Engineered Air

The HE series make up air units offer the most efficient available method 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 part of combustion. With heating capacities up to 14,000 MBH and air capacities up to 100,000 CFM.

They are also available in variable capacity, dual capacity, air curtain, and/or heat recovery configurations.
