Mini Clean Flow - Large DI Water Heater:
  • Temperature from 18°C to 66°C in 2 hours
  • 316 Stainless Steel All wetted parts
  • Pressure tested to 90 PSI
  • NEMA 4 Housing
  • RTD, 3-wire 100 ohm process sensor built-in near outlet
  • An additional TC for bottom temperature read
  • 16KW (± 10%), 208 Volt, 3-phase
  • Mounting threads on the bottom of the assembly
  • Medium being heated: Deionized Water (DI Water)
  • Recirculate at 3gpm


The heater zones were individually heated at lower voltage then pressure tested up to 90 PSI at 20°C - 25°C. The typical ramp temperature for a bench test prior to shipping is 100°C. The response time in an air medium environment was immediate as the temperature was achieved in under 20 minutes. All zones passed the recommended 700 VDC for 5 seconds on the Hi-Pot test prior to shipping. The heater was cleaned & packaged then sent out for delivery.
