Pressure Torch™ heaters are highly efficient and ideal for heating large airflows. Some of the advantages these process heaters offer are:

  • Minimal obstruction to airflow (low pressure drop)
  • Ideal for medium pressure (up to 150PSI) blowers
  • Support high volume air flow (up to 2000SCFM)
  • Heat air up to 482°C (900°F)
  • Fast heat up and cool down due to low mass open coil design
  • Connected via flange fittings

Farnam has developed three graduated sizes of this platform as an evolution of our popular Flow Torch product line. This family of heaters is offered as a standard product with several wattage and voltage options. Farnam offers application assistance so you can best match the heater to your requirements and needs. Control packages are available and encouraged for these heaters. Pressure Drop Charts are available for quick comparison. Regenerative Blowers available with complete systems.
