1.1 General description
GR110 up to GR200 and GR110 W up to GR200 W are two-
stage, oil-injected screw compressors, driven by an electric
motor and enclosed in a sound-insulated bodywork.
GR110 up to GR200 are air-cooled, abbreviated as "GR".
GR110 W up to GR200 W are water-cooled, abbreviated as
"GR W".
GR Full-feature (FF) compressors are provided with an air
dryer integrated in the bodywork. The system includes dryer
by-pass valves.
1.1.1 Main options
Full-feature
A refrigerant dryer is fully integrated into the bodywork of the
compressor. This “all-in-one” feature reduces the required
space for installation and provides savings on piping installation
cost.
Integrated DD filter (only on GR (W) 13 bar/200 psi)
Full-feature compressors can be provided with an integrated
filter of the DD type to limit carry-over of solid particles and
oil. By integrating a DD filter, the GR Full-feature turns into a
fully integrated compressed air station delivering Quality Air
according to ISO 8573-1, Class 2.4.2.
