Northern Industrial Co. is an engineering company specializing in industrial Make-Up Air Units for efficient ventilation and heating of large industrial facilities.

Makeup air is vitally important to the health and welfare of a building and its occupants. If the proper amount of makeup air is not introduced into a space, consequences can range from exterior doors that are hard to open or close, to buildups of carbon monoxide in the space, to fume hoods that don’t actually control the contaminants they were intended to control. In addition, the outside air that is brought into a building to “make up” the amount of air that has been exhausted has a very significant impact on cooling and heating capacities.

Northern Industrial Co. is an engineering designer and developer of industrial gas-fired air makeup units for industrial building ventilation.

Gas-Fired Pressurization Units move large quantities of air at low temperature differentials (usually 50° or less), which is a strategy to minimize temperature stratification in the large spaces they are employed to heat. The equipment is typically mounted on the roof of the facility or at grade on elevated supports to ensure that the supply air is delivered high. The high air delivery allows for a longer “throw” of the air, thereby requiring less equipment to cover the required floor area. The most common fuel is natural gas, however, units can be converted to burn propane. There are two primary categories of gas-fired AHUs: indirect-fired and direct-fired.
