Process thermostat PRO RP 250 EC

compactdigitalelectronic

Product description
The PRO RP 250 EC thermostatic circulation unit provides integrated heating and cooling for external applications with a working range from -50 °C to 200 °C. Its low filling volume enables rapid temperature changes. The compact tower design allows space-saving installation. An integrated cooling coil and hybrid SmartCool refrigeration enable cooling via ambient air or additional cooling water. The unit is equipped with a pressure-suction LAUDA Varioflex pump and a detachable command console for remote operation.
