GEA Grasso chillers for high evaporation and condensation temperature difference

By Silvia Scaldaferri, Nov 17, 2014, 11:05 1 minute reading

The GEA Grasso FX P and GEA Grasso FX Pduo chiller series, developed and supplied by GEA Refrigeration Technologies, are leading the market for industrial freezing and heat pump applications. The ammonia-based chillers achieve high levels of efficiency, require low refrigerant charge and are not damaging to the environment.

GEA Refrigeration Technologies offers a wide range of chillers suitable for industrial cooling as well as industrial air conditioning.

Specifically designed to satisfy the needs of industrial applications exhibiting a large temperature difference between evaporation and condensation, GEA Refrigeration Technologies has developed the following series of chillers:

  • GEA Grasso FX P
  • GEA Grasso FX Pduo

Both product ranges achieve optimum TEWI (Total Equivalent Warming Impact) values as they operate with ammonia refrigerant (R717), which has zero GWP (Global Warming Potential) and zero ODP (Ozone Depletion Potential).

Applications for the GEA Grasso FX P and GEA Grasso FX Pduo

GEA Grasso FX P and GEA Grasso FX Pduo can be used for both freezing and heat pump applications with capacities between 200 and 5,800 kW. The chillers are also suitable for condensers in water-cooling, air-cooling and evaporative applications.

The difference between the two product ranges is that the FX P uses a single screw compressor whilst the FX Pduo uses two screw compressors operating in parallel,

Combining minimum refrigerant charge with high operational efficiency

Both the FX P and the FX Pduo comprise of an expansion control system that ensures minimum refrigerant charge and high operational efficiency, namely on the frequency converter.

Key characteristics:

  • Flooded expansion
  • Plate heat exchanger as evaporator
  • Electronic injection system
  • Electronic system control
  • Low final compression temperatures, also with high-pressure conditions
  • Economizer as an option
  • Variable speed drive as an option
