Bring in fresh air for greater comfort and lower costs

A common form of ventilation, make-up air (MUA) units are designed to bring in fresh, outdoor air to replenish the air that’s been pushed out through exhaust systems. For buildings with greater ventilation requirements, condensing make-up air (MUA) units can improve air quality and comfort while achieving even greater energy savings.

How do condensing MUAs work?

MUA units take in fresh air from outdoors. The air first passes through filters and dampers to regulate how much air is brought in, removing dust, debris, smoke and other contaminants in the process. It’s then heated with a gas-fired heat exchanger before being blown as tempered air into a space.

Condensing MUA units are similar to non-condensing models, but with much more efficient burners and multiple heat exchangers that extract more waste heat. With less natural gas needed to heat the air, condensing MUAs provide the same level of output for a lower cost.
