Introduction
DuraChill Chillers provide cooling power for demanding applications and serve as an economical alternative to tap
water cooling systems. All models feature a microprocessor-based controller, digital Temperature Display (°C or
°F), one-touch set point display, and digital Pressure/Flow Rate Display (PSI, kPa, GPM, LPM) with push-Button
selection. To optimize cooling efficiency and performance, these sophisticated Chillers also feature a modulated
refrigeration system. As a result, temperature stability is greatly enhanced and compressor life extended.
Standard and Optional Features
The PolyScience DuraChill line of industrial Chillers offers exceptional performance, reliability, and operational
simplicity. Available in both air- and water-cooled models, these robust self-contained Chillers are engineered to
provide accurate temperature control in a wide range of process cooling applications. These powerful Chillers can
be configured with a wide variety of standard and optional features, including:
