(Right Photo) Nat Medlin (left) and James Heinz learn how to use a Big Dog Tools biter as a scroll saw. mum Energy is for buildings with VAV air-handling units. The product uses patented relational controls algorithms and can provide electrical and gas HVAC energy use savings of 25% to 40%. Fieldserver presented the FS-B35 Series FieldServer interoperability solution for building automation system integrators. The product offers four serial ports, two 10/100BaseT Ethernet ports, plus a LonWorks port, access to a large driver library and 1,000 point capacity. Schebler’s eVent series of prefabricated chimney systems come in odd and even diameters, from 5 in. (127 mm) to 48 in. (1219 mm), the largest in the industry. Larger diameters mean fewer stacks to vent multiple boilers, saving cost and space. Designed for government, military, medical, labs, and other critical facilities, Kathabar’s Secure Environmental System prevents the contamination of building ventilation air from outside sources. Grand Hall offers the Eternal Condensing Hybrid water heater. The product uses full-flow design and stainless steel heat exchanger with a built-in two gallon (7.5 L) reserve. The product can be wallmounted or floor standing with water connections on the unit’s top. American Hometec introduced its Model AHQ-C10 electric tankless water heater for low-flow multilavatory and single-use applications. The product

doesn’t use a coil. Instead, water is heated indirectly with a specially processed high-quality quartz tube heating technology. The WPS Series of water-cooled water chillers from Petra Engineering Indus-

More than 200 companies were firsttime exhibitors at AHR Expo. tries offer state-of-the-art low sound, reliability and high energy efficiency with a small footprint. The Bell & Gossett ecocirc potable water recirculator pump features ECM (electronically commutated motor) technology and a patented spherical motor design, eliminating the need for a conventional shaft, seal and bearing assembly. GrayWolf introduced a fully revised version of its environmental instrumentation operating software. WolfSense 2010, in conjunction with GrayWolf sensors,

transforms Windows XP/Vista/7 notebook PCs and Windows Mobile Pocket PCs into sophisticated air quality measurement instruments. The ModSync offers control and sequencing of up to 75 boilers. Features include a user-friendly touch screen interface that is easy to configure and navigate. Multiple screens provide key information for monitoring and configuring the loop parameters. Multistack’s Airstack ASP-30X features the addition of microchannel heat exchangers that reduce the refrigerant charge by 35% to 40%. A 20% air-side pressure drop helps create a 6% increase in energy efficiency. Metasys version 5.0 building management system from Johnson Controls includes Web-enabled reports and summaries compatible with the iPhone and iPod Touch platforms, and wireless controls and sensors. Ecô from Eagle Mountain is a browser-based energy management system that can be monitored and controlled remotely from any Internet connection, including handheld devices. It can interface with National Weather Service data to adjust setpoints in anticipation of weather changes, and provides system health updates and errors.
