Description / remarks: 

Used Grasso/GEA industrial water-cooled water chiller type FX GC PP 1850-2-DUO-NH3. This in very good maintained condition industrial water-cooled water chiller is equipped with the following on frame-built main components:

  • 1 piece Grasso 612-E piston compressor, built 2004 with a direct driven 200kW Schorch E-motor 1480 RPM
  • 1 piece Grasso V1400 piston compressor, built 2014 with a direct driven 250kW WEG E-motor, controlled by a frequency controller up to a maximum speed of 1200 RPM
  • GEA plate heat exchanger/evaporator type LWC 150L BT-16 coupled to a EM Polar separator for natural ammonia circulation
  • GEA water-cooled condenser  type LWC 150L B-25
  • HS-Cooler heat exchanger in the discharge line of the compressors for hot water supply (heat recovery)
  • All associated water pumps, brand Grundfos
  • Switch-board cabinets with Siemens S7 PLC / Simatic touchscreen
  • All required certificates

The mentioned cooling capacity of 1240kW is with a water/freezium mixture of 29% at a water/freezium range of -0,5°C/-5°C with 257 m3/h and a water/freezium range of -4°C /-8°C is 1080kW with absorbed power 260kW.
Cooling capacity at a water/freezium range of -0,5°C/-5°C with 234,5m3/h is 1170kW with absorbed power 296kW and at a water/freezium range of -4°C /-8°C is 985kW with absorbed power 281kW.

Note: In 2014, this chiller had a major maintenance and the existed RC 4-12 Grasso compressor has been replaced by a Grasso/GEA V1400 package.
