Grasso's reciprocating compressor range includes 48 Grasso models of compressors subdivided into 6 series: Grasso 12E, Grasso 12, Grasso 10, Grasso 6 and Grasso 5HP as open type compressors and the Grasso 7S and Grasso 8S as semi-hermetic ammonia compressors.
The Grasso 12E, Grasso 12 and Grasso 10 series have an unique welded steel crankcase that ensures an extremely high heat dissipation, which allows operation without cylinder head cooling and oil cooling in most applications. Reciprocating compressors have the following features in common, and have been developed to meet the specific needs of respective appliances, thus being highly recognized by the customers throughout the world.

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, R410A, 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 two-stage system is composed of:
- a liquid supercooler
- expansion valve
- solenoid valve
- sight glass
- filter dryer
The two possible variants of the HGZ7:
1. Standard design
Intermediate pressure line mounted and insulated
Liquid supercooler, expansion valve, solenoid valve, two sight glasses, filter dryer everything enclosed separately for individual, external mounting.
2. Optional design
Liquid supercooler, expansion valve, solenoid valve, two sight glasses, filter dryer attached directly to the compressor, lined and insulated.
