Industrial Utility Efficiency


The current cost to operate the compressed air system is \$139,100 annually, and the proposed measures will reduce it by \$50,700 annually. The proposed cost to complete the measures is $47,600 providing a simple payback of 11 months. The cost included in the Action Plan includes engineering, project assistance, services to maintain the gains, and a 10% contingency.  

Hoffman Revolution Blower Continues Tradition of Innovative Design

The Hoffman U.S. Machinery Division was established in 1905 outside of East Syracuse, New York. The initial product was an exhauster for the dry cleaning industry — pulling a steam vacuum across the garments. The Company grew and soon after began discovering industrial applications for their technologies. After the war period, during which Hoffman manufactured ball bearings and operated it’s own foundry, the company began discovering new industrial markets for it’s products. A significant part of their business was in the wastewater treatment industry.

Energy-Savings at Milk, Cheese, and Ice Cream Plants

Compressed air system refinements have cut operating costs at a Milk Plant located in Winnipeg Manitoba, Canada by 62%, for annual savings of nearly \$30 000. The improvements were made following a compressed air audit that recommended consolidating two compressed air systems into one, installing a variable speed drive compressor, and making a handful of additional basic improvements.

Improved Modified Atmosphere Packaging Technology

CVP System, Inc.’s MasterPACKer Eco+™ Breaks Down Barriers to Cost and Energy Savings Through Improved Modified Atmosphere Packaging Technology

Worldwide, Tesco, a global grocery and general merchandise retailer headquartered in Cheshunt, U.K., initiated the demand for modified atmosphere packaging technology in the early 70s. It became one of the first grocers to move away from employing an onsite butcher to using a central processing/distribution system.

Compressed Air Efficiency Opportunities in the Plastics Industry

As in most industrial categories, compressed air is critical to the operations of a plastics plant whether it is blow molding, injection molding, or other processes. The opportunities to improve supply side (compressor room) efficiency are similar to all industrial compressed air systems, but are even more prevalent in some plastics facilities, especially blow molding.

Double-acting Reciprocating Air Compressors for P.E.T. Bottle Blowing

Most P.E.T. bottle-blowing machines require anywhere from 550 psig (38 barg) to 580 psig (40 barg) and an air flow of 247 cfm FAD (420 m3/hr) to 3700 cfm FAD (6290 m3/hr). The air compressor technology used most prevalently for this application is the double-acting, oil-free, water-cooled, reciprocating air compressor. With the higher pressures and air flows that are required, the P.E.T. bottle blowing market is a strong niche market for the double-acting oil-free reciprocating (piston) compressors.


Energy Management at Visteon

There are three main segments in Visteon's climate group are climate systems, powertrain cooling and engine induction. Climate systems include refrigeration compressors, fluid transport, heat exchangers, battery cooling modules, climate controls, auto defog/demist systems, and multi-zone HVAC systems. Powertrain cooling systems include heat exchangers (radiators, condensers, charge-air, exhaust-gas), airflow management, and diesel and hybrid thermal management. Engine induction includes air induction systems and intake manifolds.

Sanity Check: Will the Standby Air Compressors Start-Up During Cold Weather?

Several days prior to our visit, during a cold winter evening, the lead air compressor in one mechanical room tripped off (apparently due to a fouled intake filter and low air flow through the machine). A crucial situation then developed: The "stand-by" unit did not start. Maintenance folks had to be called in to get a compressor running. That delay caused low plant air pressure, production curtailment and some defective product. They had yet to determine the conditions that caused the "no-start".

A Compressed Air Checklist for Waterborne Paint Conversion

Encouraged by government regulators, the conversion to waterborne paints is now moving into the collision repair and refinishing industry. The conversion to waterborne paints is proving to have implications for the compressed air systems in the shops. This document provides a checklist of compressed air system topics to ensure a successful conversion to waterborne paints.

The Benefits of On-site Nitrogen Generation

Nitrogen gas provides a number of diverse uses for a wide variety of manufacturers. As a sister function of compressed air, on-site nitrogen generation can provide additional opportunities for cost savings and other efficiencies for manufacturers who shift from delivered liquid nitrogen service.
