The units are extremely simple to operate, easy to install and maintain, and will provide years of reliable and accurate heat removal.

PolyScience Refrigerated/Heated Circulators come with the following accessories:

  • Reservoir cover
  • Bypass tubing
  • Male inlet and outlet adapters for 3/8, 1/4, and 3/16" (.95, .63, and .47 cm) tubing. 1/4" to M16 adapters also included on 50 Hz units.
  • 6' (1.83 m) standard grounded electrical cord with country-specific plug
General Features
Proprietary patent-pending WhisperCool™ technology reduces overall equipment noise, increases refrigeration efficiency, and lowers energy consumption.
Easy to maintain
Accessing the reservoir drain and removable air filter for maintenance is as simple as removing the circulator’s front panel. Performance Programmable, Advanced Programmable and Performance Digital models even remind you when it’s time for filter cleaning.
Energy saving
Cool Command™ technology carefully regulates the amount of cooling required, saving energy while delivering fast cool-downs and more precise control at elevated temperatures.
All models feature user-settable high-temperature safeties as well as redundant over-temperature protection and comply with RoHS, WEEE, IEC 61010-1, IEC 61010-2-010, IEC 61326-1, DIN 12876 and are CE and ETL certified. Our DuraTop™ surface is cooler to the touch when operating at high temperatures.
Whether equipped with the entry-level controller or the most sophisticated, PolyScience Refrigerated/ Heated Circulating Baths are extremely easy to use. Clear navigational buttons and menu prompts guide you through setup, making operational and temperature set-point changes simple and precise.
