In large commercial and industrial spaces, winter heating can feel like an uphill battle. Warm air naturally rises to the ceiling, creating a toasty upper layer while workers on the floor shiver in cold pockets. This thermal stratification doesn’t just compromise comfort—it drives energy costs through the roof as systems overwork to compensate. Air Rotation Units (ARUs) from Althoff Industries, Inc. solve the problem by gently recirculating air from top to bottom, delivering even temperatures, lower bills, and a more productive environment.
