A liquid-to-liquid temperature control unit designed for multiapplication cooling has been introduced by PolyScience. The Model 426 provides secondary zone temperature control when attached to a primary cooling source such as tap water, cooling towers, central fluid cooling systems or a single recirculating chiller. The company says that the unit offers excellent stability of fluid temperature because of a unique combination of microprocessor control and a direct injection valve. The compact system has a temperature range of <3 °F above source water to 180 °F, with stability of ±0.1 °F. It offers 2000 W of cooling capacity at 68 °F and a nominal flow of 3.5 gallons per minute, and it uses standard 1/2-in. NPT connections.
