Small 2-cylinder semi-hermetic reciprocating compressors for medium/low temperature refrigeration and transport applications. These compressors are designed on the principle of standard reed valve type technology and feature an internal oil pump that guarantees optimum reliability in all operating conditions. The K-series ranges from 0.5 to 2 hp and the L-series from 2 to 5 hp with a displacement of 4 to 22.5 m3/h.

The 4S, 6S & 8S compressors have an internal capacity control, they work on the principle of blocking the suction
gas passage to two or more cylinders. They require the use of a special cylinder head and a control valve with
solenoid coil. These items may be ordered installed at the factory or in a kit form for later installation.
The suction port of the valve plate will be closed by a control piston (blocked suction). To prevent transport damage
the solenoid valve is supplied loose and the cylinder head is fitted with a shipping plate, therefore the shipping plate
with gasket must be removed and the solenoid valve with new gasket mounted. Do not put the compressor into
operation with the shipping plate this could result in erratic operation of the control piston and inadequate cooling
capacity.
