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); the SHGX12P/60-4 only exists as SL. The condenser and receiver are the same in both versions. 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 SHG12P series
The SHG12P unit combines on one base frame a Bock HG12P two-cylinder semi-hermetic compressor (see the Bock HG12P 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…). These are the smallest Bock units: they suit small chilled and frozen cold rooms, display cases and refrigerated cabinets.
