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.

Real-time Condition Monitoring For Blowers And Compressors
The Aerzen iAir Remote Monitoring System (RMS) is a comprehensive monitor that can be attached to any blower or compressor to capture real-time activities and conditions. Based on industrial cellular technology, the RMS can function in any location with cellphone coverage for both indoor and outdoor applications. The system is easily installed and linked directly to your cell phone for up-to-the-minute condition reports and notifications. This allows for peace of mind and troubleshooting when you are not accessible to the equipment.

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.

Top 5 Questions To Ask When Sizing A Blower System With A Vacuum Pump
In order to properly size a blower system with a vacuum pump, there are five main requirements to consider:

Lowering start-up power draw with across the line start - PD blower
The most common motor start is what is commonly known as “across the line” (direct) motor start. Power companies like when consumers do this as the resulting power draw (Amperage) spike is typically assessed with so called power demand charges on top of the regular power consumption charge in cents/kWh. In any application where the blower or compressor must start against header pressure this starting method carries the greatest penalty as the motor must overcome the rotating equipment’s moment of inertia and the system pressure. The graph below illustrates the power draw and the time it takes to bring the blower / compressor on line. An Aerzen Aeromat automatic start-up unloading valve may be the answer to your problem.

Of Pipework And Other Surprises During Blower And Compressor Start-up
Day of start-up is always an exciting time as all the long hard work of engineers and construction folks can finally show off what they have worked on for typically a long time. Most focus is placed on equipment, infrastructure, controls and plant processes. One item that is often underestimated in air and gas moving equipment is the pipe-work that connects primary air movers and the process. Materials of construction, alignment, thermal growth allowance and most of all cleanliness continue to be one of the most unique challenges start-up engineers continue to encounter.
