By Ron Marshall The pressure vessel authorities in your state or province have set rules for the installation of pressure vessels. Like most regulations these rules have been put in place because someone has been killed or badly injured in the past by an unplanned explosion caused by a failed pressurized device. Sometimes plants install […]

By Ron Marshall A newly constructed manufacturing plant had a policy to always install high quality pressure regulators for each one of their thousands of production machines. Each regulator was adjusted to the machine input requirements — and the pressure gauge marked it indicate the allowable range of adjustment. Despite this effort, some production machines […]

Unplanned plant shutdowns are a killer on the bottom line, requiring lots of patience and the use of scarce reserve funds. As with anything, the pain is rarely permanent, and the most we can do is grin and bear it — and also try to keep ourselves productive. It is a time for future planning […]

By Ron Marshall A food processing plant invited a compressor vendor in, to conduct a compressed air assessment. The goal here was to determine the plant’s system efficiency for a possible compressed air improvement project. The vendor placed data loggers on the compressed air system to measure the plant pressure and power. The data logging […]

There is always much talk about the need to fix compressed air leaks and inappropriate uses in a plant — but sometimes the wasted flow is hidden inside components such as compressed air desiccant dryers. A small chemical processing facility is located in an area of the world where temperatures in winter drop down below […]

Heat is not the friend of any compressor. Overheating can shut down your compressor, cause excessive water and oil to pass downstream, can kill air dryers, and prematurely age system components. For this reason, it is a good maintenance step to monitor the temperature at various points in the system. This can help you flag […]

A medium-sized tire shop was having troubles with pressure during their busy times. In the spring and fall, during agricultural planting season, the pressure went way down when servicing the many farm implement tires coming in. And the shop’s compressor would cut out when they needed it the most — a very frustrating experience. A compressor […]

Compressor rooms are usually dirty, dusty places that take care and attention to keep clean. It’s not that the compressor operators are slobs, it’s that the air compressors must suck in surrounding air to work and to keep cool. This creates a negative pressure around the compressors that draws in anything airborne. The photograph shows […]
