Page 12: General Description
HSS 3100 Series Operators Manual General Description The J & E Hall International HSS 3100 series of semi-hermetic integral compressors are the latest addition to the HallScrew family of oil injected, positive displacement, single screw compressors. Reflecting the very latest innovations in screw compressor technology, they are designed for incorporation into factory built DX chillers using R407c, R134a or R22, having independent refrigeration circuits for each compressor. - Page 13 HSS 3100 Series Operators Manual The compressor consists of two cast-iron castings which are bolted together. The first casting is divided into two parts: the main casing, encloses the motion work comprising the main rotor and star rotor, the motor housing encloses the 3 phase, 2 pole motor. Returning suction vapour flows around the stator/rotor unit, cooling the windings in the process, before entering the main rotor flutes.

Page 31: Integration Into The Refrigeration Circuit
HSS 3100 Series Operators Manual Integration into the Refrigeration Circuit The HSS 3100 compressor is an oil injected screw type. The integral oil separator is a cyclone type and works on a centrifuge principle. Oil separators are not 100 % efficient, so the system must be designed to return any oil carried over into the system from the separator, back to the compressor. -
