BT400-NEX-NSN

Add to Quote

The BT400 NEX-D is a Kubota diesel engine driven stand-alone indirect fired heater producing 400,000 BTU/H.

Featuring a high efficiency stainless steel heat exchanger which exhausts all combustion gases up the exhaust stack.

This allows the BT400 NEX-D to provide 100% breathable air which can be blown into an aircraft cabin or engine, a worksite or building.

The heater is designed to operate in extremely cold temperatures – below -40 °F/C and. The BT400 NEX-D is also certified for indoor use, operating free-standing inside a building provided that the exhaust fumes are plumbed up a stack to the outside of the building. This creates a 400,000 BTU portable furnace while the electronic temperature controls the temperature.

Temperature range 150 °F – 250 °F
