1.Heat from industrial waste gas with exhaust air temperature below 200°C can be recovered to heat fresh air

          2. The structure of heat recycle box can be designed according to the site situation.

          3. There is no feeding or exhaust fan in this structure.

          4. The heat recovery efficiency in this table is equal to the air supply and exhaust volume. You can consult our company for heat recovery efficiency with different air supply and exhaust volume.

          5. The heat recovery box can be made into floor type, ceiling type and other structural types (general air volume 100000m%/h to scare).
