Allmand Bros. now offers its upgraded Maxi-Heat portable heater with greater total fuel capacity. 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-gallon engine supply tank and two 100-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, and the lighter-weight material reduced the overall weight of the tanks, partially offsetting the additional weight that results from the increased fuel capacity. Now no single tank is greater than 450 litres (118 gallons), which 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 — a substantial cost savings over the life of Maxi-Heat trailers.

This new increased fuel capacity is in addition to earlier upgrades that include higher static pressure and the ability to run longer ducting. The static pressure of the Maxi-Heat increased from .5- to 2.3-inch water column, which allowed the company to increase the length of the Maxi-Heat’s 16-inch ducting from 40 to 110 feet.

“There are many applications that now require air to be ducted up to 100 feet,” says Doug Dahlgren, director of marketing, Allmand Bros. “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 provided a wider variety of heat distribution options.”

The self-contained, versatile, high-output Maxi-Heat MH-1000 heater trailers are well suited to the rental market because of their compact size, low profile and indirect-fired feature.

“We have also added in-line fuel heaters and pre-filters to the fuel system on the unit,” says Dahlgren. “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.”
