Greenheck Dedicated Outdoor Air Systems:Among the First in the Industry Certified Under AHRI Standard 920
As building codes evolve and energy performance expectations rise, ventilation systems must do more than deliver outside air—they must do it efficiently, reliably, and with verified performance. That’s where Greenheck Dedicated Outdoor Air Systems (DOAS) stand apart.
Greenheck’s DOAS solutions are designed to supply cooled and dehumidified outdoor air during summer months and heated outdoor air in winter, ensuring consistent indoor air quality while supporting overall HVAC system efficiency. Their comprehensive lineup addresses a wide range of heating, cooling, dehumidification, and ventilation requirements, making them an ideal choice for both DOAS and variable air volume (VAV) applications.
Designed for 100% Outdoor Air Performance
Greenheck DOAS rooftop units are engineered to deliver up to 100% outdoor air, helping buildings meet ventilation demands without overburdening the primary HVAC system. Each unit is pre-engineered and factory-tested, reducing installation risk and ensuring dependable, repeatable performance in the field.
To further enhance energy efficiency, these systems can be specified with a total enthalpy wheel or total enthalpy core, allowing facilities to recover energy from exhaust air while maintaining precise control of temperature and humidity. The result: lower energy consumption, optimized system sizing, and long-term operational savings.
Industry Leadership: AHRI Standard 920 Certification
What truly sets Greenheck apart is verified performance.
Greenheck Dedicated Outdoor Air Systems (DOAS) models RV, RVE, and RVC are among the first in the industry to achieve certification under AHRI Standard 920. This certification confirms that the equipment has been rigorously tested and validated by a third-party laboratory under contract with the Air-Conditioning, Heating, and Refrigeration Institute (AHRI).
The AHRI Certified® mark is the trusted benchmark for performance assurance across heating, air conditioning, and refrigeration equipment. Certification under Standard 920 provides engineers, owners, and specifiers with confidence that published performance data is accurate, comparable, and independently verified—removing uncertainty during design and equipment selection.
At Greenheck, performance isn’t just promised—it’s proven.
