Peer reviewed article:
"The cost and schedule impacts of delaying investment in hydropower equipment to the point of failure can be severe. In fact, according to the results of a recent survey, costs can be 10 times higher than making the investment in advance of the failure."

10 Cooling Tower Maintenance Tips

Air Conditioning, Heating, Refrigeration News, June 22, 2015, by Baltimore Aircoil Co.
http://www.achrnews.com/articles/129904-cooling-tower-maintenance-tips

"A well-maintained unit will continue to function at the original optimum efficiency. Over time, a neglected cooling tower’s leaving water temperature will increase, raising energy costs by up to 6 percent for every 2°F increase. However, a well-maintained cooling tower will continue to function at the original optimum efficiency, keeping energy costs low. These simple preventive cooling tower maintenance tips can help users save up to 15 percent on electricity costs. Routine maintenance also helps to conserve water and extend the operating life of cooling equipment."

Plant Engineering: Lubrication Guides

Plant Engineering, June 2015.
http://www.plantengineering.com/advertise/lubrication-guide.html

"Friction is the enemy of efficiency. A sound lubrication strategy is essential to keep all the gears in your operation running at their best. The emergence of synthetic lubricants has helped improve the performance of machinery and has become an important part of any maintenance manager’s arsenal in the fight against friction.

The Guide will provide you with a comprehensive look at the available lubricants. This year's guide also considers the important issues of environmental impact of oils, greases and fluids, the need for a strong culture of lubrication excellence, and an in-depth look at some of the new standards in bearings and seals."

Safety and Energy-Saving Resulting from Early Detection and Prevention of Leakage of Low-Flammable Refrigerants

IEA Heat Pump Centre Newsletter, #33 2015, by Masahide Sumi. [Open PDF then scroll or jump to page 22.
http://etkhpcorder.extweb.sp.se/ViewDocument.aspx?RapportId=1267

"Leakage of refrigerants represents a high cost in terms of the energy required in refrigeration and air conditioning devices. As it is expected that low-flammable refrigerants will be used in many devices in the future, this issue can be very important for the global environment, energy saving and safety. The following article describes detection systems which can easily detect and identify leakage at an early stage, and a method which can easily prevent leakage from plumbing and joints of air conditioning equipment."

Maintaining Modular Conveyor Systems in Flexible Manufacturing Systems

Maintenance Technology, Mar. 2015, by Paul Zielbauer.
http://www.maintenancetechnology.com/2015/03/maintaining-modular-conveyor-systems-in-flexible-manufacturing-operations/

"Pallet-based modular conveyors used in flexible manufacturing provide a wealth of benefits in just about any assembly operation. Suitable for applications ranging from small electronic parts assembly to large appliance manufacturing, automotive drivetrain and even medical-device assembly, these conveyors help improve production, achieve higher product quality and enhance manufacturing flexibility. Regularly scheduled maintenance and attention to detail are crucial for ensuring the longevity and efficiency of these systems."

Question Everything When Replacing Commercial Boilers

Engineered Systems, Jan. 2015, by Ray Wohlfarth.
http://www.esmagazine.com/articles/96929-question-everything-when-replacing-commercial-boilers

"Although the majority of the boilers have been installed properly, there have been many that were not. Those boilers that were not installed correctly would have been very costly to fix had we not seen the issues prior to installing the new ones. Any issues with the heating system become your issues once the new boiler is installed."

7 Fundamentals of Green O&M

Buildings, Oct. 2014, by Jennie Morton.
http://www.buildings.com/article-details/articleid/18020/title/7-fundamentals-of-green-o-m.aspx

"Opportunities to run your facility in an environmentally conscious manner abound. Everything from product procurement, cleaning, and waste management to water efficiency, landscaping, and daylighting can and should be driven by sustainability. But with tight budgets and competing interests, keeping green at the heart of your operations is challenging. And no matter how eco-friendly your building’s design is, there’s always room for continuous improvement on the O&M side. We’ve found seven key areas that should be part of any green operations plan."

Prepare Your Renewable Plant for Cold Weather Operations
