Wattage calculation and heater selection

For applications with input temperatures below 120°F, you can find the required wattage quickly by plugging the flow rate (Rflow, in SCFM) and temperature rise (ΔT, in °F) into this formula:

Required kW = Rflow • ΔT3,000 • 1.2

For detailed background on selecting a heater, see the article in the box on this page. To order, select from the table below to go to an ordering page.
