DEDICATED OUTDOOR AIR SYSTEM
Ventilation Direct's Dedicated Outdoor Air System (DOAS) is the ideal HVAC solution offering exceptional energy savings and unprecedented comfort and humidity control.
The DOAS is designed from its core to conserve energy and save on operating costs. Its rare earth magnet inverter scroll compressor eliminates excessive cycling, premature unit aging, inefficient hard starts, and unnecessary energy consumption. Modulating technologies allow it to deliver the highest efficiencies at part-load conditions.
The DOAS contains fully modulating refrigeration and optional hot gas reheat components that deliver the exact amount of air requested at the desired temperature and humidity. Variable speed components allow the unit to adjust its heating and cooling capacity to match the required load. This provides a consistent temperature throughout the space and avoids large temperature swings often associated with single stage equipment.
The DOAS achieves an impressive 20.2 IEER rating (Integrated Energy Efficiency Ratio) which is over 1.5x the ASHRAE 90.1-2016 IEER standard. Designed with the future in mind, it is poised to exceed rising IEER standards for years to come.
Ventilation Direct offers unmatched factory service and technical support through its rapidly expanding nationwide service team. Each local service technician undergoes extensive in-house training to ensure your needs are quickly met and problems are thoroughly addressed. Since the DOAS is a fully standardized equipment line, service techs are able to stock most replacement parts on their trucks, eliminating long lead times often associated with service visits. Additionally, Ventilation Direct's DOAS is designed with service in mind, incorporating several convenience features to make support visits as smooth and efficient as possible.
