DOAS: Johnson Controls
Johnson Controls has released a new Dedicated Outdoor Air System (DOAS) that meets ASHRAE 62.1 fresh air requirements. The company says the DOAS delivers up to 100% clean, dehumidified outside air in all weather and climate conditions.
The York DOAS is fully configurable and includes foam panel double-wall construction, R13 insulation value, renewable/organic insulation material, safe-bottom lifting, pre-painted G90 galvanized steel, and hinged and lockable doors.
A direct drive plenum fan is at the heart of the York DOAS, and an energy recovery module pre-conditions fresh air by using energy from the exhaust air. The system also features stainless steel heat exchangers, MERV 8 and MERV 13 filters, independent modulating reheat circuit, VFD supply fan control, and ECM condenser fans.
