RSCLCondenserless chiller for indoor installationGeneral featuresFRAMESCL/P : self-supporting, galvanized steel frame coatedwith polyester paint.SCL/F e SCL/F…PAC stell frame.COMPRESSORSHermetic “scroll” type with crankcase heater andklixon for overload protection.EVAPORATORSCL/P: braze welded plate to plate type.SCL/F: shell and tube type.Both series are with two independent refrigerant circuitsand one water circuit. The insulation is with a flexibleclosed-cell lining. A differential pressure switch is fittedas a protection which will stop the unit in case there isno water circulation on the plate to plate evaporator.REFRIGERANT CIRCUITEach unit is supplied with one or two independentrefrigerant circuits; each one includes: filter dryer, sightglass, thermostatic expansion valve, service valve.To protect the refrigerant circuit the following devicesare fitted: manual reset high pressure switch, automaticreset low pressure switch, antifreeze thermostat.Besides, only on the size from mod. 111 to 352: manualreset safety pressure switch.ELECTRICAL BOARDIt includes: main circuit automatic breaker switch withdoor locking device, main fuses, compressor contactor ,auxiliary circuits transformer.Microprocessor to automatically control the unit with adisplay to indicate the functions as well as alarmconditions.VersionsDSPartial condensing heat recovery. Each refrigerantcircuit includes a desuperheater insulated and installedin series between the compressors and the condenser.RCSCondensing heat recovery from 70% to 90%. Eachrefrigerant circuit includes: a heat exchanger insulatedand mounted in parallel to the condenser betweencompressor and condenser.RCP100% condensing heat recovery. Each refrigerantcircuit includes: a heat exchanger insulated andmounted in parallel to the condenser and the relevantsolenoid valves.PACAvailable as SCL/F version only. It includes hydraulic kitand storage tank installed on the return line. Thisincludes: insulated storage tank, one or two pumps(one as stand-by), expansion vessel, safety valve, airrelease valve, shut-off valves and, in case of twopumps, non return valve.
