Compressor Features:

Package Features:

Proprietary line-generated rotor profile and
optimized rotor dimensions for improved
volumetric efficiency and lower power
consumption.

Multi-stage oil separator design guarantees low oil
loss.

5:6 male to female lobe ratio for improved
bearing load distribution, lower noise
generation, and better bhp/ton performance.

High performance, all steel, flexible disc coupling
with factory assembled center member for quick
installation and removal.

Patented flow-optimized suction inlet improves
volumetric efficiency and reduces noise.

Unique keyless frictional coupling hub on the
compressor end provides an easily adjustable and
releasable mechanical shrink fit. This feature
provides all the benefits of a shrink fit, but without
the problems.

High performance cylindrical axial roller
bearings and duplex angular contact ball
thrust bearings.
Double-acting hydraulic capacity control,
infinitely adjustable from 10% to 100%.
Unique Hermetic Differential Transformer
(HDT) transmits slide valve position without
wear or friction and requires no external seal.
Integrated suction strainer and suction check
valve.
Internal oil pump for capacity control on high
stage units.

Three-way thermostatic oil temperature control
valve standard with oil cooler options.

Shimless motor mounts provide fast, easy, and
accurate motor alignment checks.
Advanced GForceTM microprocessor control panel
is standard with options for refrigeration system
