AIRCRAFT COMBUSTION HEATERS & FACTORY NEW PARTS

Superior Durability, Reliability, & Serviceability.

Hartzell Engine Technologies (HET) is the leading OEM supplier of aircraft cabin heating solutions and engine accessories. During cold weather operations we have been the reliable source of combustion heaters for over fifty years.

I-Series Aircraft Cabin Heaters directly replace Janitrol branded B-Series heaters & are exempt from any AD.

HET is proud to announce it's newest combustion heater line now available for general aviation aircraft, introducing the I-Series aircraft heater. Adapted from its proven military applications, the I-Series is the only A.D. free heater on the market featuring innovative combustion tube technology fabricated from Inconel®. This material provides substantially improved performance over ceramic coated material currently used in other heaters. Compared to coated stainless steel, the advanced design of the I-Series heater has significantly improved protection in extreme temperature applications.

 

I-SERIES AIRCRAFT CABIN HEATER

  • Features a combustion tube fabricated from Inconel® material, which provides improved protection from oxidation vs. stainless
  • No AD Restrictions
  • First to introduce the "Whirling Flame" principle of combustion
  • Adapted from Military Applications with thousands of heaters produced and successfully performing in the field
  • Reliably ignites at temperatures down to -65º F
  • NEW or FACTORY REBUILT 
    Only Hartzell can provide rebuilt Janitrol heaters to new specifications
  • FAA-TSO Approved
  • 36 month, 1000 hr. Full Warranty
    (Not pro-rated) on Typical System Components
  • 2000 hr. TBO
  • Replaceable Spark Plug with Ground Electrode

Each heater system consists of a heater assembly, a ventilating air blower, a combustion air blower, nozzle holder, solenoid valve assembly, new spark plug, high voltage ignition system, combustion air pressure switch, overheat switch, cycling switch, and necessary radio noise suppressors. Optional equipment includes a duct switch, fuel pump, fuel regulator and shutoff valve, combustion air blower inlet adapter and a fanning strip (connectors). All components except the combustion air blower, duct switch, fuel regulator and shutoff valve and fuel pump are combined into one assembly to facilitate installation and service operations. The optional equipment items are provided as separate components since they maybe mounted at different locations in the aircraft.

 

Combustion chamber flame tests show the efficient clean and central burn of the I-Series Heater tube, which results in improved durability and reliability.

Camera was oriented such that it was looking down the combustion tube from the end cap position towards the igniter and fuel nozzle. The igniter arc was a reference point for the center of the combustion chamber. Flame tests exposed the I-Series heater tube to cyclical 1800 and 2000ºF.
