The condensing unit is the outdoor half of a split system: compressor, air-cooled condenser and its fan, receiver, filter drier, sight glass, pressure switch and electrical panel are mounted on a single frame and arrive pressure-tested from the factory. On site, only the two pipes to the evaporator and the electrical supply are connected.

Open-type units are used under a roof or in a machine room; housed units sit outdoors inside a sheet-metal enclosure, run quietly and are protected from rain and sun. By compressor there are hermetic, scroll and semi-hermetic versions; by application temperature there are high (air conditioning, above +5 °C), medium (rooms around 0 °C) and low (−18 °C and below) temperature series.

In the catalog every unit’s capacity is tabulated by ambient temperature and evaporating temperature; a unit that gives 10 kW at 32 °C ambient and −10 °C evaporating gives a third of that at 40 °C and −30 °C. That is why the unit is selected for the room’s actual operating condition. Sonkar condensing units are manufactured at the factory in Konya; in our catalog condensing units can be searched by capacity, and the cooling load calculator leads directly to the suitable model.
