Flow Torches

Flow 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 low pressure (and economical) blowers
  • Support high volume air flow
  • Heat air up to 482°C (900°F)
  • Fast heat up and cool down due to low mass open coil design
  • Can be connected to suitable flexible duct or pipe fittings
  • All Flow Torch Heaters are UL recognized components under UL file number E365755.

Farnam is developing several graduated sizes of this basic platform. This family of heaters is offered as a standard product with several options. Farnam offers application assistance so you can best match the heater to your requirements and needs. Control packages are available. Pressure Drop Charts are available for quick comparison.

 

Flow Torch™ 200
 
  • The Flow Torch 200 is a 2" diameter stainless steel air heater designed for high flow rates at low pressure drops. It incorporates an open coil spiral wound element of the highest grade material which provides quick heat up and cool down cycles with maximum heat transfer.
  • The Flow Torch 200 is capable of operation with airflows of up to 115 SCFM and up to 120 PSIG. Maximum output temperature is 900°F (482°C). Standard power of 1 kW to 10 kW is available in 500 watt increments.
  • The Flow Torch 200 offers reliable, long-life performance and reduced operational costs. Applications include hot air curtains, air drying, baking, chemical processing, dehumidification, laminating, web drying, textile applications, ink drying, paint baking/ drying, plastic curing, metallization, exhaust gas heating, hopper drying and sterilization. Optional equipment includes thermocouple and thermocouple fittings, stainless steel inlet and outlet reducers for hose or pipe. Control Panels are also available to provide precise temperature regulation.
