Most of us understand each individual has a unique DNA combination. Compressed air is very similar, each compressed air system should be uniquely designed so the system performs in harmony. Properly managing the compressed air system requires an investigative audit to understand the nuances of the system and identify the most effective solution(s) for efficiency. Not investigating the system, before selecting improvements, would be like consenting to surgery without having an exam. Yet, this frequently occurs in businesses operating compressed air systems.
Boeing Canada Winnipeg (BCW) has been recognized with the best improvement project of 2013 within the Boeing enterprise worldwide. A cross-functional project team including BCW staff, Manitoba Hydro technical support, and design engineers from Alliance Engineering Services, Inc. used innovative high-pressure storage to reduce the required size of their air compressors and save substantial utility energy and demand charges.
Types of Compressed Air Dryers Part 3 –Heat of Compression, Single-Tower Deliquescent and Membrane Type Dryers
A careful examination of a facility's compressed air system will likely reveal several opportunities to improve the performance of the compressed air system by effectively and efficiently removing moisture from the compressed air system. The Compressed Air and Gas Institute (CAGI) committed to issuing a series of articles discussing moisture in the compressed air system.
The 86th annual Water Environment Federation technical exhibition and conference, known as WEFTEC 2013, was held October 5-9 in Chicago’s McCormick Place. Show organizers reported record preliminary numbers with 22,598 attendees, 971 exhibitors, and a total net square footage of exhibit space of 297,400. As usual, I donned my “roving reporter hat”, took my “budget camera” and visited as many of the aeration blower vendors as I could.
This is a food processing plant where processes and standards are controlled by FDA to AIB standards. Annual plant electric costs for compressed air production, as operating today, are $116,765 per year. If the electric costs of $3,323 associated with operating ancillary equipment such as dryers are included, the total electric costs for operating the air system are $120,088 per year. These estimates are based upon a blended electric rate of $0.085/kWh.
For many industrial sites the only indicator of compressed air performance is the big old pressure gauge right outside the maintenance manager’s office. Over the years someone may have penciled a red line on the gauge, and if the pressure falls below the line the manager will start shouting. This is an example of the saying “ What gets measured, gets managed”, definitely the plant pressure in a facility is a very important indicator of adequate compressed air system operation, but is it the only parameter that needs to be monitored? This article explores some important compressed air KPI’s and provides some examples of how they can be collected and used.
The advent of manifold mounted, plug-in pneumatic valves has been a boon for machine builders. It allows them to mount complete valve packages in a safe and secure location on a machine. Using a D-sub connector, serial interface module, or similar single-point wiring system, all of the electrical control outputs can feed into one location on the manifold, greatly simplifying the wiring. Plumbing issues are reduced, since a single air pressure line can be used to feed a common pressure gallery. The same advantage applies to the common exhaust gallery. No longer would both a plumber and an electrician be required to replace a valve, since any valve can be replaced without disturbing electrical connections or plumbing lines.
It’s one thing to move materials during the production process, but when it’s a finished product on the packaging line, choosing the right material handling system is essential. Getting it wrong results in squandered production time when product loss occurs, and wasted raw materials.
There are six basic types of cooling systems that you can choose from to meet the cooling needs of your load. Each one has its strengths and weaknesses. This article was written to identify the different types of cooling systems and identify their strengths and weaknesses so that you can make an informed choice based on your needs.
The 2014 Association of Independent Compressor Distributors (AICD) Membership Conference & Exhibition
The “new AICD” needs large resorts now, like the Rosen Shingle Creek, as this event keeps growing in their second year of welcoming air compressor distributors and vendors - from any brand. Walking the show alongside the traditionally Quincy distributors, were Mattei, BOGE, Palatek, Ingersoll Rand and Gardner Denver (to name a few compressor brands) distributors. How can that be - I didn’t even see any fights or at least arm wrestling matches?!
Northwest Pump & Equipment was founded in 1959 - opening three branches on the same day in Portland, Seattle and Spokane. The business focus was to distribute petroleum equipment for the oil and gas market – primarily to service stations and oil jobbers. In-ground fuel tanks, hoists, lubrication equipment, lighting, farm pumps, air compressors and other gas pumping equipment were our primary product lines back when there were “Full-Service Gas Stations”. Over the years, this successful business model was expanded so the Company did business in California, Hawaii, Washington, Alaska, Arizona, Nevada, Idaho, and Montana.
Compressed air is used in a number of processes in the food industry. It is used as an ingredient in whipped products such as ice cream, to slice or cut soft products and to open packagesbefore filling of product. Currently, food manufacturers are under pressure to validate the safety of all ingredients or processes for regulatory compliance, but unfortunately, there is currently no standard method to evaluate the microbial content of compressed air.
Over many years of reviewing industrial compressed air production machinery, of many types and styles, there is one common thread or complaint; “push-to-connect pneumatic tubing connections/fittings are a continual source of compressed air leaks and production interruptions.” Probably seventy-five to eighty percent of push-to-connect type tubing fittings use flexible tubing selected for lower material cost and assembly rather than an alternate appropriate hard metallic tubing.
One type of dryer seen frequently across the world is the regenerative desiccant dryer. These dryers have a number of characteristics that can affect their cost of operation and the operating of the associated compressors and can therefore affect the efficiency of the complete compressed air system.
There are several pieces of information that your cooling system specialist will need in order to properly engineer and build a cooling system for your new air compressor. There are many types of air compressors and each has different requirements of the cooling system in order to operate correctly. This article will take the mystery out of some of the terms and specifications for your cooling system.
Nutriom sets the bar high when it comes to producing its premium quality natural powdered egg products Ova Easy® and Egg Crystals®, that are sold at outdoor retailers such as REI, and online merchants such as Amazon.com; so, when the screw conveyor in their FSIS USDA facility required regular unexpected attention, Leonardo Etcheto, Plant Manager at the Lacey, WA facility knew it was time to look for a better solution.
The development of extruded aluminum piping is a recent innovation in the compressed air industry. The internal bore of this piping is smooth and corrosion resistant which makes the pressure differential characteristics of a straight run of this pipe superior to that of steel pipe. Because it is much lighter than steel pipe the installation is much easier. And the manufacturers of this style of piping have come up with various twist lock connectors to make the installation even simpler.
This is a corn mill processing cornstarch, sugar, and other byproducts. Ambient air is contaminated with extremely high levels of dust due to the manufacturing processes and material handling. Average electric rates at the plant are $0.04 / kWh. The actual plant electric cost for compressed air production is $553,630 per year.
Specifying a control valve for Pressure/Flow Control service should be a relatively straightforward process. The range of compressed air flow and pressures must be known along with the target delivered air pressure. With this information, the performance specifications published by the various suppliers can be referenced for selecting a valve package. Often, however, the valve selected is too large in size to ensure it will have sufficient capacity to satisfy current and future flow requirements. Valve manufacturers use different design criteria in rating their units and in how their product is presented. There are no standards.
