TEAM UP!FOR FAN AND PUMP SAVINGS

It can be as easy as replacing an old drive

belt.

For the environment

Replacing a worn-out drive belt can drive big environmental gains.

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.

What can we do?

1. Housekeeping2. Low-cost

opportunities3. Retrofits

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.

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.

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.

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.

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Replace outdated units with more efficient and correctly sized equipment.

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.

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.

Thank you

Together we can make it happen.

It’s good for the environment.

It’s good for the bottom line.
