Upgraded Maxi-Heat portable heater useful in many industries

Allmand Bros. Inc. has upgraded its popular Maxi-Heat portable heater with greater total fuel capacity, which is in addition to earlier upgrades that include higher static pressure and the ability to run longer ducting.

 The Allmand Maxi-Heat MH-1000 heater trailers now feature three smaller molded poly fuel tanks instead of a single large steel tank. The new fuel tank system has one 50 US-gallon engine supply tank, and two 100 US-gallon heater supply tanks. The nearly 60 gallon increase will provide more than 30 hours of continuous operation without refueling.

As an added benefit, the new molded polymer tanks are corrosion-resistant. In addition, the lighter material reduces the overall weight of the tanks, partially offsetting the additional weight resulting from the increased fuel capacity.

Reduced capacity of individual tanks means that no single tank is over 450 Liters (118 US gallons). This brings the trailer under the fuel capacity limits of Transport Canada regulation CGSB 43.146, meaning that no initial or subsequent tank certifications are required, resulting in a substantial cost savings over the life of Maxi-Heat trailers falling under Transport Canada regulations.

The static pressure of the Maxi-Heat was increased from .5” wc to 2.3” wc. This increase in static pressure has allowed Allmand to increase the length of the Maxi-Heat’s 16-inch ducting from 40 feet to 110 feet.

The Maxi-Heat plays an important role in the mining and petroleum industries, cement curing, equipment pre-heating, pipeline construction, restoration and general construction. According to Allmand Director of Marketing, Doug Dahlgren, the new upgrades to Maxi-Heat have increased both the performance and versatility of the portable heating unit.

“There are many applications that now require air to be ducted up to 100 feet,” Dahlgren said. “Incorporating a new fan-motor combination and increasing the static pressure helps ensure that clean, breathable air can be delivered to the work area, and provides a wider variety of heat distribution options.”

Maxi-Heat features twin heater units that produce a maximum of 1,010,000 BTUs and may be operated independently depending on heating requirements. A standard 1,800-rpm liquid-cooled Isuzu 3CD or optional CAT C1.5 diesel engine with regulated generator provides power for the heaters and electrical accessories.

In addition to the fuel tanks, a static pressure and ducting upgrade, Dahlgren says Allmand has incorporated another important performance feature into the Maxi-Heat. “We have also added in-line fuel heaters and pre-filters to the fuel system on the unit,” Dahlgren explained. “This is especially important in those situations where fuel may be contaminated or may not be blended properly for the operating conditions. The heater/pre-filters makes the system more tolerant to dirt and variances in the viscosity of the fuel, which means improved performance and dependability.”
