  • Can you explain the Flameless Design?

    Flameless by design refers to the fact the heat source was designed to be flameless, which it is.  The GT 1400 has NO external or exposed flame. At the heart of the GT 1400 heater is a small micro-turbine that runs on ordinary pump Ultra Low Sulfur Diesel or ULS Kerosene fuel . The GT 1400 heater is an internal combustion Micro Turbine jet engine. The combustion takes place entirely within the confines of the combustion chamber similar to a reciprocating piston engine. Like your car, there are no exposed flames.

  • Can you explain Direct Fire vs. Indirect Fire?

    Direct fire units force air directly through the flame to heat the air. The burner fires directly in the air stream being heated rather than through a heat exchanger. This results in no wasted energy by these types of commercial heating units and 100% of available energy is delivered to the heated space because no flue or heat exchanger is required. With heaters using Indirect fire the flame is contained in a burn chamber which heats a heat exchanger.

  • Can you explain what you mean by “BTU Equivalent”?

    Heat energy for diesel burned provides 138,000 btu/gal. JetHeat uses the term “Btu Equivalent” when rating our heater to illustrate that our heater produces as much or more heat than any competitive heater while consuming half of the fuel.  Another way of looking at it is that our input and output BTUs are virtually identical, whereas our competitors produce output that’s approximately 50% of their input.

  • How does the Catalyst work?

    The catalyst works like an automotive catalytic converter which converts CO to C02  The JetHeat unit uses a very specialized fuel system that turns the diesel into vapor before combustion.  Therefore there are no ‘fuel droplets’ to burn, only gaseous fuel.  Unlike a conventional diesel engine, this vapor burns cleanly and completely resulting in low emissions and virtually no soot.  You won’t see black smoke come out of a JetHeat like you see on a conventional diesel unit.

  • How often does the Catalyst need to be replaced, and what happens if it fails?

    The catalyst doesn’t really fail; it degrades over time.  As it degrades the conversion from CO to CO2 will likewise degrade resulting in higher CO emissions necessitating washing and ultimate replacement of the catalyst if required.   Following our User Guide recommendations will result in safe operation and a catalyst that can be used for multiple seasons.

  • The video states the equipment has to be upwind of emitted hydrocarbons, what happens if it ingests these fumes?

    Our heater is a clean-air heater if it draws in clean air….no different than our competition.  We recommend placement not to draw in emitted hydrocarbons (dirty air) so the output remains clean.  Ingesting hydrocarbons has no detrimental effect on our heater.   While our video appears to make this a requirement, it is really just a suggestion.

  • What does 180 degrees Temp rise refer to? Is it the temperature at the outlet?

    180 degrees refers the temperature rise from the ambient temperature of the mixed outlet air.  We make really hot air in really cold conditions immediately!

  • What happens if the ducting is bent or at a 90 degree angle?

    The point is to minimize back pressure to optimize the performance.

  • There is a built in RPM limiter used to stop the gas turbine during runaway conditions. How does this stop the engine?

    The computer monitors RPM 200 times per second.  If the computer sees RPM levels outside of set parameters it will trigger a rapid shutdown.
