Mini Clean Flow – High Pressure

Mini Clean Flow Heater – High Pressure


The BCE application required a custom heating solution at 0.25 CFM with an operating temperature of 800°F (427°C) and an inlet pressure of 800 PSI. The medium being heated was nitrogen. Stainless steel (such as 316) and nickel alloy 600 were used for the heat source in this low flow/mid-temp application.


  • Outlet temperature needed to be 800°F (427°C)
  • Inlet needed to withstand 800 PSI
  • Perpendicular configuration with 1/2" tube fittings
  • Hydrostatically pressure tested to 2000 PSI for 1 minute
  • Must pass all electrical tests before and after the 2000 PSI test
  • Ability to place the heater in a vertical flow position if necessary
  • Type "K" thermocouple for additional temperature measurement
  • 300-Watt, 120 Volt
  • Material: 316SS with Nickel 600 Alloy heat source


High Pressure Gauge

After the 2000 PSI test, the MCF heater was tested to 212°F at 1-3 CFM in the lab. We then re-tested it electrically, checking for any abnormal readings. The tests performed were the meg-ohm insulation resistance at 500 VDC and a hi-pot, 700 VDC test. The heater passed with no changes from the initial inspection prior to the 2000 PSI test.

The heater was cleaned, packaged, and prepared for delivery to the customer.
