Heavy-Duty Air Heaters

Features

These high-temperature, moderate-volume air heaters are designed for continuous high-temperature operations up to 1200°F while supplying a good flow rate up to and in excess of 50 CFM. This kind of heater is especially suited for vacuum and pressure environments, as well as other applications where a heavy-duty construction is desirable. Design features include a nickel-chromium heating element supported inside of a high quality ceramic core. The outside sheath is stainless steel with heliarc welds and fittings. The terminals are a high-quality ceramic-to-metal especially designed for heavy loads and high pressures.

  • Designed for high volume and high temperatures
  • Pressure rating: 100 PSIG at room temperature – higher pressure ratings are available
  • Made in the USA

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
