Holtop Factory
Holtop is the No. 1 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. We cooperate with world famous brands in heat recovery wheel including YORK, McQuay, Carrier, DB, TRANE and SINKO.
Holtop total heat type heat/energy recovery wheels(rotary heat exchangers) can be widely installed into the air handling units and ducts for heat/energy recovery and air ventilation.
Laminar Flow Channels
The wave type structure of the wheel forms narrow channels in the direction of air flow. The air flow forms a laminar flow inside the wheel when passing through it. When the wheel rotates, dust won’t accumulate on the channel since outdoor air and exhaust air respectively flow through the channels from two directions. This is called self-cleaning.
Double Sealing 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.
Purge Sector
Because of the structure of rotary heat exchanger, the outdoor air and exhaust air will mix. According to the air velocity, wheel rotating speed and direction, purge sector is installed to prevent the exhaust air from entering the outdoor air. The purge sector enables a small fraction of outdoor air to blow back the exhaust air in the alveolate holes to its side. A minimum pressure difference of 200Pa between the outdoor air side and the exhaust air side is required to ensure the cleaning effectiveness. With all conditions provided, the sector can ensure a leakage below 0.3% from exhaust air to outdoor air.
