High temperature heating circulator PRO RP 250 EC

Product description
The PRO circulation and process thermostats are designed for external applications and are specified for high-temperature operation; see technical data for the operating range. Low filling volume enables rapid temperature changes in the connected application. The compact tower design reduces footprint. An integrated cooling coil is fitted as standard for counter-cooling. All models include a pressure/suction pump. Hybrid cooling of the refrigerating system permits cooling by ambient air and, where required, additional cooling water.
