Compressor Commissioning & Installation Services
The definition of Commissioning from Compressed Air Best Practice magazine, “Compressed air system commissioning is the
process for measuring, testing, adjusting, and documenting that the performance of an entire compressed air system achieves the target
system efficiencies (scfm/kW as a whole and for each piece of equipment) in all load regimes and potential failure modes.”
Proper compressor installation and commissioning helps ensure trouble-free startup and long-term reliability. Thorough inspection and
critical review during each phase of the installation process eliminates “built-in” deficiencies or problems which could later result in
equipment failures or poor performance.
Commissioning: Start with the Preparation
Checking your air compressor before the installation is critical to its' success. The checklists in the below sections are intended to aid
in this inspection/review process, but refer to your manufacturer's instruction manual for exact details.
Installation Checks
{"values":"Installation is per manufacturer's instructions "}
{"values":"Belt properly aligned "}
{"values":"Compressor turns freely"}
{"values":"Compressor in place and properly anchored"}
{"values":"Shipping pallets removed"}
{"values":"Power disconnect is located within site of the unit it controls and labeled"}
{"values":"All electric connections tight "}
{"values":"Safeties installed and operational "}
Reverse Rotation Check
This is probably the single most important startup item that should be conducted before starting the compressor.
The compressor should be “bump started” (i.e. control power de-energized immediately after startup) and the direction of the pressure gauge
movement should be checked to insure that the discharge pressure rises upon compressor start. If the compressor rotation is backwards the
discharge pressure will be pulled immediately into a vacuum, on a rotary unit this will starve the air-end of needed oil and cause air-end
damage within a seconds. If the rotation is backwards, the phasing of the compressor should be corrected (reversing any two leads will
change rotation) before attempting to re-start the compressor.
Some 3 phase units come with a piece of paper taped to the top of the cabinet. If the electrical phases are correct when started it will
blow the paper up revealing an OK on the bottom, this indicates the rotation is correct. In cases the phases are out of sequence when
started air will be pulled into the cabinet sucking the paper down, this would indicate incorrect phase sequence and wrong motor rotation
and would need corrected immediately before restarting.
Start-Up Of the Compressor
Great news, your pre-commissioning is all set. Now is time for installation and the next round of commissioning checklists. Below are a few
things to keep in mind during start up.
Startup Check List
{"values":"Pull disconnect and ‘lock out’ switch"}
{"values":"Activate disconnect switch"}
{"values":"Bump for proper rotation of motors"}
{"values":"Close receiver valve and start "}
{"values":"With valve closed let machine come up to pressure "}
{"values":"Check for proper cycling operation"}
{"values":"VFD interlocked to control system "}
{"values":"Open receiver valve"}

Just like any other equipment, a compressed air installation also requires the necessary maintenance work during its entire
lifespan. Even though maintenance costs are only about 5 to 10% of a machine's annual operating costs, failure to budget for
maintenance can have potentially disastrous consequences.

Using nitrogen is not about fully replacing CO2, but it can reduce their consumption of CO2 by close to 70%. Using nitrogen is about
sustainability. Creating your own nitrogen is easy and will reduce the use of a greenhouse gas, which is better for the environment. It will
also save you money as early as month one adding that savings to your bottom line.

Providing a safe working environment for operators is essential, especially when using pneumatic tools and compressed air. If there is a
failure in the air network and the hose is not adequately clamped, the resulting whiplash could be devastating. Failure to follow best
practice can result in injuries, associated production downtime and decreased productivity.

A common questions asked is why do I need an air dryer for my compressor? Typically, air compressors produce water, and although the
water can be drained, there can still be aerosol and vapour droplets that are present. This is because water cannoet be compressed. Water
can damage your compressor by corroding the valves, pipes and machinery controls, which will cost you time and money to resolve. In
the long run, the cost of a new compressor is a small price to pay compared to the loss of production that could potentially arise due
to water damage in your compressor.
Air compressors can fail for an assortment of different reasons: Normal wear and tear, lifespan and age of the unit, poor maintenance, power surge, install issues are just a few the come to mind. Check out this blog to find out our top 7 tips to ensure your compressor is looked
after!

If you're wondering what an air compressor actually is, you've come to the right place. Simply, air compressors convert power in to air that
is pressurised which is then used to power air tools such as spray guns. Air compressors are used in a wide range of applications, so
naturally if you want one that will be designed for spray painting your vehicle, you want a compressor specifically made for spray guns!
This way your compressor will be able to provide the right amount of power to perform the job.
