Temperature Control Unit | Water Circulating | Up To 300°F

Temperature Control Unit | Water Circulating | Up To 300°F

SRT-1680-300
  • Water temperature control units are engineered to provide precise fluid temperature control over a wide range of applications.
  • These units are used to preheat industrial processes to the desired operating temperature by recirculating water through the process and engaging the unit’s electric immersion heater.
  • After reaching the operating temperature, the unit can continue to add heat or become a cooling device by precisely exchanging & mixing cooling water (supplied from an external source) with the recirculated water to maintain tight temperature control.
  • This temperature control unit requires a plant water supply source.
  • Temperature control units are portable, built on casters to easily move the unit between processes.
  • Temperature range for these units is 32°F to 300°F.
