Compact screw compressors with integrated oil separator
KS is a complete range of compact screw compressors with displacements between 410 and 810 m3/h (50 Hz) for applications with HFO, HFC and natural refrigerants such as Propane and Isobutane. Step or stepless capacity control in the range 25 … 100%. Wide possibility of customization thanks to a wide choice of complementary accessories and a large variety of electric motors available.
Vertically removable and replaceable oil filter without the necessity of the crankcase’s emptying and vacuum operation.
Optimized ergonomics with most connections located on the same side: this makes the control and service operations easier.
Minimized oil expulsion thanks to the use of innovative and patented separation technology.
Intelligent oil interception system: it allows the application of external accessories such as oil flow switch or oil cooling heat exchanger without the necessity of previously evacuating the refrigerant.
Oversized bearings and rotor crankshaft: greater reliability and stability at high rotation frequencies over 50 Hz (application with inverter).
Standard compressor designed for the application of an external inverter.
Manually selectable Vi by the user at any time: 7 available steps in the range 2.2 … 4.4.
Variable Vi in steps with hydraulic control through solenoid valves.

The electrical data shown in the 2 tables are referred to KS compressors with standard motors, optimized for “low pressure” (e.g. R134a, motor size S) and “high pressure” (e.g. R407C, motor size F) refrigerant fluids respectively. Other motors are available for particular uses.
* Compressor equipped with motor size “S”, optimized for low pressure refrigerants (es. R134a, R513A, R1234ze). Power supply 400V/3/50Hz – 460V/3/60Hz
** Data refers to application with refrigerant R134a
* Compressor equipped with motor size “F”, optimized for high pressure refrigerants (es. R407C, R290). Power supply 400V/3/50Hz – 460V/3/60Hz
** Data refers to application with refrigerant R407C
