The compact footprint can yield substantial installation savings by requiring lessstructural steel, concrete, security fencing or architectural screening. The30GXN,R unit is delivered as a complete package for easy installation.A quick start-up is assured onceinstallation is complete, since each30GXN,R unit is manufactured at anISO 9002 listed manufacturing facilityCopyright 2000 Carrier CorporationForm 30GXN-2PD

to ensure quality. In addition, all unitsare factory run tested under full load toprovide reliable start-up.Easy to live withThe 30GXN,R units have a quiet, lowvibration design featuring rotary screwcompression and “aero-acoustic” fansthat reduce sound levels and improvesound quality. Lower sound levels helpavoid the need for costly sound barriersthat may be needed with other screwcompressor chillers. The 30GXN,Rcontrols are fully automatic. Theleaving-fluid temperature is directlycontrolled, and the entering-fluidtemperature is continuously monitoredto detect load and flow changes.This combination (an exclusiveComfortLink controls advantage)provides the most precise temperaturecontrol available. In addition, the30GXN,R units can handle both quickand slow-loading applications. The30GXN,R units use chlorine-freeHFC-134a refrigerant to help protectthe Earth’s ozone layer and your investment. From a service standpoint,the 30GXN,R units offer the followingfeatures: Use of HFC-134a refrigerant, a single compound refrigerant that iseasy to handle, readily available, andnot subject to phase out Mechanically cleanable cooler Twin screw compressors require little routine service or maintenance Easy viewing of suction and discharge pressures and temperaturesusing either standard or accessorydisplay moduleRotary screw compressionCarrier chillers utilize the CarrierCarlyle 06N Geared Twin screw compressor. Built in a state-of-the-art facilityin Syracuse, New York (U.S.A.), thesethird generation rotary-screw compressors are designed, tested, and built to thehigh standards that are expected fromthe world leader in comfort cooling.Since operating pressures withHFC-134a are about 30% lower thanconventional systems using HCFC-22,internal rotor blowby is reduced, thereby increasing compression efficiencyand reducing chiller plant size. And,since the Carlyle 06N compressor isliquid cooled, it has a low internal pressure drop that makes it ideally suitedfor use with HFC-134a. All 06N2compressors used in 30GXN,R chillersare equipped with the advancedComfortLink Compressor ProtectionModule (CPM). The CPM protectscompressors from phase-loss, reverserotation, over or under current conditions and ground current failures thatcan lead to motor burnout, systemcontamination and costly systemclean-outs.ComfortLink controlComfortLink is your link to a world ofsimple and easy to use air-cooled chillers that offer outstanding performanceand value. The 30GXN,R liquid chillersemploy more than the latest advancedmicroprocessor controls, they utilize anexpandable platform that grows asyour needs change. From stand-aloneoperation to remotely monitoredand operated multi-chiller plants,ComfortLink controls can keep youplugged in.ComfortLink controls are fully communicating, and are cable ready forconnection to a Carrier Comfort Network (CCN). Occupancy scheduling,temperature and pressure readouts,and the ComfortLink handheld Navigator clear language display compliment the standard features, linking youto a world of carefree comfort. The30GXN,R chillers are built on the legendary performance of the Carriermodel 30G Flotronic chiller andshare many of the same time-provenfeatures and technologies providingeasy operation, quick installation andstart-ups that save you money!Superior temperature controlequals potential for greaterproductivityWhether in the classroom, on theproduction floor, or in the office,ComfortLink controls can help you toadapt to changing weather and business conditions. Accurate temperaturecontrol provided by the CarrierComfortLink system helps to maintainhigher levels of indoor air quality, thermal comfort, and productive space.While many air-cooled chillers useonly leaving fluid temperature control,the 30GXN,R chillers utilize leavingfluid temperature control with astandard entering fluid temperaturecompensation. This Carrier exclusiveprovides smart control and intelligentmachine capacity staging. Unlike manychillers, Carrier model 30GXN,Rchillers do not require constant fluidflow. The ability to operate with variable flow also allows building owners torealize even greater overall system energy savings in the chilled water pumping system, and not just at the chiller.Energy management madeeasyWhile 30GXN,R chillers have manystandard features such as network communications capability and temperaturereset based on return fluid temperature, they can also expand as needschange. Supply temperature resetbased on outside air or space temperature is as easy as adding a thermistor.The Energy Management option canallow you to take advantage of changing utility rate structures with easy touse load shedding, demand limiting andtemperature reset capabilities. Resettriggered via 4 to 20 mA signal makesintegrating from an existing buildingmanagement system simple.The 30GXN,R comes standard withthe ComfortLink Navigator display,available with optional remote serviceconnection port, and GFCI convenience outlet (60 Hz only). TheNavigator displays information in aclear language format. The 4-line20-character display can be pluggedinto the unit at either the control panelor at the remote service port. Thisallows the service technician to operatethe unit from where the maintenanceor service work is being performed,minimizing downtime and ensuring thesystem is ready for operation in theshortest amount of time.Features Simple and easy to use ComfortLinkcommunicating controls. Wide operating envelope from –20to 125 F (28 to 52 C). Accurate temperature control withreturn fluid compensation. Built-in dual chiller control, resetfrom return. Superior full and part-loadefficiency. Precise multiple-step capacity. Low noise operation. Dual independent refrigerantcircuits. Full load factory run tested. Wide range of sizes available fromstock. Compact size.
