About Liquid Chillers

Benchtop Liquid Chillers

Send cool water to equipment right from your bench top without compromising precision. These chillers maintain constant, uniform temperatures within 0.2° F where other chillers only keep liquid cool within a few full degrees. This makes them ideal for equipment where small temperature changes could cause an issue, such as microscope cooling plates.
Fill these chillers with water or glycol solutions, and an internal pump moves the liquid through a cooling system and out to your equipment. Use the built-in keypad to manually set the temperature, or connect an external controller of your own to automate temperature changes. View the set temperature, alerts, and other information from the LED display.
Chillers rated for 500 Btu/hr. are also known as Peltier chillers. They cool liquid using electricity—no need for compressors or refrigerants. Because they don’t use a compressor, you’ll hardly hear them when they’re on. To check fluid levels at a glance, their tank inlet is semi-clear.
