Heat Recovery

Lumber kilns typically use crossflow air-to-air heat exchangers with painted aluminium. Another variant uses stainless steel cooling coils to extract heat from exhaust air, which is then transferred via water pipes to a heating coil. We manufacture our own efficient crossflow air-to-air heat exchangers in stainless steel, as well as the water-based variant. For the water-based system in channel kilns, we offer stainless steel cooling coils with copper fins. The heat is then transferred via water to a heating coil made of stainless steel with aluminium fins.

For chamber kilns, coils with copper fins on both sides are required.
