  • CE approved (50 Hz)

The PolyScience 3370 recirculating coolers are liquid-to-air; they continuously pump near-ambient temperature water from a reservoir to an external heat source, through a cooling radiator, and then return cooled water to the reservoir. By blowing ambient air over the radiator, water flowing inside is cooled and the heat is exhausted into the atmosphere.

PolyScience 3370 Recirculating Coolers Feature:

  • An economical cooling solution for applications where cooling fluid temperature is higher than ambient and temperature control is not required
  • Quiet liquid-to-air cooling
  • Positive displacement or turbine pump
  • Built-in low liquid level indicator

Applications for PolyScience 3370 Recirculating Coolers

  • Bioreactor temperature maintenance
  • Transfer heat from valuable equipment: CCD camera, spectrophotometer, densitometer, condenser, lasers etc
  • Inductively Coupled Plasma overheating prevention (turbine pump recommended)
