Many industries now require air to be ducted up to 100 feet. The Maxi-Heat features twin heater units that produce a maximum of more than 1 million BTU and may be operated independently. A standard 1,800-rpm liquid-cooled Isuzu diesel engine with a regulated generator provides power for the heaters and electrical accessories. A 191-gallon fuel tank allows for more than 24 hours of operation without refueling. To improve heater performance and durability, Allmand has also added an in-line fuel heater and pre-filter to the Maxi-Heat’s fuel system.
