Features on all Polyscience Refrigerated Circulating Baths


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.


Alpha-numeric message bar guides you through setup and provides important operational information. For further optimization of temperature control, you can easily input the specific heat capacity value for the heat transfer fluid that you’re using.
