Introduction
The PolyScience line of 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.
Standard and Optional Features
DuraChill Chillers offer 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 broad range of process cooling applications.
These powerful Chillers can be configured with a wide variety of standard and optional features, including:
Standard Features
• Process temperature range: 32° to 86°F (0° to 30°C)
• Ambient temperature range: 60° to 104°F (16° to 40°C)
• Temperature stability: ±2.0°F (±1.1°C)
• High efficiency vertical air exhaust
• Accurate microprocessor control with digital LED readout
• Pump protection by means of a Full Flow Bypass Valve
