Industrial Utility Efficiency

Transit

In the absence of the control system, the air compressors were loading and unloading according to pre-set pressure bands, which forced the system to operate at higher pressures and run inefficient combinations of compressors in order to effectively match air demand. When switched on, irrespective of air demand, the control system was able to control all compressors on a single, tight pressure band and efficiently match output with demand.

New York City Transit Authority Reduces Energy Use with Compressed Air Heat Recovery System

When the New York City Transit Authority (NYCT) set out to comply with local regulations calling for reductions in energy usage, it leveraged new air compressors for use in transit bus maintenance and repair – and took things to another level by recovering air compressor waste heat to provide hot potable water for the bus depot. The air compressor and heat recovery system, installed in spring 2017, is on its way to helping NYCT achieve the best energy savings possible.

Power Supply Industries Helps Alton & Southern Get Back on Track

Their job is to brake the cars by gripping the wheels. They are operated either pneumatically or hydraulically, with Alton & Southern Railway’s system using the former. Considering much of Alton & Southern Railway’s compressed air piping system dated back to its 1960’s installation date, there were leaks. As of 2012, it was determined one and a half compressors were running at 100% capacity just to maintain leaks. This equated to about 1,500 cfm at a cost of roughly \$180,000 in electricity annually.

ELGi Compressors USA at HAECO Americas

In aerospace manufacturing, tiny details matter most. For instance, if proper torque is not applied to the screws and bolts fastening an aircraft fuselage, catastrophic failures can result. Compressed air is used to power the tools needed to apply that torque, making the compressed air system a critical part of the facility, though it largely stays behind the scene.

Boeing Canada Winnipeg Recognized for Compressed Air Project

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.

Universal Air & Gas Products Engineers NGV Refueling Stations

When a submarine docks for maintenance, the Navy requires a high-pressure, dockside, pier-power air compressor ready to be used in an explosion-proof environment. We have technicians working on military ships and submarines worldwide. For this, both UAPC and some of our technicians have been prequalified and have different secrecy clearances depending upon the project. In addition to our rental air compressors, we also have a fleet of CNG compressors available for long-term rent for the CNG refueling market.

Natural Gas Dehydration and Conditioning for NGV Refueling and Field Gas Upgrading

Compressed Natural Gas (CNG) is an alternative fuel source (to diesel and gasoline) with far-reaching benefits to North America. Strategically important benefits include energy independence, improved air quality, job creation, and lower and more stable fuel prices. This article discusses natural gas desiccant dryer requirements in Natural Gas Vehicle (NGV) refueling stations, compares deliquescent to desiccant dryers and reviews two on-site field gas upgrading examples in displacing diesel fuel.

Smith Electric Trucks Complement CNG

Smith is one of the world’s leading manufacturers of all-electric commercial vehicles, which are zero-emission and less expensive to own and operate when compared with traditional diesel trucks. The company produces trucks for multiple industries, including food & beverage, utility, telecommunications, retail, grocery, parcel and postal delivery, school transportation, military and government. Smith’s customers include many of the world’s largest fleet operators, including PepsiCo’s Frito-Lay division, FedEx, Staples, TNT, Sainsbury’s, Coca-Cola, DHL, and the U.S. Military.

How to Avoid the Most Common Bus/Coach Kneeling Failures

Kneeling modules are quickly becoming the centerpiece of accessible vehicle equipment. This trend began with passage of the Americans with Disabilities Act (ADA) in 1991. Prior to the ADA, about 40% of all transportation vehicles were accessible to persons with disabilities.

Audit Savings for Motor Coach Industries

Motor Coach Industries, headquartered in Schaumburg, Illinois, is the largest manufacturer of intercity tour coaches for the tour, charter, line-haul, scheduled service, commuter transit and conversion markets in the U.S. and Canada. The company operates a four screw-type air compressor system at its Clarence Avenue plant in Winnipeg. To maintain adequate system pressure at the plant, Motor Coach was forced to run all four compressors 24 hours a day, seven days a week.
