This air-to-air heat recovery unit is designed for integration into an exhaust air system with a high dirt load, e.g. dust, aerosols from industrial exhaust air after drying processes. To cool the process exhaust air, the cold fresh air is passed through segments in a counterflow process.

Function

- During operation, this segment design provides a large heat transfer surface for optimum utilisation for heat transfer from the hot extract air to the cold fresh air.
- Clean fresh air flows through the segments
- No radiation losses, as the heated fresh air is returned directly to the system with optimised heat transfer (segment design).

Use

- No change to the existing process lines
- Economical to use from 1300 m³/h upwards

Technology & material

- Stainless steel design
- Low pressure drop

Installation & maintenance

- Modular construction, fully assembled and ready for direct installation
- Low space requirement
- The unit is integrated into the existing exhaust air duct without changing the exhaust air duct.
- Minimal cleaning effort
