Dedicated outside air systems
York's dedicated outside air systems allow easy adapt to all climate conditions, demanding applications and evolving industry standards.
York’s line of dedicated outside air systems (DOAS) includes a range of 100% outside air units and mixed air units that provide users with more options and greater application flexibility. With heat pump operation and water source operation, as well as a hot water heat option, the line of air systems delivers combinations of heating and cooling. The systems also feature an internal energy recovery wheel that pre-conditions outside air and reduces heating and cooling loads by transferring energy between the exhaust airstreams. The DOAS line offers air or water cooled units, in various configurations ranging from cooling only to heat pump. A full selection of factory-installed options adds to system flexibility.
