Demand Dry Storage Part II: Application and Use in an Efficient Compressed Air System

In continuation of our series examining the application of storage in a compressed air system, this article will focus on another type of supply side storage concept: demand (dry) storage. Before discussing the definition, application and use of demand storage, I would like to reiterate that contrary to current thought, consideration should be given to control (wet) and demand (dry) storage being separate storage solutions based on their primary purpose.

Industrial Oil-Free Air Compressors: Why They Are the Best

There is an old adage which is also a law of physics; what goes in will eventually come out. This applies to compressor lubricant in oil-flooded rotary screw compressors. At a rate of 2 ppm carryover, an oil-flooded 100 hp compressor operating for one year (8000 hrs) will introduce over 4 gallons of lubricant into a compressed air system. Eventually, this lubricant will drop out.

Control (Wet) Storage – A Misunderstood Concept in Compressed Air Systems

When evaluating a compressed air system and the proper application of storage, one of the most misunderstood concepts is control storage. It is often referred to as wet, primary, or in some cases demand storage; however, the term control storage is more reflective of its main function – to maximize the effective operation of the compressor control. For the purpose of this article, I have limited the definition of control storage to; any storage created between the air compressor discharge and before any cleanup equipment, i.e. filters and air dryers. While one can argue that control storage shares some commonality of purpose with the more commonly applied demand (dry) storage (storage created after cleanup equipment and before demand regulation), it differs in the location of the storage and its functionality. It is not that unusual in compressed air system design to integrate both control and demand storage taking into account the primary function of both.

Condensate Drain Systems: The Most Vulnerable Point of a Purification System

Where there is compressed air, there is water. Condensation is the moisture that drops out of an air flow as it cools and is therefore a constant threat to cause expensive problems in a compressed air system. Condensate drains are necessary to keep water, dirt, wear particles, bacteria out of your system. The problems get worse if you operate lubricated reciprocating or oil flooded rotary screw compressors – which is just about everyone. Compressor oil makes its way into the distribution system with the compressed air. The mixture of oil, water, and dirt tends to build up a sludge that will ultimately jam or clog production equipment, air tools and drains.

Oil Sealed Liquid Ring Vacuum Pump Solutions: Pros and Cons

Get maximum reliability under the toughest conditions

Oil-sealed liquid ring vacuum pump systems give maximum reliability under the toughest conditions. These highly efficient systems are known for their simplicity in design and low maintenance requirements due to the absence of wearing parts. Compared to other vacuum pump systems, these systems offer advantages of no metal-to-metal contact between the impeller and casing and also require no internal lubrication. By using specially formulated low vapor pressure sealing fluid, they can operate up to 10,000 hours or more without an oil change, while preventing corrosion and scale build-up. An additional advantage of oil-sealed systems is that the use of water – and the corrosion and waste associated with it – has been completely eliminated. The air/oil separator virtually eliminates oil carryover concerns and ensures the cleanest environment. Switching from water cooled to air cooled will also produce significant cost savings on water usage and reduce groundwater runoff contamination.

Compressed Air Drying Equipment: Lower Costs With the Right Dryer

Why the Regenerative Dryer Might be the Best Option for You

It has been well documented that the presence of water in compressed air systems can have serious ramifications. Consider this: a typical 100 hp compressed air system at common ambient conditions can generate as much as 40 gallons of water in a 24-hour period. As a result, industries lose millions of dollars each year from lost production, increased maintenance costs, and a reduction in quality.

Centrifugal Air Compressors: The Best Kept Secret In Compressed Air

When it comes to deciding on air compressors, most people look at rotary screw types that are either lubricated or non-lubricated. This is justified when the horsepower of the compressor falls between 10 and 250 hp, but what about when the compressor is at or above 250 hp? Is the rotary screw the air compressor of choice or are there other options available?

Does your facility’s fluid cooling system really require chilled water?

Over the last 25 years there has been a heightened awareness to reduce the consumption of both water and energy. Federal, state and local laws, rising costs of water and energy, and a growing need to reduce operational costs have pushed this awareness to the forefront of all industries. Most companies are trying to cut expenses and become more efficient. It’s smart business and it’s urgent.

Air Compressor Controls Result in Reduced Energy Consumption

Innovation + Imagination = FLO-TROL

The Department of Energy has estimated that 10% of all electrical energy use in the United States is consumed in the generation of compressed air. This has added significance since 70% of all manufacturing facilities utilize compressed air in some aspect of their manufacturing process. These facts highlight the reason why companies with compressed air systems have a compelling reason to investigate the potential for energy savings.

Compressed Air Product Design Helps Airborne Get Off the Ground

JHF becomes engineering tool for Airborne Athletics

In 1997, Doug Campbell and his brother Jeff decided to start their own business. Doug was an avid volleyball player and wanted to develop a product that would provide him with a convenient way to train on his own. Doug asked Jeff for his engineering expertise and together in their garages they designed a volleyball throwing machine called AirCAT. The Campbell brothers knew that other volleyball machines existed but most lacked consistency, caused ball wear, and none were operated with the help of an air system. This was the beginning of Airborne Athletics.
