Ultra-Low Refrigerated Circulators, JULABO

JULABO ultra-flow refrigerated circulators for heating and cooling are suitable for external temperature applications directly in the circulator bath. Powerful circulating pump systems and high heating an cooling capacities guarantee short heat-up an cool-down times even for large-volume, external consumers. An energy saving feature with only minor loss of heat is provided by the proportional cooling capacity control on the FP models. Models with the type suffix "W" are water-cooled. The units are equipped with handles or castors for an easy transportation. All models have a drain tap on the front allowing the fluid to be drained easily. Additionally the instruments are equipped with an improved insulation to help avoid ice-formation, and have a visual liquid level display. Typical applications are the temperature control of double-walled reaction vessels, autoclaves, miniplant systems, kilo laboratories, freezing point determination, low temperature calibration, petroleum tests, etc.
