Leakage - VN System


Many designs of rotary heat exchanger are prone to leakage drift, where leakage increases significantly over a period of time. It may raise power consumption in the fan, increase velocities in the precipitators, reduce the flow of hot air to the mills, or shrink the draught fan margins.

By fitting our advanced Howden VN sealing system, these problems can be reduced or eliminated. The VN system uses fixed sector plates and double sealing and has proven its value in over 1000 installations worldwide.
