In this technical note, we explore three causes of thermal instability and the solutions that modern recirculating chillers can offer to laser manufacturers. Specifically, we describe the in-field problems that users encounter — and create — when operating a laser system. The prevalence of these problems inspired the creation of the PolyScience DuraChill® line of chillers.

For five decades, PolyScience has responded to the needs of laser, laboratory, chemical, medical, industrial, and plastics markets with unparalleled innovation, passion and user-focus. Our dedication to quality, ease of operation and reliability has helped us become a global company that spans six continents.

Our Refrigerated Circulators, Heated Circulators, Chillers, Recirculating Coolers, Water Baths and special-purpose products are designed to simplify tasks, take less space, integrate more seamlessly and perhaps most important, make your work productive and enjoyable.

PolyScience can help you configure a user-friendly recirculating chiller for every one of your applications. If you submit the specifications for your system’s laser head, we can calculate the ideal pump, fluid, and power capacity for your new chiller. Moreover, we can work within your budget to specify a chiller that will provide your customers with the highest value.
