BITZER Compact Screws are of two-shaft rotary displacement design with newly developed profile
geometry. The main parts are male and female rotors, fitted into an enclosed housing precisely located at
both ends in roller contact bearings (radial and axial).
Owing to the specific design this type of compressor does not require any working valves. To protect
against reverse running when the compressor is switched off (expansion operation) a check valve is
incorporated in the discharge chamber.
An internal pressure relief valve is fitted providing over pressure protection.
The compressor is driven by a three-phase asynchronous motor which is built into the compressor
housing. The motor rotor is located directly on the shaft of the male screw rotor.
Motor cooling is achieved by the returning cold refrigerant vapour which mainly flows through the bores
in the motor rotor.

The ease and efficiency of liquid sub-cooling is one of the special features of the Bitzer CSH screw compressor
which confirms its superiority above similar semi-hermetic screw compressors in the market today.
A part of the refrigerant mass flow from the condenser enters the sub-cooler via an expansion device, and
evaporates upon absorbing heat from the counter flowing liquid refrigerant (sub- cooling).
The superheated vapour is taken in at the compressors ECO connection, mixed with the mass flow from the
evaporator and compressed to a high pressure.
The ECO connection enters the compression chamber through the loading slide valve. This allows the subcooling heat exchanger to operate on a consistent evaporation temperature ensuring minimal sub cooled liquid
temperature changes with-out the use of other evaporator control valves.
This design provides an overall balanced and stable system operation even during part load conditions.
