High temperature heating circulator PRO RP 250 E

refrigerated

Product overview
The PRO RP 250 E is a heating and cooling circulation thermostat for external process applications. It features a low filling volume for fast temperature response, an integrated cooling coil and hybrid condenser cooling (air and cooling water). The unit is designed for compact, space-saving installation and external tempering tasks with a working range covering deep sub-zero to elevated temperatures.
