Dedicated Outdoor air System (DOAS) WSHP

Dedicated outside air systems (DOAS) bring the outside in by drawing 100% outside air through the unit and into the building’s HVAC system to improve indoor air quality and ensure that proper ventilation is efficiently delivered to the desired space.

The Smart Source DOAS water source heat pump is designed to accommodate a diverse range of entering air conditions ranging from the hottest summer days to the coldest winter nights. It provides advanced unit control features for maximum application flexibility, incorporates an impressive array of leading technologies to provide premium performance, achieving up to a 7.1 ISMRE rating that is 66% higher than ASHRAE’s 90.1-2019 minimum efficiency, and is offered at a very attractive price.
