Variable frequency drives (VFDs) have become a preferred method of process control for electric motor driven equipment ranging from vertical water pumps to centrifugal air fans. The following is a basic discussion of risks of using a VFD with direct driven centrifugal fans and methods of mitigating those risks to maintain equipment reliability.

What is a thermal image?
Thermal images are created by converting thermal radiation into a visible light image that we as humans can interpret. One important point to remember about thermal imaging is that it is a non-contact measurement of radiated energy in a very narrow wavelength band.

Studies show that 50 to 70% of all equipment failures can be directly traced to a lubrication-related issue, most of which can be found with oil analysis.
Lubrication is vital to maintenance and reliability. Lubrication done right can alter the path of how asset reliability is managed. Understanding lubrication maintenance strategies and lubrication failure modes will allow key personnel to eliminate root causes to achieve operational KPI’s.

Businesses invest millions of dollars in what they believe will be a fail-safe maintenance program for their electric motors. Regular tests are scheduled for each motor; engineers dutifully record the data when required and then move on to the next motor.

Balancing cost reduction and efficiency improvement targets is a common source of frustration for maintenance and engineering managers. For facilities that operate continuously with no window for unplanned shutdowns, poor reliability and availability of machinery is far more serious, but even in factories with regular opportunities for maintenance, recovery can still be expensive and time consuming.

More than 300 million electric motors are used in infrastructure, large buildings, and industry globally. These motors account for about 2/3rds of the industrial power consumption. Electricity is required in almost all areas of the plant to provide the driving force that either operates the equipment that produces the products or provides the services that the plant’s equipment was built to perform..
