JULABO Refrigerated and Heating Circulators are suitable for temperature application to external systems with simultaneous operation in the bath tank. Models in different performance classes are available. The units provide high heating/cooling capacities to ensure rapid heat-up and cool-down times. With ‚Active Cooling Control' to +200 C (not on ED models). ‚FP‘ models offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment. Convenient cleaning of dust by removable venting grid. Some models have a handle or castors to allow easy transport. All models provide a drain port on the front for conveniently draining the bath fluid. Typical applications: Temperature applications to external, closed systems, such as for example photometers, refractometers, viscometers, etc. For simultaneous application to small objects in the circulator bath.
