Copyright 2010 Carrier Cor poration Form 23XR V -3PD Carrier’ s Ev ergreen ® 23XR V chiller is the world’ s first integ rated v ariable speed, water-cooled, screw chiller .
2 V ariable speed capacity control elimi- nates slide valves, their associated loss- es, and their potential failure modes. Component count (both rotating and total) has been minimized assuring maximum relia bility under a wide range of operating conditions.
3 • Machine room cooling re quirements associated with air-cooled motors, which dissipate heat to the mechan- ical room. • High noise levels common with air- cooled motors, which radiate noise to the machine room and adjacent areas.
4 feature also allows the machine to operate at reduced capacity, rather than shut down, when key safety limits are approached. Chilled liquid rese t — Reset can be accomplished manually or automatical- ly from the building management sys- tem.
