By Ron Marshall The short answer is “as cool as possible, but not below freezing.” The practical answer is uncomfortably cool, in the range of 50° to 60° F. Keeping the temperature low reduces the amount of condensed moisture in the discharge air and makes things easier for the air dryer. Compressors generate significant heat […]

A compressed air auditor was performing his work at a large mining operation. He and the site electrician were opening up the various machine electrical panels to enable power factor testing. Within seconds of opening one compressor panel, the electrician jumped back with fright and informed the auditor he was going to be a while. […]

When working with desiccant-style compressed air dryers, there are several factors to consider, to ensure optimal performance and efficiency. Desiccant dryers rely on two towers filled with desiccant material that alternately dry the air and regenerate, to maintain continuous operation. The regenerative purge is essential to removing the moisture collected by the desiccant, but it […]

Preparing an industrial compressed air system for cold winter conditions is essential to ensure reliable operation, prevent equipment failures, and avoid costly downtime. Cold weather introduces unique challenges, such as moisture buildup, freezing, and increased system stress — all of which must be addressed to keep the system running efficiently. Proactive preparation can safeguard your […]

When performing leakage detection on your compressed air system with your ultrasonic leak detector (if you don’t have one, good grief, run out and get one!), you will run across various leaks in piping and equipment. Many of these are small, so roughly less than $100 value per year. But quite often, you will find […]

Do you know how much air your compressed air system is consuming? How about the level of waste during non-production? If you don’t, it may be time to purchase a flowmeter to find out the answers to these questions. Recently during a leak assessment, a compressed air auditor was surprised to see 46 cfm flowing […]

The typical piping installed in industrial plants and shops is made of steel, and as a result may be subject to rusting and contamination. Fig. 1 and 2 show what was found at a heavy industrial plant with the air compressors taking in polluted air. Rusting and contamination in compressed air system piping can lead […]

Normally when measuring the pressure gradient of a compressed air system in an industrial site, the pressure at the compressor discharge is the highest of all locations. Once the compressed air travels through piping, filters, air dryers, and other components — each causing restriction to flow — the pressure at the far end of the […]

I found a leak, it’s hissing loud, Compressed air whistling, oh so proud. I grabbed some duct tape, rolled it tight, Thinking I’d fix this leak tonight. But oh, that tape — it flaps and flails, Like it’s on a ship with stormy sails. The air just laughed, a mocking squeak, “You can’t fix me, […]
