Gas chiller NQ series

waterindustrialair-cooled

NQ Series industrial portable chillers use components such as scroll compressors, microchannel condensers, low noise fans, stainless steel brazed plate evaporators, and NQ Series PLC controls with large color touch screens to provide the best available technologies for the ultimate performance and reliability in a chiller package. Overview Control System provides diagnostics and precise temperature control Compact microchannel all aluminum air-cooled condensers for increased durability High efficiency fans (air-cooled units only) with integral condensers feature totally enclosed air over (TEAO) motors for long life Stainless steel brazed plate evaporators with flow and temperature safeties to guard against freezing Reliable and energy efficient scroll compressors Compressor staging for reduced energy use on 20 ton and larger units Compressor , pump and condenser fan starters (air-cooled units only) mounted in control panel and wired to motors Remote 4-20 mA set point temperature input capability for increased application flexibility Low voltage 24 VDC control keeps the control circuit signals free from AC interference Internal insulated polyethylene reservoir Removable inlet air filter (air-cooled units only) is easily cleaned and protects condenser coils to assure maximum efficiency Tools-free removable doors Solid state safety switches with electronic sensing devices Hot gas bypass provides accurate capacity control and extends compressor life Water regulating valve (water cooled units only) keeps refrigerant pressure constant Alarm horn EPA approved low GWP R-454B refrigerant or energy efficient R-410A refrigerant 18 month parts, and 12 month labor warranty
