Cooling capacities given by Bock for each size, with R404A at −5 °C evaporating and +43 °C ambient temperature, 10 K superheat, 50 Hz (Bock condensing units brochure). Fans, receivers, connections, dimensions and weights: Danfoss Bock condensing units operating guide (2023). For another refrigerant (R448A, R449A, R134a, R513A…), another temperature or a 60 Hz version, ask us to size it for you.
Each size comes in an L version (standard motor) and an SL version (more powerful S motor, intended for high evaporating temperatures, for example in air conditioning). On several sizes the SL version also has a larger condenser: more fans or a bigger receiver (see the table). Horsepower (CV, metric horsepower) is that of the compressor, calculated from its maximum electrical power input given by Bock (1 CV = 0.736 kW).
The SHG44e series
The SHG44e unit combines on one base frame a Bock HG44e four-cylinder semi-hermetic compressor (see the Bock HG44e compressor), a generously sized fin-and-tube air-cooled condenser and a liquid receiver. Its high-efficiency AC fans (230 V single-phase) accept speed control to adjust the condensing pressure. Bock sizes this condenser for very hot regions: the capacities above are given at +43 °C ambient. Supplied with ester oil (SHGX version), it runs on common HFC and HFO refrigerants (R404A, R448A, R449A, R134a, R513A…). They suit large cold rooms, cold stores and cooling tunnels.
