Editor’s Choice Silver Bullet Water Treatment Technology Proven to Reduce Use of Water in Data Centers Silver Bullet has found that deploying its system in data centers dramatically reduces the chemicals used to treat cooling tower water. The process results in saving millions of gallons of water and tens of thousands of kilowatt hours of electricity, decreasing overall operating costs and increasing the sustainability of data center properties across the US. More than half of a data center building’s water use is from cooling towers, which provide cooled water for air-conditioning, manufacturing and electric-power generation. A typical 15-megawatt data center could use up to 360,000 gallons of water a day to keep servers and equipment cool enough to operate effectively. By targeting this component of building infrastructure for efficiency with Silver Bullet’s water treatment system, property owners can immediately realize savings in electricity, water, labor and maintenance. “The Silver Bullet Water Treatment system is a proprietary electro-chemical water treatment system that disinfects and conditions cooling tower water to virtually eliminate microorganisms and scale formation,” said Silver Bullet’s executive chairman, Robert Hanfling. “It was painstakingly developed by our chief technology officer, David Kolstad, following three decades of experience as an operating engineer in power plants, commercial buildings and hospitals. David’s hands-on work with traditional, chemical-based approaches to water treatment inspired him to develop a more efficient, lower maintenance and safer solution.” In a study conducted by the Dept. of Civil and Environmental Engineering at the University of Pittsburgh in 2012, the Silver Bullet system was found to kill 99.8 percent of bacteria in cooling towers; including greatly reducing Legionella bacteria growth, the cause of Legionnaire’s disease. Perhaps the most innovative feature of Silver Bullet over traditional chemical treatment of cooling towers is its unique ability to remove/eliminate mineral scale deposits from the towers without any additional acid washes or manual cleaning. Geist Unveils Rapid Deployment Data Center Environmental Monitoring System Geist has introduced a turnkey system that allows data center managers to deploy an environmental monitoring network within hours. Racknet–E (RacknetEnvironmental), the latest addition to Geist’s Racknet product line, combines data center management software and fully integrated environmental sensors to alert managers when heat or humidity levels threaten sensitive data center equipment. Racknet-E bundles can be fitted with wireless or wired sensors, each preprogrammed sensor reports temperature and/or humidity readings through the Racknet-E web accessible graphical user interface. The product’s easy-to-understand live views, userdefined calculations and historic trend reports provide the critical data necessary to eliminate potential problems related to the data center climate. “A quick response to environmental changes is crucial to protect servers and maintain uptime in the data center,” said Matt Lane, president of Geist DCiM. “Racknet-E gives managers access to a user-installed system with the real-time monitoring and alarms they need to head-off climate threats before they become catastrophic.” Racknet-E also has a full upgrade path to monitor other SNMP compatible devices located in the data center. After upgrading, users can elect to expand their monitoring capabilities to include power strips and other SNMP devices. Polyonics Announces New Flame Retardant Battery Tape for Bonding Applications Polyonics XT-657 flame retardant bonding tape helps prevent the propagation of fire, provides dielectric separation between electrical circuits and eliminates mechanical fasteners in battery assemblies and packs. The halogen free UL94 VTM-0 tested tape provides a thin, conformal bond line and offers an adhesive strength of greater than 32 oz/in (> 35N/100 mm). The tape has been proven effective in bonding Li-ion batteries used in space-constrained consumer electronics devices as well in industrial power and battery applications. XT-657 is a high temperature bonding system that is used to attach batteries and components to chassis, boards, other batteries, etc. The REACH and RoHS compliant tape includes a 1 mil (25 µm) polyimide film, two layers of 1 mil acrylic pressure sensitive adhesive (PSA) and a variety of liners that aid in handling, die cutting and auto application. The Polyonics bonding tape remains dimensionally stable at high temperatures, is resistant to the chemicals used in PCB manufacturing and designed to remain effective throughout wave solder and reflow processes. The tape also provides a high dielectric strength of >7.6 kV/mil (>299 kV/mm) that helps isolate electrical circuits and complies with the aerospace FAR 25.853 and BSS 7238/7239 smoke and toxicity standards. When a Li-ion battery is bonded to a PCB using the Polyonics XT-657 tape, the edges of the battery case are sealed using the Polyonics XT-708 flame retardant single coated matte black polyimide tape while the PCM circuit is isolated with the single coated Polyonics XT-624 flame retardant amber polyimide masking tape. ASR / SPR Series Handles Pulses Up To 10 KV Stackpole Electronics’ ASR / SPR series of anti-surge metal film resistors are designed to withstand high voltage pulses. Working voltage for the ASR and SPR ranges from 1,150 to 4,000 volts with overload voltage from 1,500 to 5,000 volts. In addition, the ASR / SPR can handle high voltage capacitor discharges from 3 KV for the smaller sizes up to 10 KV for the larger. The ASR and SPR series are a lower cost replacement for ceramic composition and carbon composition resistors where the pulse voltage capability of the resistor is critical or where the inherent inductance of wirewounds is undesirable. The ASR Series is available in resistance values from 10 ohm to 12 Mohm. The SPR series is UL 1676 rated and is available in values from 1 to 12 Mohm. Power ratings range from ¼ watt to 2 watts and 5 percent tolerance is standard. September/October 2013 www.ElectronicsProtectionMagazine.com 3 http://www.ElectronicsProtectionMagazine.com
