GEA Bock HG66eThe new 6-cylinder compressor for high capacities and a high level of efficiency

The new 6-cylinder GEA Bock HG66e compressor for high capacities

The new HG66eWith the GEA Bock HG66e series, it is a case of entirely new compressors – these combine state-of-the-art technology with the GEA design features that have been proven for decades. They are equipped with the mexxFlow 2.0 valve plate system and replace the previous 4- and 6-cylinder series HG6 and HG7. MexxFlow is already known and proven in HG88e for its high efficiency and reliability in operation with high capaci-ties. Four sizes cover the range from 116.5 m³/h to 180.0 m³/h displacement (at 50 Hz).

A modern, self-developed valve plate system, the latest generation of electric motors and an improved gas flow in the compressor increase the overall level of efficiency. The proven oil pump lubrication is used in all compressors, and this enables a greater range of speed control to be achieved in the operation of the frequen-cy converter. The emergency running properties have also been optimised - this is particularly important for operation with natural refrigerants. As usual, ease of servicing was one of the main priorities in the develop-ment of the new HG66e compressors: the stators can be changed on site without special tools.

Technical data

All the models of the GEA Bock HG66e series have a

winding section of 50 % / 50 %.

The motor winding is divided into two parts:

partial winding 1 = 50 % and partial winding 2 = 50 %

This winding division reduces the start-up current required for

a partial winding start to approx. 50 % of that for a direct start.
