FPW52-SL-150C Ultra-Low Refrigerated-Heating
Circulator
Superior models for most demanding applications
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.
