Accuchiller NQV Series
5 to 30 Ton Chillers with Variable Speed Scroll Compressors
Portable & Packaged Chillers
Same great features as the NQ Series portable and packaged chiller with the addition of an optional variable speed compressor for significant energy savings!
NQV Variable Speed Chillers with advanced NQ Series PLC Controllers are at the technological forefront of the process cooling industry. The controller constantly monitors the heat load and adjusts the compressor speed for peak efficiency and temperature control and eliminates the need for hot gas bypass. By automatically adjusting the compressor speed, the chiller works only as hard as necessary to provide optimum performance with significantly reduced power use. Studies have shown that a 20% reduction in motor speed can lead to a 51% energy savings.
