Chiller, Air (156SK - 527SK)
Central Chillers
The Conair Air-Cooled A-SK series Central Chillers are engineered to meet the most demanding needs of plastic processors. The modular microprocessor control coordinates the actions of the chiller and provides stand-alone operation of the units. These chillers are space conscious. Units can be positioned as close as 4 ft. {1.2 m} from a vertical wall.
