It can be as easy as

patching a hose.

TEAM UP!

FOR COMPRESSED AIR SAVINGS

For the environment

For the bottom line

Why should we care?

Why should we care?

For the environment:

Patching a hose can put the seal on big environmental gains.

For our bottom line:

Patching a hose can pump up savings

Why should we care?

For our bottom line:

Typically, for every 100 units of energy, fewer than 10 units become useful compressed air.

A 1 cm hole in a hose can

cost about $11,000 a year in wasted energy.

Why should we care?

1.Housekeeping

2.Low-cost opportunities

3.Retrofits

What can we do?

1. Housekeeping

Inspect and maintain the air system and control and monitoring equipment.

Always shut off compressed air when not needed.

Never use compressed air for dusting and cooling.

Prevent leaks by checking joints, valves, fittings and hose connections.

What can we do?

1. Housekeeping (cont’d)

Generate compressed air at the lowest possible pressure for each job.

Check that the system isn’t requiring higher pressure than it was designed for. Does it need recalibrating?

Maintain clean air filters to optimize system efficiency.

What can we do?

2. Low-cost opportunities

Meter usage by end-point users.

Institute a usage cost breakdown per user.

Ask users to justify use.

What can we do?

2. Low-cost opportunities (cont’d)

Eliminate hoses and couplings to reduce leaks.

Use the coolest possible intake air, and look at ways to use outside air.

Discharge air-cooled compressors outside in summer and inside in winter.

What can we do?

2. Low-cost opportunities (cont’d)

Make sure the system is dry, to prevent leaks from corrosion and winter freeze ups.

Shut down the screw compressor and use the reciprocating compressor for partial loads.

What can we do?

3. Investigate retrofits

Integrate independent compressed air generating and distributing circuits

Use an intelligent control system to reduce idle time and maintain correct pressure

Use a combustion-engine-driven compressor for heat recovery and better part-load efficiency than electrical motors.

What can we do?

3. Investigate retrofits (cont’d)

Upgrade to an energy efficient compressed air dryer

Install a larger buffer tank to improve compressor loading on older compressors.

Use a centralized automatic leak-

measuring system.

Replace old steel pipes with plastic pipes to avoid corrosion and leaking.

What can we do?

We have the people

We have the tools

How can we do it?

Thank you

Together we can make it happen.

It’s good for the environment.

It’s good for our bottom line.
