Semi-hermetic HA compressors are primarily used 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.

| HA22P | 11.1 | 13.7 | 16.5 | |
| HA34P | 18.8 | 22.1 | 27.3 | 33.1 |
| HA4 | 40.5 | 48.2 | 56.6 | |
| HA5 | 62.9 | 72.2 | 82.2 | |
| HA6 | 93.7 | 107.6 | 122.4 |
