The Durachill DCA180 Chiller provides reliable heat removal for lasers, EDM equipment, and other precision devices that utilize deionized (DI) water or other coolants with high dielectric properties.

Capable of maintaining process temperatures from 41°F to 95°F (5°C to 35°C) with ±0.9°F (0.5°C) stability, it incorporates PolyScience’s advanced Cool Command™ refrigeration technology to provide effective cooling even at elevated temperatures without excessive energy consumption. A choice of either a centrifugal or a turbine pump helps further optimize cooling efficiency and performance.

For operational and process safety, the DCA180 features alarms that alert you instantly when operating parameters — such as fluid temperature, flow rate, fluid pressure, or ambient temperature — exceed pre-set limits. In addition to the built-in compressor and pump protection, there are even user-adjustable high and low temperature limits to help prevent unauthorized set point changes.

This compact unit features an easy-to-use calibration function that allows you to adjust the chiller’s temperature display to match a traceable temperature standard. Heavy-duty locking casters and a power phase monitor on 3-phase models are standard. Options include interfaces for various control functions, such as remote control, remote ambient temperature tracking, and conductivity control.
