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
Why should we care?

• For the environment
• Replacing a worn-out drive belt can drive big
  environmental gains.

4
Why should we care?

• For the bottom line
• Installing variable speed drives can result in
  energy savings of 40 to 60 percent.

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• Replace outdated units with more efficient and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.

How can we do it?

• We have the people.
• We have the tools.
