Working principle of Holtop rotary heat exchanger
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%.
Product details
Wheel materials
The sensible heat recovery wheel is made by aluminum foils of 0.05mm thickness. And the enthalpy recovery wheel is made by aluminum foils coated with 3A molecular sieve of 0.04mm.
Casing construction
Wheel Construction
The wheel of the rotary heat exchanger is made of alternating layers of flat and corrugated aluminum foil to form the alveolate
shape. Various height of corrugation is available. Flat surface ensures minimum leakage. Interior spokes are used to mechanically bond the rotor’s laminations. These are threaded at the hub and welded at the periphery.
Bearing and drive system
The hub of the wheel is equipped with life-time- lubricated ball bearing or roller bearing, and with covers at both sides. No maintenance is required under normal usage.
- V-belt with big interface. Long service life.
- Spring shock absorber insures steady operation.
- Integrated motor and speed reducer free from maintenance.
Double sealing and purge sector system
Unique double-sealing system is installed around the rotor periphery and along the central beam. The sealing materials are soft and dense of small friction and longer service life.
Installation types and motor position
The motor is installed at the corner of the rotary heat exchanger, the position of the corner is marked from no. 1 to 4, and the motor position is optional.
Holtop is one of the best manufacturer in ERV/HRV, heat exchanger and AHU area in China, founded in 2002, areas covered more than 30,000 square meters, turnover of 2012 is 42 million dollars, we have enthalpy testing lab. for products test.
