Wheel materials: the sensible heat wheel is made by aluminum foils of 0.05mm thickness. The total hygroscopic thermal wheel heat exchanger is made by aluminum foils coated with 3A molecular sieve of 0.04mm thickness. Molecuar sieve selectively

absorbs moisture and expels odor by molecular lattice.

Wheel construction: The mass of thermal wheel 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.

Laminar flow channels with self-cleaning, Double sealing sysem around rotor periphery and central beam.

Purge sector: ensures the cleaning effectiveness and ensures a leakage below 0.3% from exhaust air to outdoor air.

Bearing and lubrication: life-time lubricated ball bearing or roller bearing, and with covers at both sides. No maintenance needed under normal usage.

Driving system: The drive system is composed of motor, turbine-worm reducer, belt pulley and V belt. The motor is installed on the special bracket tensioning by the spring, it can ensure the gradually loose of V-belt in case of sudden stop.

Operation control: optional.

 Eurovent heat recovery wheel can be built in air handling unit(AHU) as a main part of heat recovery section. Usually side panel of the exchanger casing is unnecessary, except that bypass has been set in AHU.

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. As a leader in energy/heat recovery equipments, we cooperate with more than 30 famous companies who located in Europe, the Middle east, Korea, Southeast Asia, Taiwan, etc. supplied equipment to Beijing Olympic and Shanghai Expo 2010, works together with domestic and international brands like Midea, Haier, Hitachi, etc.
