Compressed Air Challenge: Maintaining Peak Compressed Air Efficiency

Maintenance Technology, Sept. 2014, by Ron Marshall.
http://www.maintenancetechnology.com/2014/09/compressed-air-challenge-maintaining-peak-compressed-air-efficiency/

"A well-maintained [compressed air] system will provide an uninterrupted supply of cool, clean and dry compressed air at a stable and appropriate pressure in the most efficient manner possible. Poorly maintained systems have frequent system shutdowns, heat or moisture problems, exhibit system pressures that fluctuate wildly at levels that are too high to produce efficiently, and typically waste air due to leakage.  ...here are several key maintenance-related points to consider for trouble-free compressed air system operation."

"If you want to make a plant manager’s day, just say: “Production’s down because a motor failed.” Fortunately, such situations can usually be overcome with some relatively simple techniques and straightforward solutions to protect the bearings and stator windings. These two vulnerable components are root causes of the vast majority of motor failures."

What Owners Need to Know About ... Evaporative-Cooling Equipment

Heating/Piping/Air Conditioning Engineering, Apr. 2014, by June Galloway. (Free registration is required to view full-text of article.)
http://hpac.com/air-conditioning/what-owners-need-know-about-evaporative-cooling-equipment

"Evaporative-cooling equipment is selected to provide a fluid (usually water) to a system at a certain temperature and flow rate. If the temperature of the fluid delivered to a system (chiller) is higher than desired, the system will suffer increased wear and tear and usage. Decreasing leaving-water temperature by just 2°F can lower electricity expenditures by 6 percent.

Routine inspection and maintenance is paramount in achieving desired temperature and flow rate, and it plays an important role in extend operating life
