For decades, cooling towers have provided an efficient means of cooling industrial process loops by providing the lowest operating temperatures available. At the same time, through the years, water-based cooling systems have evolved. 

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 applications requiring high water-cooling performance in small spaces, the mRC-Kit-900-Twin provides two independent water-cooling systems that can provide a combined maximum cooling capacity of 900 W in a 19” rack-mount insert.

When sizing, selecting and installing hermetic pumps in refrigeration units, there are many considerations. This article will explore the types of pump as well as provide a guide for troubleshooting common problems.

EarthSmart ESTW Series eliminate the constant water consumption and treatment requirements of conventional evaporative towers, utilizing closed-loop cooling that isolates process water from contamination. 

Many applications require water for cooling. Rotary evaporators, microscopes and spectrophotometers found in the laboratory can require cooling water. Industrial-scale applications such as semiconductor, additive manufacturing and extraction processes also typically require water for cooling. 

Line of -40 and -76°F (-60°C) portable chillers is equipped with on-board diagnostics that help predict chiller health and avoid unexpected downtime.
