The RefComp SRC-S and SRC-XS series screw compressors are helical twin screw oil-injected compressors(Picture 1-A shows an example with all the main parts and assemblies). The compressors feature a semi-hermetic construction, and are fitted with a three-phase asynchronous two-pole motor (2900 rpm at 50 Hz) directly coupled to the male rotor, which in turn drives the female rotor. These compressors are fitted out with a high-efficiency oil separator, whose position is different depending on the series (see chapter SA-02: “Lubrication”) and that allows the compressors to be installed in the refrigerant circuit without requiring any additional components. The motor is cooled by the intake gas that flows through special holes and grooves.

For the SRC-S series the capacity control is achieved by using a slide valve, which is moved by a hydraulic piston and which ensures part load operation by controlling the suction volume. For the SRC-XS series the capacity control is provided by a by-pass system, instead. In fact in these compressors part of the refrigerant mass flow is by-passed towards the suction side by suitable cylinders controlled by the refrigerant pressure.

The compressors of the SRC-XS and SRC-S series can operate with R22, R407C, R134a, R404A and R507 refrigerants.

The compactness, low noise, efficiency, completeness of the ranges and their simple installation make these series compressors ideal for the construction of a range of high-efficiency and modern water/water and air/water chillers and heat pumps. Moreover the SRC-XS series is specifically characterized by a high compactness because of the lateral oil separator, which in the SRC-S series is frontal, instead.
