Price RangeCall for Quote


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 is provided by the proportional cooling capacity control in the ‘FP’ refrigeration units.
The SL circulator controller with dual VFD and LCD digital displays includes a keypad for easy data entry. The integrated programmer enables saving of 6 x 60 program steps and also includes a RS232 port for external PC communication and Pt100 port for external temperature control / monitoring.
An adjustable centrifugal pressure / suction pump with flow rate from 22-26 L/min; pressure flow 5.8-10.2 psi; suction flow 2.9-5.8 psi. M16x1 male pump connections with 8 and 12 mm hose barbs. The Smart Pump function automatically adjusts pump rate to compensate for increases in fluid viscosity.

Included with each unit: 2 each barbed fittings for tubing 8 and 12 mm inner dia. (pump connections M16x1 female).
