BOCK - HGX24e CO2 LT Subcritical 4-Cylinder Compressor

HGX24e CO₂ LT Subcritical 4-Cylinder Compressor

The BOCK CO_₂ subcritical 4-cylinder specialist compressor for low temperature applications with extraordinary requirements: HGX24e CO₂ LT.

When it comes to rare or challenging specifications the BOCK HGX24 CO₂ LT compressor is your reliable partner for low temperature applications with high LP standstill pressures up to 100 bar. HGX24e CO₂ LT is designed for evaporating temperatures from -50°C to 0°C, condensing temperatures up to 25 °C for example or for wide frequency bands, as well as wide operating limits.

The latest BOCK LT subcritical compressor combines 6 capacity stages in only one model and reaches stages from 4.6 to 12.7 m³ / h (50 Hz). The HGX24e CO₂ LT is available in motor versions ML and S and provides a flexible use for cascade and booster CO₂applications in supermarkets, as well as for commercial and industrial cooling.

The new highlight of our CO₂ compressor range for low temperature (LT) with high standstill pressures!
