Unheated Make-Up Air Unit
An unheated make-up air unit is a MUA unit that introduces outside air into a space to replace air that has been exhausted or removed by ventilation or exhaust systems. Unlike a heated make-up air unit, an unheated make-up air unit does not provide any heating to the incoming air.
Make-up air units are commonly used in commercial and industrial applications to ensure that the air inside the building is fresh and meet IAQ standards.
They are especially important in buildings where there is a lot of exhaust or where the air is frequently being replaced, as in laboratories or manufacturing facilities.

Unheated Make-up Air Applications
Unheated make-up air units can be stand-alone units that are installed separately from the building’s heating and ventilation system, or they can be integrated into the system.
In some cases, an unheated make-up air unit may be used in conjunction with a separate heating system to provide both fresh air and heating to a building or space.
In this case, the make-up air unit would be responsible for bringing in the outside air, and the separate heating system would be responsible for heating the air to the desired temperature.
