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