A Turbo Blower for the Base Load, PD Blower for the Peak Load
A biological municipal wastewater treatment plant with a considerably fluctuating discharge quantity can only perform its function with utmost energy efficiency and reliability if the process air consumption of the aeration basin can be adjusted continuously and is fully automated in order to deal with widely fluctuating load quantities. The example of the wastewater treatment plant shows how this is achieved with the use of a speed controlled Aerzen turbo blower.

Shipping damage is the top number one issue followed by scheduling and only then cost. It is amazing how much freight gets damaged per year. This is particularly true for new blower packages that are shipped via LTL (Less than truckload) and so called common carrier. Although deemed the most cost effective – expediting and broker companies managed to push the cost down - it is the most difficult way to get machinery to a job site undamaged. Because freight must be consolidated in the carrier’s main hubs the equipment must be moved often. The mostly heavy and odd shaped freight with uneven weight distribution is moved with fork trucks that are significantly undersized. Making things worse is the fact that logistics is a business model where people make Cents on a Dollar and thus the time freight spends in non value adding moving around within terminals is kept to an absolute minimum causing fork lift drivers to drive fast and furious. Freight gets shoved around, stacked (when it should not be) and dropped rapidly (giving drop-shipment a different meaning). The result is that sound enclosures, castings, instrumentation etc gets damaged significantly before it even makes it to the final destination.

Operating Time Versus Condition Based Oil Changes
The majority of all operating manuals provide the equipment user with a time based plan when to change the machine’s oil. This interval is typically designed to protect the oil and subsequently the machine from breaking down prematurely in most if not all operating conditions. So far so good. This comes with a price tag as the machine needs to be properly shut down and locked / tagged out. Besides of the obvious cost for the lubricant you also incur labor and potential production down time cost. For most of the smaller machines requiring less than a gallon of oil for each change it may not make sense to go with a condition based lubricant change. Experts fix what needs fixing and this applies here also. For larger quantities it may make much more sense to go with an oil condition based oil change schedule.

PD Blower "Free" Oil Analysis - There Is Usually A Good Reason For It
Oil analysis and vibration analysis make a great tag team when it comes to assessing rotating equipment condition. Even if oil analysis trending is carried out by itself it still can be a powerful tools assessing whether or not there may be trouble coming down the pike – rolling element bearings, gears and other key components leave key evidence of them failing behind in the lubricant. Depending on your plant size and usage of lubricant, quite a few lubricant suppliers also offer free oil analysis. While that seems great at the first glance, there are quite a few wrinkles that can lead straight to catastrophes that the analysis was supposed to help prevent. I will review a few issues and elaborate on what an analysis report should cover in the course of this blog.

Considerations when specifying and purchasing a screw compressor
1) Type of compressor: positive displacement or dynamic

Things to consider when making blower purchasing decisions
Performance - Only buy Aerzen's blower packages... just kidding, but there is a serious point here. Any manufacturer's claims of performance need to be verified to insure the correct amount of pressure will be generated for the application. Insist on knowing the performance and efficiencies (power requirements) of the complete blower package you buy not just the performance of the bare stage. An undersized drive motor will limit performance.
