Patron Products USA's 120XD incorporates the latest heat exchange technology with 100 percent clean air discharge for enclosed spaces. Self-contained and towable to the required airfield location, a Hatz diesel provides power for the fan and burner, or alternately 220V hangar power. Dimensioned for 3354 CFM three heat level hot air output, a 12-in diameter hot air discharge outlet will accommodate optional two or three way adapters, enabling a duct to be attached into the fuselage for cold climate stops or layovers, and ramp and maintenance functions.
