Project Overview:

Dover Air Force Base in Delaware needed new equipment to replace old and failing unit heaters in a hangar that stores the jet engines for the Air Force’s C5 Galaxy planes. Each engine is valued at approximately $1 million dollars, and there are about 40 of them housed in the hangar.

The Air Force Base chose two AbsolutAire I-Series to heat the space and keep the engines and sprinkler systems from freezing. The units are designed to maintain constant discharge temperature to protect both the building and its contents. Building pressure controls maintain a slight pressure in the space, minimizing infiltration of cold air, dust, and dirt from the outside, even as hangar doors open and close throughout the day. VFD-controlled fan speed allows for maximum energy conservation while operating at low speed and maximum air tempering during high-speed operation.
