Water-Cooled Condensers - HTS

IntroductionThe WGS water-cooled screw chillers continue McQuay International’s legacy of high quality, highefficiency, latest technology and quiet operation. Our model WGS units utilize an advancedcompressor design utilizing R-134a refrigerant. Superior control is provided by the innovativeMicroTech II family of controllers. Interface with your building’s automation system with theDaikin McQuay Open Choices feature using factory-installed LONTALK, BACnet orModbus communication modules. The WGS chiller continues to be the ONLY screw compressorchiller on the market with superior solid state starters as standard equipment. Perhaps mostimportantly, they continue McQuay’s reputation for quiet operation making these chillers “buildingfriendly”.The WGS solid state starters provide stepless acceleration, controlled deceleration,and advanced motor/compressor protection features. McQuay International is theonly manufacturer to provide this advanced technology as standard equipment onwater-cooled screw chillers.SUPERIOR EFFICIENCYSingle-rotor compressor designElectronic expansion valve controlHigh efficiency single-pass direct expansion evaporatorAll models exceed ASHRAE 90.1-October 2001 efficiency standardQUIET OPERATIONSingle rotor design is inherently quietVirtually vibration-free operationOUTSTANDING RELIABILITYIndependent refrigerant circuitsRugged compressor designSolid state starters for smooth acceleration and decelerationAdvanced composite gaterotor materialMultiple compressors with independent controllersProactive control logicFull factory package unit run-testing to optimize trouble-free operationFactory authorized startupSUPERIOR CONTROL LOGICEasy to read 4-line by 20-character LCD displaySupports standard protocols: LonTalk, BACnet or ModbusSuperior reliability under extreme operating conditionsCatalog WGS-1 WGS 130A – 190A 3
