Fresh Air Ventilation for the New Education Wing

Not every job requires an enormous amount of equipment. This unit and two others like it were used to ventilate a high school addition in eastern Pennsylvania. The low-profile, horizontal configuration works well for roof-top applications, reducing un-slightly equipment profiles while providing clean and easy duct connections through the bottom of the unit. The hot water coil, also plumbed through the curb, provides additional make-up heat during the coldest winter periods. The Heat-X-Changer makes outdoor air ventilation possible without breaking the school's facilities and operating budget.
