HGZ two-stage compressors
Based on the
6-cylinder compressor HG7, a selection of two-stage variants are available for
extended use in intense cooling.
The selection of the liquid intercooler unit
is available for three different refrigerants: R404A (R507), R410A, R22.
Basically it concerns different expansion valve assemblies.
Therefore in the further descriptions only one option (e.g. HGZ7/2110-4 R22) is
The optional two-stage system is composed of:
- a liquid
- expansion valve
- solenoid valve
- sight glass
The two possible optional variants of the
Intermediate pressure line mounted and
Liquid supercooler, expansion valve, solenoid valve, two sight
glasses, filter dryer everything enclosed separately for individual,
Liquid supercooler, expansion
valve, solenoid valve, two sight glasses, filter dryer attached directly to
the compressor, lined and insulated.
- Six-cylinder construction
- Stages divided into
LP / HP at the ratio of 2 : 1
- Two-stage operation with liquid
- Expansion valve adjusted to refrigerant and application
Extremely economical and reliable concept
