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.
Trane® / Mitsubishi Electric VRF products include a variety of outdoor units, indoor units, ventilation solutions, controls, and more to design a complete VRF system for any building.
