Understanding the CAGI BL 5389 standard
This standard provides a simplified, wire-to-air performance test applicable to a packaged atmospheric air turbocompressor.
In 2010, CAGI members were approached by the Consortium for Energy Efficiency (CEE) to address the need for test standards for centrifugal and positive displacement blower packages among the CEE membership, which comprises the electricity provider program administrators. A working group within CAGI’s Blower Section formed soon after.
The working group embarked on a standard development project which culminated in the release of the BL 5389 standard in 2013. The standard is intended to eventually become an annex to the ISO 5389 standard, which provides an extremely detailed, complex procedure to test and rate turbocompressor blowers. The new, BL 5389 standard provides an easily integrated, cost effective, yet highly accurate "wire to air" approach to testing. It is applicable to all dynamic blower packages in all industrial and municipal air applications. While the standard is intended for use with all types of turbocompressor blower packages, it will be particularly useful for machines that are manufactured in batches or in continuous production quantities.
