They efficiently adjust heating and cooling capacity for diverse applications, ensuring reliability and durability.For specific low-temperature requirements with evaporating temperatures from -50°C to 0°C and condensing temperatures up to 25°C, we offer an efficient HG CO2 LT variant designed for subcritical CO2 systems with high standstill pressures (LP 100 bar), available in two motor versions (ML and S) to accommodate a wide frequency band and extended operating limits.

BOCK®'s CO2 semi-hermetic compressors offer versatile, cost-effective solutions with wide operating limits. They efficiently adjust heating and cooling capacity for diverse applications, ensuring reliability and durability.The HG CO2 T transcritical compressors are gas-cooled, semi-hermetic reciprocating compressors that are capable of operating at pressures up to 130 bar. They are specifically designed for transcritical CO2 systems, with standstill pressures of 100 bar on the low-pressure side and 150 bar on the high-pressure side. These compressors are known for their highest compressor and system efficiency, which is achieved through a design that is specifically tailored for CO2 applications.

BOCK®'s CO2 semi-hermetic compressors offer versatile, cost-effective solutions with wide operating limits. They efficiently adjust heating and cooling capacity for diverse applications, ensuring reliability and durability. Series with LSPM motor technology (LSPM=Line Start Permanent Magnet) with otherwise the same technical characteristics as the series with standard asynchronous motor. The higher efficiency of the LSPM motor technology results in increased efficiency and lower operating costs at the same time. Synchronous operation without slip and thus higher speed compared to standard asynchronous motors with the same robustness. Thus higher refrigerant mass flow with more cooling or heating capacity.No power losses in the rotor, resulting in higher motor and overall compressor efficiency (by an average of about 6 percent compared to a standard asynchronous motor). Operation can be flexible on the mains or via a frequency converter
