Why use Horizon Dedicated Outdoor Air Systems (DOAS)?
Higher indoor air quality	Improve indoor air quality by properly conditioning and filtering the outdoor air required to ventilate a building.
Lower overall HVAC energy use	Efficiently condition outdoor air and reduce the load on local HVAC equipment.
Smaller local HVAC equipment	When Horizon Dedicated Outdoor Air Systems deliver outdoor air that’s either at a cooler temperature or at a lower dew point than room-neutral air, the local cooling equipment — such as fan coils, water-source heat pumps, VRF terminals, etc. — can be smaller.
Effective humidity control	Optimized for efficient humidity control, which improves occupant comfort.
A variety of HVAC solutions	Easily integrated with a wide variety of other HVAC systems — or used in a standalone application, such as a kitchen.
