Allmand Bros. Inc. has upgraded its Maxi-Heat portable heater with higher static pressure.
Incorporating a new fan-motor combination and increasing the static pressure from 0.5 wg to 1.5 wg, the upgraded Maxi-Heat is able to accommodate up to 110 feet of 16-inch ducting, as opposed to 40 feet with the previous model.
The Maxi-Heat features twin heater units that produce a maximum of 1,010,000 btu and may be operated independently, depending on heating requirements. A standard 1,800-rpm liquid-cooled Isuzu diesel engine with regulated generator provides power for the heaters and electrical accessories. A 191-gallon fuel tank provides more than 24 hours of operation without refueling.
In addition to the static pressure and ducting upgrades, Allmand has added an in-line fuel heater and prefilter to the Maxi-Heat’s fuel system to improve heater performance and durability.
