Air Rotation Units

Up to 170,000 CFM

YORK® Air Rotation Units (ARUs) are high-capacity, ductless HVAC solutions engineered to efficiently heat, cool, and circulate air in large, open spaces—delivering uniform temperature and humidity control with fewer components and lower operating costs.

Each system conditions up to 150,000 sq. ft. while reducing energy demand and heat stratification.
Eliminates ductwork, reduces mechanical complexity, and cuts installation and maintenance costs.
Delivers even temperature and airflow from floor to ceiling in single-zone environments.

Air Rotation Units

Consistent Conditions for Large Areas

YORK® Air Rotation Units (ARUs) are engineered specifically for large, open, single-zone environments such as warehouse, distribution, and manufacturing facilities, sports complexes and conference facilities, and wholesale clubs and big box stores. Unlike conventional rooftop systems, ARUs use vertical, ground-mounted air handlers and high-efficiency air movement to circulate and condition air throughout the entire space.

By continuously rotating air from ceiling to floor, these systems eliminate stratification, improve temperature consistency, and reduce wasted energy. Their ductless design simplifies installation, minimizes infrastructure requirements, and allows flexible indoor or outdoor placement - making ARUs an ideal solution for both new construction and retrofit projects.

Benefits

Uniform temperature and humidity control

Maintain consistent conditions across large spaces.

Reduced energy consumption

Destratification and efficient air movement provides desired conditions using less energy than competing systems.

Lower installation costs

Elimination of ductwork and fewer components simplifies installation and comissioning.

Safer maintenance

Ground-level service access makes service work safer and simpler compared to competing systems.
