JULABO refrigerated and heating circulators are suitable for temperature applications to external systems with simultaneous operation inside the bath tank. Models in different performance classes – CORIO, TopTech, DYNEO and HighTech – fit any challenge and budget.


JULABO GmbH
Working temperature range: -50 to +200°C
Heating capacity: 2 kW
Cooling capacity (at 20°C): up to 1 kW
Pump flowrate: up to 27 liters/min
Pump pressure: 0.1 - 0.7 bar

JULABO Refrigerated and Heating Circulators are suitable for temperature application to external systems with simultaneous operation inside the bath tank. The units provide high heating/cooling capacities to ensure rapid heat-up and cool-down times. ‚FP‘ models offer proportional cooling control to ensure energy-saving performance and to reduce heat generation to the environment. All models provide a drain port on the front for conveniently draining the bath fluid.

Applications: Temperature applications to external, closed systems, such as photometers, refractometers, viscometers. Suitable for simultaneous application to small objects in the circulator bath.

Models in different performance classes – CORIO, TopTech, DYNEO and HighTech – are available. More info

The CF series offers compact refrigerated/heating circulators. Thanks to their compact design, the units can be placed on very small surfaces or within a complex installation. All models are safety class 3 according to DIN12876-1. The maximum ambient temperature of +40°C as well as a ventilation air cooling allow installing the units very closely side by side with other units or directly under a fume hood. All models feature pump connections for external temperature applications and a bath opening for temperature control of small objects directly in the circulator bath. Wetted parts are made of high-quality stainless steel or plastic. The instruments provide a reliable microprocessor electronics with high temperature stability as well as warning and safety functions. More info
