F33-HL Refrigerated/Heating Circulator
Superior models for most demanding applications
JULABO Refrigerated & Heating Circulators for heating and cooling are
suitable for external temperature tasks and for temperature applications
directly in the bath. A model from three different series’ with different
capacities can be selected. Powerful circulating pump systems and high
heating and cooling capacities guarantee short heat-up and cool-down
times. The inevitable dust accumulation that occurs in refrigeration systems
is solved by means of an easily removed venting grill, which allows for easy
cleaning. Depending on the model, 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. The compact assembly of each unit
enables a space to be saved in the laboratory.
