A line of portable chillers with variable-speed compressors has been extended to include 30-ton units.
Accuchiller NQV, manufactured by Thermal Care, is designed to provide energy savings for processes where the heat load regularly varies. An NQV uses a variable-speed compressor and a PLC to constantly monitor the heat load and adjust the compressor speed for peak efficiency and temperature control. As a results, Thermal Care says, the chiller works only as hard as necessary to provide optimum performance with reduced power use.
Company testing has shown energy savings of up to 51 percent using a NQV chiller as compared to a conventional portable chiller.
According to Thermal Care, customers asked the company to increase the size range of the NQV product line because of its cost effectiveness. NQV series portable chillers are available from 5 to 30 tons in both air-cooled and water cooled models.
