# System Assessments

Analysis of the pressure data logging showed that, while the variable speed drive compressor maintained a constant discharge pressure near 120 psi, the pressure at various critical points fell to as low as 85 psi during peak production operations. General pressure in the plants, especially Plant 2, fluctuated between 102 and 112 psi, showing that the pressure/flow control valve was not regulating properly, and that Plant 2 lacked enough general storage volume to support transient flows.

## Compressed Air System Drawings: A Picture Can Save Tens of Thousands of Dollars

There are some fundamentals when it comes to compressed air system improvements. One strategy that is overlooked is just drawing the details of whatever aspect of a system you are looking at. It is fairly common to see a misdiagnosis of some particular technical issue that would have been obvious should someone have created the drawing to describe the problem.

## The Fundamentals of Dew Point Measurement in Compressed Air Systems

Dew point is simply the temperature to which air must be cooled for the water vapor within to condense into dew or frost. At any temperature, there is a maximum amount of water vapor that the air can hold. This maximum amount is called the water vapor saturation pressure. If more water vapor is added beyond this point, it will result in condensation.

## Maintaining Compressed Air Filters and the Purpose of Differential Pressure Monitoring Devices

The foundation of any purification system is its filtration and of the ten main contaminants found in a compressed air system, filtration is responsible for the treatment of nine of them. Coalescing filters are the most important piece of purification equipment as they reduce six of the ten contaminants and a look in any air compressor room will find a pair of coalescing filters (backed up with dry particulate and oil vapor removal filters).

## Adsorbents for Heat Reactivated Compressed Air Dryers

In the field of externally heated adsorption dryers there is a large variety of different systems on the market offering substantial flexibility in terms of process flows, dew points and energy demand. Often, economic parameters and project-specific requirements ultimately define the individual user-specific solution. This article discusses the basic types of desiccants used in compressed air dryers.

## Is Your Controller a Blast From the Past?

Advances in phone technology dramatically improve their function and our experience. More storage, faster speeds, enhanced communication options, bigger and brighter display….and so on. As a result, today’s phones are significantly more powerful – improving our productivity and changing our lives. As for the technology laggards, obsolescence eventually prompts change. Repairing or replacing parts and accessories on the old phones is an increasing challenge. Eventually they have to succumb to technology.

## How Your Air Receiver Tank Improves System Efficiency - Part 1

An air receiver tank (sometimes called an air compressor tank or compressed air storage tank) is a type of pressure vessel that receives air from the air compressor and holds it under pressure for future use. The tanks come in a range of sizes and in both vertical and horizontal configurations. An air receiver tank provides temporary storage for compressed air. It also helps your compressed air system run more efficiently.

## Compressed Air Manufacturers and Distributors Rise Above the COVID-19 Crisis

As the crisis unfolded, manufacturers and distributors of compressed air and vacuum systems took the necessary steps and precautions using guidance from the Centers for Disease Control and other agencies to minimize the spread of the virus, while continuing to support customers. At all times the top priority was the safety and wellbeing of employees and their families, as well as partners and customers.
