Constant Volume System

The constant volume 100% direct-fired make-up air system heaters provide a constant rate of supply air to the space. The gas flame in the unit heats the fresh make-up air directly, eliminating energy losses associated with other types of heating. For most applications, introducing slightly more make-up air into the space than what is exhausted produces the best results. A slightly positive building pressure assures the best performance. Some applications, such as themore
