CHA/FC 642÷2204AIRCOOLEDLIQUID CHILLERSLFREE-COOLING WITHAXIAL F ANS, SEMI-HERMETIC COMPRESSORS ANDSHELL L AND TUBE EXCHANGERS.FROM 165 kW TO 600 kW.UNIT DESCRIPTIONThe <strong>water</strong> coolers of the CHA/FC 642÷2204 series offer innovativetechnology to meet the needs of large systems for both domestic aswell as industrial applications requiring the production of cooled<strong>water</strong> continuously year-round.During the cold months, in the FREE COOLING operation mode,the return liquid of the system is cooled directly by forced convectionof outdoor air through the condensation battery, thus savingenergy by not operating the <strong>unit</strong>’s semihermetic compressors. A 3-way valve system controlled by the electronic microprocessor controllerthat manages the entire <strong>unit</strong> allows, based on the temperatureof the outdoor air, operation in CHILLER L or FREE COOLINGmode. The product range includes 13 models composed of versionswith tank, with pump or with tank and pump.VERSIONSCHA/FCCooling onlyFEATURES• Self-supporting galvanized steel frame protected with polyesterpowder painting.• Semi-hermetic compressors type complete with cranckcase heater, oilsight glass, incorporated thermal protection and shut off valves.• Axial fans directly coupled to a 3-phases electric motor with externalrotor.• Condenser made of FREE-COOLING copper tube and aluminiumfinned coil.• Shell and tube type evaporator, with two indipendent refrigerantscircuits and one <strong>water</strong> circuit.• R407C refrigerant.• Electrical board includes: main switch with door safety interlock, fuses,overload protection for compressors and thermocontacts for fans.• Microprocessor control and regulation system.Factory fitted accessories:ACCESSORIESPD Double circulating pumpSPU Inertial tank and single circulating pumpSPD Inertial tank and double circulating pumpMF MufflerRF Cooling circuit shut off valvesSS Soft startCP Potential free contactsLoose accessories:MN High and low gaugesMO Compressor oil gaugesCR Remote displayISRS 485 serial interfaceRP Metallic guards for condenserAGRubber shock absorbersAM Spring shock absorbersFL Flow switchIMSLHRT/PSPPUProtection moduleUnit silencementTotal heat recovery in parallelInertial tankSingle circulating pump54
