The Herman Nelson (BT-400 NEX Series) heater consists of a forced air furnace that can burn gasoline or any type of oil, including diesel and all types of jet fuel.
A gasoline or diesel engine drives a fan which moves air over a heat exchanger. This produces clean, breathable, extremely hot air. This air can be directed via ducts to be concentrated on the work area.
Both the engine and furnace draw fuel from an integrated tank. BT-400 NEX Series heaters are either mounted on rugged trailers for ground transport (Diesel Heaters) or free standing to be loaded in the back of a ½ ton, transported in fixed wing aircraft or helicopter to the work site (Gas Heater – Trailer Available).
BT-400 NEX Series heaters produce a temperature rise of “up to” 290 degrees with an air movement rate of 2,100 CFM. The heaters are certified to operate at temperatures down to -40 degrees F or C.
BT-400 NEX Series heaters produce in excess of 400,000 BTU's
During 2010 the "original" Herman Nelson just got better with all electronic controls and valves and CSA,
UL and OTL certification to operate in extreme outdoor locations and/or indoor.
In addition to the #1 selling "extreme / original" Herman Nelson, Aerotech has a full line of portable Flame
Less Heaters that produce heat by compressing hydraulic fluids to create up to 1.2 million BTU's and
7,200 CFM. This technology is now the standard where the risk of spark / open flame is out of the question. Fuel depots, munition factories, gas/oil exploration or highly secured areas such as air fields and military bases. Flame Less Heat by Aerotech Herman Nelson!
