In the foothills of the Andes, among the sprawling vineyards of picturesque Mendoza, Argentina, stands an innocuous equipment cabinet located by the side of an infrequently used mountain pass. The cabinet's superficial surface rust belies its importance as one of the most significant technological developments in modern day corrosion prevention. The cubicle, battered from years of an abrasive cocktail of arid Patagonian winds and coarse earth, hides the cradle of a revolutionary approach to cathodic protection. The equipment within the cabinet resulted in an entirely new range of products.

Picture a manufacturing enterprise with plants in multiple locations around the world. Using a single automation platform that handles discrete, process and motion control with common programming, human machine interface (HMI) and standards-based networks, a night shift operator gathers and logs data on product quality from his production line.

There are several ways to control two identical, parallel pumps operating under variable frequency control in pumping applications.

The service department of a variable frequency drives manufacturer frequently sees the following scenario: A frustrated user calls with what he perceives to be a defective piece of equipment. As the technician begins probing for information, the user's frustration boils over, often with an exclamation along the lines of "what a piece of junk!" As the service technician asks the pertinent questions, the exasperated user relays the details of a drive that is continually tripping on a fault until the user is at the end of his rope, not knowing what to do.

Lift stations can be difficult and costly to monitor, especially when the stations are located in remote areas.

Traditionally, the primary use of drives has been in applications such as powering pumps, fans and conveyors. While they will continue to be used in these applications, today's end-users have a different approach from that of a decade ago.

Wireless technology has significantly impacted business worldwide. It enables a greater degree of connectivity among devices for enhanced monitoring and utilization of existing assets. It has also led to the development of new applications that improve productivity, uptime and overall business performance.

Economic pressures to minimize production downtime and improve operating efficiency are increasing the emphasis to accomplish on-site problem detection, analysis, and resolution as fast as possible. These requirements place a great deal of pressure on maintenance personnel to have all the right tools readily available in one place.

Lubricated machines require clean, dry oil to work properly.

A Nashville-based hunting club required the flooding of several acres of land. A shallow area approximately 1.5-ft deep needed to be flooded to help attract wild game.

Wireless technology is enabling INEOS Köln GmbH (Cologne, Germany) to detect blocked filters in polyethylene pellet transportation tubes that can lead to production downtime at its plant in Cologne.

This article explores the use of condition monitoring at the UPM-Kymmene's Wisaforest pulp and paper mill in Finland. Production capacity is 800,000 air dried tons per annum (ADt/a) of pulp and 180,000 ADt/a of kraft and sack papers.

Control panel products enhance smooth operations.

The level transmitter is a small but vital component in a sewage lift or pump station that helps maintain system integrity and avoid unwanted spillage.

Explore differential pressure, electromagnetic, vortex and swirl, and variable area (rotameters).

On July 16 last year, a high-speed centrifugal pump failed catastrophically at a large refinery in South America, causing production losses and costing a substantial amount of money for repairs. The inboard bearing of the pump lost lubrication, overheated, and seized up.

The town of Walden rests on a high glacial plain in Colorado, just 20 miles from the Wyoming border in Jackson County. Situated in the center of a large open valley called North Park, the 734 residents (based on the 2000 census) of the town and the surrounding area refer to themselves as "North Parkers."

Here is a primer on the proper locations for surge protection in water and wastewater facilities.

If pump cavitation is not detected and quickly eliminated, significant damage can occur to the impeller and other internal components. Since cavitation (the formation and collapse of vapor bubbles in the pumped fluid as it passes through the pump impeller) is often temporary or even induced by the process, timely knowledge of the condition is extremely important so operators can act to alleviate the problem and prevent damage.
