JULABO Ultra-Low Refrigerated Circulators for heating and cooling. The units are suitable for external temperature applications with simultaneous operation in the bath tank. The units provide particularly high heating and cooling capacities for rapid heat-up and cool-down times even for large volume, external systems. ‚FP‘ models offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment. Models with the designation ‚W‘ are water-cooled. With handle or castors to allow easy transport. With drain port for conveniently draining the bath fluid. The units offer an improved insulation to prevent ice-formation and have a filling level display. Typical applications: Temperature applications to jacketed reaction vessels, autoclaves, miniplant installations, kilo labs, freezing point determination, calibration at low temperatures, petroleum testing, etc.
Ultra-low Refrigerated Circulator with 2-stage cascade-cooling
JULABO Ultra-Low Refrigerated Circulators for heating and cooling are suitable for external temperature tasks. Powerful circulating pump systems and high heating and cooling capacities guarantee short heat-up and cool-down times. ACC ‘Active Cooling Control‘ provides active cooling control across the whole temperature range. An energy saving feature with only minor loss of heat is provided by the proportional cooling capacity control in the ‘FP’ refrigeration units. The inevitable dust accumulation that occurs in refrigeration systems is solved by means of an easily removed venting grill, which allows for easy cleaning. 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.
