increase the assembly work, and overlarge size will cause
diffculties in transportation.
Application conditions
- Ambient temperature: -40-70°C
- Max face velocity: 5.5m/s
- Max pressure on casing: 2000Pa
