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