F81-ME Ultra-low refrigerated / heating circulator

Ultra-low refrigerated circulator with 2-stage cascade-cooling

The ultra-low refrigerated circulators of the TopTech series are equipped with a dual-stage cascade refrigeration system for continuous operation of internal and external temperature applications.

Models with ME circulator

  • Heated bath cover plate to prevent condensation or ice build-up
  • Pressure pump up to 0.45 bar, electronically adjustable in steps
  • ACC Active Cooling Control across the entire temperature range
  • Compact design Note: FP models feature an energy-saving proportional cooling control.

Performance data depends on the mains voltage in the country of use. Please select:
