Challenge

What are outdated HVAC belt drives costing you? HVAC systems play a critical role in keeping us comfortable whether in an office, commercial, or residential building. The people who keep them running, including building managers and engineers, constantly monitor performance, costs and repair schedules to ensure comfort and long operational life.

Have you considered that using existing technology may not be maximizing your repair costs and actually may be wasting energy costs? Consider that 50% of all energy used in buildings is tied to HVAC/R.

HVAC Statistics

• Belt drives are the means of mechanical power transmission for over 80% of commercial HVAC equipment.
• Typical method of replacement for worn components is to replace like-for-like
• Half of all commercial buildings were constructed before 1980
• Commercial building energy usage = 11.0% cooling, 11.5% ventilation, 3.7% space heating. = 26.2% for all HVAC equipment
• Wrapped and notched are the two typical types of belts used on belt-driven equipment
• Wrapped belts have a peak power transmission capability of 95%-96% efficiency
• Notched belts transmission capability are 98% efficiency
• The current installed base of notched vs. wrapped is approximately 57% - 60% wrapped
