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.
EnergAir’s unrivalled expertise in compressed air management is helping to save in excess of $50,000 per year at Whirlpool Corporation’s Ottawa, Ohio production facility. Whirlpool is the largest global manufacturer of home appliances and employs almost 70,000 people in more than 60 production and technology centres around the world. The Whirlpool plant in Ottawa manufactures a market-leading range of trash compactors, chest freezers, upright freezers and refrigerators.
Compressed Air Best Practices® Magazine interviewed Pascal van Putten (CEO) of VP Instruments. We founded VP Instruments, in 1999, with the mission being to apply our experience with flow sensor technology to compressed air and gas flow applications in laboratories with a “one size fits all applications” concept. We did some trade shows and sold one unit during the first year – a tough start. So we hired a consultant who helped us re-package the technology completely. This led us to launch the VPFlowMate, in 2002, in a small and easy to use package. The company has taken off since then.
Productivity is more reliable when equipment can be monitored to detect incipient failures and take corrective action before the plant goes down. But many devices, such as analog control valves, pneumatic valve terminals and field sensors, often do not offer diagnostic feedback, or it is not being used. This white paper describes how this problem is being addressed, and includes an example of pneumatic valve terminals that can monitor, among other things, open load or coil currents at the specific valve and pressure inside the valve terminal.
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.
Compressed Air Best Practices® Magazine interviewed Frank Mueller (President) and Stephen Horne (Blower Product Manager) from Kaeser Compressors. Kaeser Compressors continues to grow both in the U.S. and internationally. We currently employ approximately 4800 people globally. In order to support the demand and maintain our superior quality and quality service levels, we continue to invest in people, facilities and technology.
As the population continues to grow in the United States, industrial water use will need to continue to fall to help offset the increases in public-supply water use. Water-cooled compressed air systems provide an opportunity for sustainability managers to reduce associated cooling water consumption and costs. If switching to air-cooled air compressors is not possible, understanding the costs and the alternative types of liquid cooling systems is important.
Compressed Air Best Practices® Magazine interviewed Dr. Jay Varadaraj, (Managing Director) of ELGi Equipments Ltd. ELGi today is one of the world’s leading manufacturers of air compressors. Like most companies, however, it started with one ambitious person. My grandfather, Lakshminaickenpalayam Govindaswamy (this where the “L” and “G” in ELGi come from) was a bus driver for the British in 1918. He purchased one bus and proceeded to build a fleet peaking at 300 buses. He believed he was in the transportation business so he entered the airline business ultimately withdrawing however when this industry was nationalized.
The compressed air system in most industrial and commercial facilities is vital to production machinery and processes. When it goes down so does the plant output. This important utility is often one of the most costly energy consumers in a facility. Yet most compressed air system operators have little knowledge of how their compressed air system is performing and, if problems have happened, do not have an accurate record of what went wrong.
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?!
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.
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.
