The most powerful and durable GSE heaters today are the Spencer Coldbuster Mark IVs. The Mark 4-900 delivers clean and filtered hot air at 165-180 degrees above ambient in sub-zero climates. Capable of delivering 900,000 BTUs at up to 6,000 cfm, this heater cart can handle any commercial aircraft in service today.
The Mark 4-900 uses the “turbo-dynamic” heat exchanger technology, maximizing exhaust heat. Our “VariFlo” control can fully regulate hot airflow for all-size aircraft. New for 2014 is the 50% increase in duct storage space by moving the rear wheels outside of the frame, also giving our unit additional stability.
