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Note: In 2014, this chiller had a major maintenance and the existed RC 4-12 Grasso compressor has been replaced by a Grasso/GEA V1400 package.
