Our Products

The HE Series make-up air units offer the most efficient method available to heat make-up air. Direct fired make-up air heaters may be considered to be 100% efficient because no heat is vented to the atmosphere.

The theoretical 100% efficiency should be reduced to 92% due to water vapor being formed as a natural by-product of the combustion process. Units are available with heating capacities up to 14,000 MBH and air capacities up to 100,000 CFM. Units are also available in variable capacity, dual capacity, air curtain, and / or heat recovery configurations.

The RE Series mix air units offer the most efficient method available to heat mix air. Direct fired make up air heaters may be considered to be 100% efficient because no heat is vented to the atmosphere.

The theoretical 100% efficiency should be reduced to 92% due to water vapor being formed as a natural by-product of the combustion process. Units are available with heating capacities up to 11,000 MBH and air capacities up to 100,000 CFM. Units are also available in variable capacity, dual capacity, air curtain, and/or heat recovery configurations.
