5. 3A molecular sieve coating for total heat type.

6. Both sensible and total type are available.

7.saving Installation space

Working principle of  Eurovent certified 3A molecular sieve ERV rotary  exchanger 

The aluminum covering 3A molecular sieve rotor diameter 500-5000mm hygroscopic heat wheel  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 to70% to 90%.

Professional Selection Program for rotary heat exchanger to mare sure accurate selecting.

We have developed a calculation program for simple selection of a rotary heat exchanger model. It can not only be used as a single design selection program, but can also be combined into your program by DLL. We can add it to your program upon your request, too.

Specifications and dimensions of rotary heat exchanger

Application of rotary heat exchanger

Rotary heat exchanger (wheel) is mainly used in building ventilation or in the air supply/discharge system of air conditioning equipment. The wheel transfers the energy (cold or heat) contained in exhaust air to the fresh air supplied to indoor. It’s one important equipment and key technology in the field of construction energy-saving.

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.
