Fouled Heat Exchangers? Try Electronic Water Treatment

ProblemWhen material deposits form on heat-transfer surfaces, fouling occurs. Common fouling mechanisms include particulates, crystals (usually calcium carbonate), biological organisms, chemical reactions and corrosion. Fouling significantly impacts the thermal and mechanical performance of heat exchangers by increasing overall thermal resistance and lowering the overall heat-transfer coefficient. It also impedes fluid flow, accelerates corrosion and reduces […]

State-of-the-Art Control: Save Energy As You Maintain Normal Motor Speed

ProblemElectric motor efficiency, as stated by the manufacturer, often puts customers and operators at ease assuming that a 70% or higher efficiency DOES NOT waste much energy. What many users don’t realize, however, is that electric motors only achieve the rated efficiency when operated at 100% of rated horsepower.

Motor Shaft Voltages Kill Bearings

Problem Variable frequency drives (VFDs) make commercial HVAC systems, automated assembly lines and other processes more energy efficient. But they induce currents that can damage motor bearings. The resulting downtime and costly repairs can wipe out energy savings and severely diminish the reliability of an entire system. Now, with the AEGIS® Shaft Voltage Test Kit, […]

Better Inventory Management Helps Cut Operating Costs

ProblemA study conducted by Grainger’s Consulting Services estimates that more than half of U.S. businesses aren’t effectively managing their maintenance, repair and operating (MRO) supplies, leaving them with dead, obsolete and budget-draining inventory. In 2012, U.S. businesses are expected to spend approximately $110 billion on MRO items—ranging from light bulbs to cleaning supplies to nuts and bolts—and more than $12 billion of it will never […]
