Cooling capacities given by Bock at −10 °C evaporating and +40 °C condensing temperature, 20 °C suction gas, 50 Hz (EN 12900 standard). For another refrigerant (R448A, R449A, R407F, R513A…) or other temperatures, see the Bock catalogue (Documentation tab) or ask us to size it for you.
Each size comes in a standard version and an S version: the same compressor with a more powerful motor, intended for high evaporating temperatures, for example in air conditioning. Its cooling capacity is the same as the standard model. Horsepower (CV, metric horsepower) is calculated from the maximum electrical power input given by Bock (1 CV = 0.736 kW). The HGX12P/60-4 only comes as an S version.
The HG12P series
The HG12P is the smallest compressor in the Bock HG range: two cylinders, from 5.4 to 9.4 m³/h. Compact, it is used in small cold rooms, refrigerated display cabinets and low-capacity condensing units. It has everything Bock is known for: a motor that can be replaced on site, oil pump lubrication that works in either direction of rotation and INT69 G electronic motor protection.
