Allmand Bros. Inc.
Allmand Bros. Inc. has upgraded its Maxi-Heat portable heater with higher static pressure and longer ducting. Incorporating a new fan-motor combination and increasing the static pressure from .5 wg to 1.5 wg, the upgraded Maxi-Heat is able to accommodate up to 110 feet of 16-inch ducting, rather than 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 191-gallon fuel tank provides more than 24 hours of operation without refueling.
