5. Life-time-lubricated bearing requires no maintenance under normal usage.
6. Interior spokes are used to mechanically bond the rotor’s laminations to reinforce the wheel.
7. Completed range of rotor diameter from 500mm to 5000mm, rotor can be cut into 1pc to 24pcs for easy transportation,various types of housing construction is available as well.

8. Selection software for convenient selection.

Working Principle

Rotary heat exchangers 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%

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.

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.

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
