Heated circulator PRO RP 245 E

Overview
The PRO circulating heating and process thermostats are designed for external applications and specified for temperatures up to 250 °C. Their very low fill volume enables rapid temperature changes on the connected application. The compact tower design minimises required floor space. A factory-integrated cooling coil is available for counter-cooling. Cooling models offer quick temperature transitions thanks to cooling capacities of 0.6 and 0.8 kW combined with the small fill volume. All units include a pressure-suction pump and a hybrid refrigeration system permitting air or additional water cooling.
