About Aerotech Herman Nelson
Aerotech Herman Nelson, at 100 Eagle Drive in Winnipeg, Manitoba, began in 1973 refurbishing military-surplus ground support equipment and now builds the BT-400 series of portable aircraft and engine heaters that are the standard on turbine and business-jet ramps. Named customers include Delta, WestJet, Air Canada, Boeing, the Canadian Armed Forces and the US military, plus oil-and-gas and construction users.
The BT-400 NEX-D (diesel) delivers 400,000 BTU/h and 1,500 CFM for 14 hours on a tank in a 71×50×48-inch package; the NEX-G (gasoline) matches the output in a smaller 52×21×27-inch frame with an 8-hour run time, and a NSN-coded version and the 588,000-BTU HPL 600D7 complete the line. Sales are direct (1-800-486-4328, request-a-quote; a 3.5% price increase took effect January 1, 2026), and AERO Specialties resells the NEX-D in the US.
