HA single-stage compressors
The HA-system - the best solution for deep-freezing!

Special features:
- Direct intake with external ventilation
- Suction gas intake directly into the compressor
- Motor cooled by an integrated ventilation unit

This reduces the compressed gas temperature and thus expands the range of application while at the same time increasing capacity (deep-freeze, R22, R404A). At the same time, the compressor is physically separated from the compressor, with advantages particularly in the case of motor damage.
