Chillers & Heat Pumps GEA RedAstrum

Top performance, minimum footprint

GEA RedAstrum is a new series of standard ammonia heat pumps developed for an increasing demand of efficient heating solutions.

This new generation consists of four heat pump models based on the GEA Grasso M screw compressors newly developed for 52-bar applications.

With GEA RedAstrum heating water can be generated at temperature levels between 55 and 80 °C and used for any industrial processes or fed into a district heating network.

Highlights & Technical Features

  • Optimum performance
  • Compact footprint, comes in one piece
  • Heating capacity between 1 and 2 MW
  • Hot water temperature up to +80 °C
  • Heat source between +10 and +40 °C
