Packaged DX For A School

This unit was built with a complete, on-board, packaged 410A refrigeration circuit including compressors, condensing section, DX coil, and Hot Gas Reheat. For winter heating, it also has an indirect gas-fired furnace. The components, plumbing, wiring, and controls for all these systems were installed at the factory. The unit was built for a school in Connecticut to provide year-round total air conditioning, and with the combination of energy recovery, 410A high pressure refrigerant, and airfoil blowers it is one of the most energy efficient units available.
