BENEFITS & FEATURES
-
Improved occupant comfort and building health
Indoor air that’s too humid can result in occupant discomfort, mold and microbial growth, and even a shorter HVAC equipment life. A Horizon dedicated outdoor air system handles dehumidification independently from the rest of the HVAC system, ensuring the optimal level of moisture in your indoor environment.
-
Higher energy efficiency
Both Horizon DOAS and Horizon Flex deliver dehumidification with a high level of energy efficiency. Horizon DOAS exceeds the minimum requirement from ASHRAE® 90.1, as rated by AHRI 920; while Horizon Flex is designed and certified to AHRI 340/360 and meets the minimum EER and IEER efficiency standards.

A Family of Solutions
Horizon® Dedicated Outdoor Air Systems
For buildings with the highest performance requirements, Trane’s Horizon Dedicated Outdoor Air System (DOAS) helps improve indoor air quality (IAQ) to keep your building optimized and your people comfortable. It eliminates excess moisture, preventing discomfort and the health risks associated with mold and microbial growth. Horizon DOAS is designed specifically to condition 100% outside air year-round, reduce latent loads, enhance the entire building system's comfort and energy efficiency, and maintain your building's health.
Horizon® Flex
Application-Specific Outdoor Air Systems
Not every building requires 100% outdoor air or a very low dewpoint, so why invest in more equipment than you need? While our Horizon Flex unit can deliver 100% outdoor air, many customers find that their application requires more than what is delivered in a standard unit but less than a 100% outdoor air, making the Horizon Flex the ideal choice for lower upfront costs.
