Patented WhisperCool® technology reduces overall equipment noise, increases refrigeration efficiency and lowers energy consumption.

Enery 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 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.


An ISO 14001:2004 compliant Environmental Management System, a WEEE-compliant recycling program and RoHS-compliant manufacturing are just some of the green initiatives PolyScience has undertaken to minimize our impact on the environment.

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.
