Brazed Plate Tops Talk By Peter Powell Of The NEWS Staff GOODWAY COIL CLEANERS Save Heating/Cooling Dollars and Improve Indoor Air Quality Dirty HVAC coils cost you money. Clean coils are more efficient and reduce the amount of energy needed to heat or cool your building, saving you money. Goodway offers several Coil Cleaners with either a penetrating foam spray and gentle water flush, or a powerful vacuum to safely remove deposits. CC-100 EW YORK — “Brazed plate” was the catchphrase in the heat exchanger sector at the 2008 Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo). Companies were showing a range of exchanger technologies, but brazed plate proved to be the most frequently seen and most highly touted by their advocates. Danfoss (www.danfoss.com/ north_america) introduced brazedplate heat exchangers consisting of a series of thin, corrugated metal plates brazed together to improve heat transfer efficiency. “We are continuously striving to develop and provide environmentally friendly and energy-efficient products,” said Peter D’Ambrosio, strategic global marketing manager-heat transfer. “Our brazed-plate heat exchangers are space saving, offer a highly flexible design for manufacturing, and require less use of refrigerants.” The company said it is offering 15 models. N (www.camlee.com). It comes in a wide range of product sizes to serve a variety of applications. Delphi (www.delphi.com) showcased microchannel heat exchangers. Delphi Thermal Systems features brazed product and process technologies. A variety of heat exchangers was shown by AIC Advanced Industrial Components (www. myaic.net). The lines include plate-and-frame, vertical HE, and brazed-plate models. Brazed-plate heat exchangers and plate-and-shell heat exchangers were on display by Sondex (www.sondex.dk). For the former, the company noted its products can “operate continuously at temperatures from -180˚ to 200˚C.” The latter types have plates welded together to form a plate pack that is mounted inside a traditional cylinder shell. Plate-and-frame heat exchangers were shown by Plate Concepts (www.plateconcepts. com). The company’s contention was that “the plate-and-frame heat exchanger is widely consid- coefficients, the company said. The turbulence, uniform fluid flow, and smooth plate surface help reduce fouling and the need for frequent cleaning, the company said. COILS An extensive range of coils was displayed by Luvata (www. luvata.com/heatcraft). The company also used the expo to note Goodway Coil that it emerged when Outocleaners are ideal for: kumpu Copper Products was • Heating acquired by Nordic Capital. The Coils line of custom-made coils covers • AC Coils fluid coils, direct expansion coils, • Convectors • Evaporators desaturation coils, heat reclaim • Condensers coils, and tube bundles. • PTAC Units Replacement coils, duct heating coils, and heavy-duty industrial coils were shown by Coil Company (www.coilcompany.com). ■ Goodway041607.indd 1 CVC-100 CC-140 Call Us With Your Dirt 800-333-7467 ® Innovative Maintenance Solutions www.goodway.com eProduct #23 at achrnews.com 3/2/07 11:03:52 Using UVC in HVAC systems: Good ■ practice. Join the thousands who are using UVC to: KILL recirculating viruses and bacteria as well as mold deep inside the system for enhanced mold, IAQ and infection control. SAVE 15% or more on energy costs by keeping A/C coils free of mold and buildup… reduce or eliminate coil cleaning. REDUCE liability worries associated with building-related illness and sick building syndrome. ™ Companies were showing a range of exchanger technologies, but brazed plate proved to be the most frequently seen and most highly touted by their advocates. Plate heat exchanger technology from Alfa Laval Inc. (www. alfalaval.com) showed high capacity technology designed to “allow customers to use one heat exchanger with the potential to expand within length of frame to meet new (efficiency) requirements.” The company also said the plate is optimized for close temperature approach conditions, for maximum energy efficiency in HVAC systems. The company said a key feature was connections, with flow rates up to 8,000 gpm. Applications include free cooling, pressure interceptors, and building interchangers. The company also presented a seminar, “Heat Exchangers in CO2 Cascade Systems,” at the New Product Technology Theater on the show floor. GEA PHE Systems of North America (www.geaphena.com) showed brazed, gasketed, semiwelded, and fully welded plate heat exchangers. An inner-grooved tube for use with heat exchangers and air conditioning and refrigeration equipment was featured by Cambridge-Lee Industries LLC ONLINE AT WWW.ACHRNEWS.COM ■ ■ ■ Using Steril-Aire UVC Emitters : Don’t just settle for any UVC device, get the best: Steril-Aire! ■ Best practice! ered the most efficient type of heat transfer equipment available today. PFHX are often the lowest cost solution to heat transfer problems in the industrial and commercial HVAC market.” Zhijiang Zhuji Dunan Heat Exchanger Co. (www.www.china dunan.com) discussed heat exchangers for central a/c, computer room a/c, transportation, and refrigeration systems. Cesaroni Technology Inc. (www.cesaronitech.com) showed all-polymeric heat exchangers. The company said its PolyCoil heat transfer systems have been developed for applications ranging from military vehicles and small pleasure crafts to HVAC equipment, thermal ice storage systems, and evaporative fluid coolers. New Accu-Therm plate heat exchangers from Paul Mueller Co. (www.muel.com) are designed to provide efficient heat transfer whether processing simple fluids, viscous solutions, or particulates, the company said. The embossed pattern was designed to promote high turbulence at low fluid velocities, resulting in high heat transfer BEST ACCEPTANCE: Backed by over a dozen patents, 10 industry awards and top rankings in brand preference studies. BEST OUTPUT: 5 times higher UVC output verified by independent testing, for the longest life and best germicidal performance. BEST PRODUCT LINE: Sizes and configurations to fit virtually any new or retrofit need. BEST QUALITY: All products manufactured in an ISO 9001:2000 facility. Electrical Cost ($) ■ ■ ■ JAN FEB MAR APR MAY ENERGY DATA: Rio Grande Regional Hospital reports dramatic HVAC energy savings since installing Steril-Aire lights. From 1/07 – 5/07, electrical costs dropped $240,885 or 29.5% vs. the same period in 2006. Based on this trend, savings of $500,000+/per yr. are projected.
