CaseInPoint Anyone can claim to save you a lot. Fume collection units were installed at this casino/resort to eliminate food odors that were emanating into guest rooms. odors and electrically charge contaminants, which are then captured onto aluminum collection plates. Smog-Hogs do not require costly ﬁlter replacements. Instead, units are programmed to shut down for one hour each day for selfcleaning. UAS tailored this maintenance schedule according to staff downtime. This continuous cycle allows them to serve guests night and day. Additionally, the Smog Hogs use the existing supply of hot water, saving the resort and casino the costs of sourcing and heating additional resources. The Smog Hogs at Sandia Resort & Casino were designed to ﬁt the resort’s unique space and architectural requirements. Each unit was split into multiple parts to accommodate the resort’s roof load speciﬁcations and placed in locations that made them easily accessible for routine servicing. The units were also painted to blend into the buildings unique southwest façade. Above all, UAS worked with Sandia Resort & Casino to make sure every step of the planning and implementation process went smoothly. In addition to their engineering house, UAS was an integral part of the layout, installation drawings, contractor meetings and startup service — including ﬁnding the largest crane in New Mexico to lift the rooftop units into place. After installation, UAS continued follow up with general startup assistance and application engineering advice. IMPACT Mark Cuzzola, facilities manager for Sandia Resort & Casino reported the results. “While our original exhaust fans were working to some extent, they weren’t nearly as effective as the Smog-Hogs are. These new units allow our HVAC team to concentrate on other areas, as wash cycles and operations are all computerized. The HVAC staff only needs to perform routine maintenance and exchange cleaning solution once a month. These units have shown to be low maintenance and have already provided savings in labor costs compared to the old exhaust fans. The additional savings have been in these units not requiring monthly ﬁlter changes.” “We looked at the required investment in UAS equipment and decided it was deﬁnitely worth it, considering the long-term savings,” said Paul Collins, superintendent of facilities for Sandia Resort & Casino. “The initial upfront cost was never the concern. The Council wanted results. The results, to date, have been exceptional. Since installing these UAS units, there have been zero complaints from guests regarding food odor or any type of aroma from the kitchens. The UAS systems clean all the exhaust, and only fresh clean air is exhausted.” “Not only was the UAS team very attentive and great to work with, they helped us come up with a tailored solution that does exactly what we need it to.” AERCO. Condensing design with unmatched turndown. Benchmark Boilers. Condensing is just part of the savings. Even before an independent third party confirmed the full- and part-load efficiency of our BMK2.0LN, we knew our unmatched 20:1 and 15:1 turndown would virtually eliminate cycling losses, minimize wear and tear, and improve temperature control. And with no need for primary pumps, three-way valves or extra heat exchangers, Benchmark boilers streamline system designs and reduce maintenance requirements. Plus, our flexible venting and air intake options also help lower project costs. To learn more visit www.aerco.com/bm4 Heat You Can Bank On Copyright 2008 AERCO International, Inc.
