  1. TEAM UP!FOR FAN AND PUMP SAVINGS It can be as easy as replacing an old drive belt.

  2. Why should we care? • For the environment • For the bottom line

  3. For the environment Replacing a worn-out drive belt can drive big environmental gains. Why should we care?

  4. Why should we care? For the bottom line Installing variable speed drives can result in energy savings of 40 to 60 percent.

  5. Fans and Pumps • Fans provide the motive force to move air against the resistance of an air-conveying system. • Pumps provide the motive force to move liquids against the resistance of a piping system and against changes in elevation. • Both use electric motors and drives.

  6. What can we do? • Housekeeping • Low-cost opportunities 3. Retrofits

  7. What can we do? • 1. Housekeeping • Inspect and maintain fans and pumps. • Check and adjust belt drives regularly. • Correct excess fan noise and vibration. • Clean and lubricate fan components. • Clean or replace air filters regularly. • Clean ductwork, and fix duct and component leaks.

  8. What can we do? • 1. Housekeeping(cont.) • Clean pump impellers, and repair or replace if eroded or pitted. • Maintain clearance tolerances at pump impellers and seals. • Shut down fans and pumps when not needed.

  9. What can we do? • 2. Low-cost opportunities • Streamline air-duct connections to reduce losses. • Optimize airflow, by balancing dampers in their maximum open positions for balanced air distribution.

  10. What can we do? • 2. Low-cost opportunities(cont.) • Replace packing-gland pump seals with mechanical seals, which require far less pump power. • Trim the pump impeller to match system flow rate and head requirements.

  11. What can we do? • 3. Retrofits • Add variable speed motors and drives so the flow of air or water can be adjusted to changing requirements. • Replace outdated units with more efficient and correctly sized equipment.

  12. What can we do? • 3. Retrofits(cont.) • Decentralize a major system into sub-systems that serve their own specific requirements. • Control the ventilation system with ultrasonic occupancy sensors – this saved one manufacturer 50 percent in fan operating costs.

  13. What can we do? • 3. Retrofits(cont.) • Install a computerized energy management control system. • Install variable voltage, variable frequency inverters to allow motor speed to be continuously varied to meet load demand – power savings range from 30 to 60 percent.

  14. How can we do it? • We have the people. • We have the tools. • oee.nrcan.gc.ca/industrial

  15. Thank you • Together we can make it happen. • It’s good for the environment. • It’s good for the bottom line.
