Belt Drive Retrofit Solution

Challenge

 

What are outdated HVAC belt drives costing you?  HVAC systems play a critical role in keeping us comfortable whether in a commercial, office or large residential buildings. 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.

But 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
  • Of belt driven equipment there are 2 typical types of belts, wrapped and notched
  • Wrapped belts peak power transmission capability are 95%-96% efficiency
  • Notched belts transmission capability are 98% efficiency
  • The current installed base of notched vs. wrapped is approximately 57% - 60% wrapped
  • HVAC/R uses 50% of all energy in U.S. commercial buildings
  • Research suggests that about 50% of the fans in use will not comply with the new federal regulations and will need to be upgraded or replaced

Lifecycle Services


A prominent healthcare facility in Los Angeles, California had an aging fleet of HVAC systems in their facility. The equipment had worn sheaves, worn belts and under-tensioned belts which indicated the HVAC systems were operating well below expected efficiency levels. The facility owners were interested in the Browning® “Save the Green/Sustain the Green” program and were considering a mass retrofit of all belt drives. However, they required proof of energy savings to justify the cost of the retrofit project. Read more…

 

Browning Belt Drive Upgrade Program – Energy Responsibility in 4 steps 

  1. Upgrade from wrapped to notched belts and improve efficiency. Wrapped v-belts can run up to 95% efficient, whereas notched v-belts can run up to 98% efficient!
  2. Replace Worn Sheaves
    • Groove wear greater than 1/32” indicates replacement is needed
    • Belt should never ride in bottom of groove
    • Inspect for breaks on flange
  3. Properly Tension Belts. Example of glazed belt due to under tensioning and worn sheaves.
  4. Install self-adjusting motor base. Tenso-Set® Series 600 horizontal sliding motor base (with optional quick release) enhances technician convenience and belt drive efficiency by automatically maintaining belt tension for extended periods and allowing quick belt changes.
