For industrial low temperature applications with high standstill pressures:

The 4-cylinder CO₂ compressor HGX24e CO₂ LT, which has been available since 17 May 2021, operates in six displacement stages and is available in the motor sizes ML and S. It thus offers a wide frequency range and greater operating limits, which increases operational flexibility. At the same time, risks, susceptibility to faults, operating and service costs are reduced. High efficiency, quality and reliability are also strengths of the new subcritical CO₂ compressor.

Climate-friendly and flexible in use:
For booster and cascade applications in commercial and industrial food refrigeration.

In CO₂ refrigeration systems, high pressures are not unusual and require a precise consideration of operating and standstill pressure to obtain the optimum design for the respective application.

The new Bock LT series can easily cope with higher standstill pressures that exceed the low-pressure range of 40 or 30 bar, because it is designed for pressures on the low-pressure side (LP) of up to 100 bar.

BOCK has addressed this issue with the LT compressor series for just such special specifications in low temperature applications: The subcritical HGX24e CO₂ LT operates highly efficiently at evaporating temperatures between -50 °C and 0 °C and condensing temperatures of up to 25 °C.

With a cooling capacity of 8 to 23 kW, the compressor offers performance in the small to medium capacity range with particularly high durability. The HGX24e CO₂ LT uses the natural refrigerant R744 and is climate-friendly and sustainable. The max. permissible pressures of the compressors are LP/HP 100/100 bar.
