Product description
The PRO RP 290 E circulation and process thermostat provides heating and cooling for external applications with rapid temperature response. Low filling volume enables fast temperature changes in the connected system. The compact tower design reduces footprint while an integrated cooling coil and hybrid cooling options (ambient air and cooling water) support demanding temperature control tasks. The unit is equipped with a LAUDA Varioflex pressure/suction pump for process circulation.
