  Compressed Air Initiative

Many facilities operate compressed air systems that do not adequately meet the needs of today's critical production requirements. By optimizing your compressed air system, these typical problems can be eliminated.

Is this offer for you?

The Compressed Air Initiative focuses on optimizing large compressed air systems and may benefit your organization if you are experiencing:

  • Frequent pressure drops
  • Shortage of air
  • High maintenance costs
  • High moisture levels
  • Oil carryover

If you are an industrial customer that spends more than $50,000 annually on electricity and has a compressed air system greater than 200 hp, you are eligible to participate.

How it works

The Compressed Air Initiative focuses on improving the design, operation and maintenance issues of the entire system.

Identify Investigate Implement
Compressed Air Savings Estimator (CASE)

BC Hydro provides full funding for the CASE

Energy Efficiency Feasibility Study

BC Hydro provides 75% funding

Project Incentive Funds

Financial incentives of up to 75% of the project cost are available.

 

A BC Hydro energy management engineer identifies opportunities by conducting a Compressed Air Saving Estimator (CASE) of your system. Based on the opportunities identified in the CASE, the next step would be a comprehensive investigation of your compressed air systems through an Energy Efficiency Feasibility Study

After that, they will help you get your project off the ground by offering you financial incentives of up to 75% of the project cost. Key account managers, engineers and pre-qualified consultants will work together to guide you through every stage of the process, from identifying and investigating efficiency opportunities to implementing successful projects.

Sustaining the savings
Compressed air data is monitored and periodic performance assessments are conducted.

Education and training
Comprehensive Compressed Air System Management workshops, which are run by world-class compressed air experts, are offered for you and your staff to learn the best practices for managing your compressed air systems. 

It pays to take action

A high-performing system can provide more available air at consistent air pressure, better air quality, lower maintenance costs and considerable energy savings.

  • Higher productivity
  • Better system performance and reliability
  • Reduced maintenance and energy costs

 

Compressed Air System Tips

Operating compressed air systems can be expensive. By managing them more efficiently or taking a few proactive steps, you can lower your energy costs and save. Here are some simple steps to help you save on your compressed air systems.

Inspect and repair systems
Leaks are a significant source of wasted energy in a compressed air system, often wasting as much as 20 to 30% of the compressor's output. Compressed air leaks can also contribute to problems with system operations. Fluctuating system pressures cause air tools and other air-operated equipment to function less efficiently, possibly affecting production.

Repairing leaks can save up to 50% of your compressed air annual energy costs.

Continuously monitor compressed air system
On a continual basis, monitor, check and inspect all components of your compressed air systems for wear, proper temperatures and settings, leaks, proper lubrication and clogged filters.

Use compressed air systems at necessary times only
Use compressed air only when and where it is necessary. Shut down your central compressor during non-working hours. If small amounts of compressed air are required, separate those uses from the main system and supply them from a smaller compressor, such as fire sprinkler systems.

Replace drain valves
Consider replacing your old drain valves with new electronic sensing drains which discharge only when necessary. This can save you five times the purchase price in wasted air each year. Older mechanical float type drain valves often get stuck open and timer-based drains open when not needed.

Set pressures according to required processes
Maintain air pressure at the lowest pressure acceptable. Evaluate your pressure requirements carefully. Some facilities operate at higher working pressures to satisfy small high-pressure applications or to compensate for pressure drops from undersized piping.

Upgrade your compressor filters
Replace old compressor filters with new energy-efficient filters with lower pressure drops.

Maintain air receivers
Maintain the air receiver in good condition and ensure it is drained effectively at regular intervals. A timer and solenoid valve can help. Install compressor air intakes where they will receive the coolest air available.

Examine purge cycle on dryers
Examine the purge cycle on dryers. Often, dryers are purged for longer than is required to dry out material.
