Have you got a Frankenstein blower package lurking in your system? Without a doubt, it comes alive when you flip the switch, but do you really know how efficient the package is? If you’ve got a monster of an electricity bill, you are not alone. Here’s how package integration can help keep that inefficiency monster at bay.
It’s really a matter of piecemeal engineering vs. package integration. Historically, blower packages were assembled using components separately sourced from a number of different vendors and then assembled onsite. The number one basic concern was component requirements—not on how the individual pieces worked together. The result was highly customized, individual, “Frankenstein” blower packages that were not assembled and tested together, making it nearly impossible to know how efficient the blower package actually was.
Dr. Frankenstein’s method may produce a functioning package, but it doesn’t take into account the power losses and flow restrictions from the blower blocks, silencers, filters, valves, pumps, fans, and drives. And those losses add up.
Consider instead, package integration where a single supplier builds the entire blower unit. Not only do you save significant time, money, and energy on specifying individual components as well as on installation, you also have a complete package where each and every part has been selected to work together in the most efficient way possible.
Package integration has also made performance testing possible and the Compressed Air and Gas Institute (CAGI) has developed performance data sheets for blowers to more easily compare performance between different manufacturers.
So do yourself a favor. Save some headaches and back and forth with Igor on which parts to specify and go with an integrated blower package.
