INDIRECT LINE HEATERS

(Also known as “line heaters”) Energy, in the form of heat, is transferred from a submerged fire-tube wall into bath fluid which is transferred into process coils via convection. Indirect fired heater temperatures tend to be lower than other heaters and are atmospheric, with an expansion tank to compensate for change in bath fluid density with varying bath temperatures.

More about Indirect Line Heaters:

  • Process bath heaters have few moving parts, require very little maintenance, and can achieve efficiencies of 70% without the use of an economizer.  Indirect fired heaters designed for hazardous area classifications and control system components meet CSA, NFPA and UL recommendations.
