A facility utilizes 12 belt driven fans. Each of these motors is rated at 25 hp and have an efficiency of 88.6%. These fans run with a 100% load factor, and a duty factor of 80%. The plant operates 9 hours a day, 365 days per year.
Currently the facility uses standard V-belts, but is considering upgrading to cogged V-belts. What would be the anticipated energy savings (in kWh) for making this change?
