Overview
- The ExhaustFlow Technologies system utilizes building exhaust air to enhance HVAC equipment efficiency.
- Heating operation typically provides the greatest efficiency gains due to the significant temperature difference between the exhaust air and ambient conditions.
- This reduces reliance on supplemental heating sources such as gas or electric backup heat, further improving overall system efficiency.
- Compatible with all major HVAC manufacturers. Ideal for chillers, heat pumps, and packaged DX equipment.
