Condensing Unit gas-cooled, 1-stage
SHG-L
The SHG condensers from Bock are a completely revised and optimized unit series with displacement volumes from 5 to 116.5 m³/h.
The newly developed and already tested compressors HG44e, HG56e, HG66e and the further developed types HG22e and HG34e were used here. In conjunction with our generously designed condensers, they are highly recommended for refrigeration applications with demanding ambient temperatures.

SHA-L COndensing units, 1-stage, Air-Cooled
Low-temperature cooling applications place higher demands on the compressor. The refrigerant mass flow is lower at low temperatures. Thus, the refrigerant is heated disproportionately by the drive motor.
Decreasing specific density and reduced efficiency are the consequences. The discharge gas and oil temperatures rise and the oil ages more quickly as a result. The lubricating properties deteriorate.
The BOCK SHA unit was specially developed for the low-temperature range.
The series is an efficient semi-hermetic solution for air-cooled compressors and works as follows:
- Compressor works direct-intake, motor is air-cooled
- Suction gas is not additionally heated but is drawn in directly from the compressor
- Motor is cooled via a ventilation unit
THE RESULT: INCREASED PERFORMANCE, EXTENDED APPLICATION LIMITS AND ADDITIONALLY AN OVERSIZED CONDENSER/FAN UNIT FOR SAFE COOLING!
Condensing unit air-cooled, 2-stage
SGHZ
SHGZ condensing units air-cooled 2-stage
The two-stage condensers of the BOCK SHGZ series are ideally equipped for extended use low temperature cooling and are fitted with BOCK HGZ7 compressors.
The two-stage compressors and the Bock "condenser-fan combination" provide sufficient power reserves. This condensing unit is ideal for demanding cooling applications such as shock freezing. The SHGZ series is already equipped with two-stage components as standard:
- Liquid subcooler
- post-injection valve
- Solenoid valve
- Sight glass
- Filter dryer
