Engineering Sales Associates Maintains Production with Preventive Maintenance

By Arthur Pue, President, Engineering Sales Associates 

Preventive maintenance is seldom newsworthy inside manufacturing facilities. By design, preventive maintenance should be a non-event. Production keeps running, shifts continue to change, trucks are reloaded and unloaded and work goes on. The reliability of a compressed air system requires focus, attention and discipline: paying attention to variables, detecting patterns and knowing when something seems amiss. Looking deeper into system performance turns routine maintenance into a strategic tool for improving reliability and production stability.

Advanced Compressor Technologies Solves Oversupply Problem

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine 

A Southern Indiana office furniture plant was wasting hundreds of dollars per day because its oversized VSD air compressor could not turn down low enough to match reduced demand after a shift to metal fabrication. To avoid drive faults, the plant vented compressed air to create false load. The audit revealed 300 cfm of wasted air—about $400 per day—and led to a redesigned system using a fixed-speed compressor for base load and a VSD unit for trim. The new configuration eliminated artificial demand and cut compressed air energy use in half, setting the stage for further savings through advanced sequencing, storage, and demand control.

The Business Case for Air Compressor Rentals and Air-Over-the-Fence

By Matt Piedmonte, Vice President and General Manager, Americas, Aerzen Rental Solutions

There is no single right approach to putting the necessary volume and pressure of air in the pipe to meet production needs. There is a place for purchasing assets, there is a place for renting assets and there is a place for an AOF contract. Just as the business models around these assets change, so do the needs of an industrial plant. This article aims to explore these options and explore some of the pros and cons associated with different methods.

Texas Recycling Plant Saves Water with Air-Cooled Air Compressors

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

There are multiple compressed air applications in a waste management facility. This new recycling center uses laser-guided optical sorters to divide waste, with no human involvement on the sorting line. Laser optics determine what type of material each scrap is, then compressed air jets maneuver each piece to its collection area. Compressed air also powers handheld blow guns used for cleaning, as well as the bundling and packaging system.

The Case For Low Horsepower, Two-Stage Rotary Screw Air Compressors

By Ed Maxwell, CEO, Eastern States Associates

The isentropic efficiency of single-stage rotary screw air compressors, as reported by CAGI data, typically falls between 65% and 75%. Since isentropic efficiency is the ratio of ideal work to actual work, this range suggests these air compressors consume roughly 33% to 54% more power than the theoretical minimum for the given air pressure output. Much of the discussion in this article is theoretical since low-horsepower two-stage air compressors are new to the U.S. market.

Danmar Industries Custom Engineers for Oil and Gas

By Troy Dreier, Senior Editor, Compressed Air Best Practices® Magazine

The items included three 550 horsepower (hp), oil-flooded, water-cooled, single-stage air compressors with inlet valve modulation capable of providing 1,540 scfm at 165 psi (11.4 bar), two heatless desiccant, 3,138 cfm, 165 psi (11.4 bar) compressed air dryers, and two nitrogen generators for the main station, as well as two smaller air compressors and heatless desiccant compressed air dryers for each of three smaller facilities. Air compressor packages typically meet API 619, but the customer did not request that in this case. The motors, however, need to meet API 547. Air compressor system piping needed to be carbon steel built to ASME B31.3.

Blue Mountain Reins in a Sprawling Compressed Air System

By Ken Morris, Service and Sales Consultant, Blue Mountain Air Compressor Services

The plant was intermittently operating a staggering 11 air compressors scattered across its facility. Its system was a patchwork of different air compressor sizes and technologies, including two 25 hp fixed-speed rotary screw air compressors, one 30 hp fixed-speed rotary screw air compressor and one 100 hp fixed-speed rotary screw air compressor as its primary air compressors. It also kept several 15 to 50 hp reciprocating air compressors on standby, turning to them when primary units were down for maintenance.
