Incorporating a new fan-motor combination and increased static pressure, the upgraded Maxi-Heat portable heater from Allmand Bros. is able to accommodate up to 110 feet of 16-inch ducting, compared to the 40 feet maximum of the previous model. 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.
