FOCUS By Cherie R. Preville and John R. Hall Of The NEWS Staff AHR EXPO POST-SHOW ISSUE Hydronic Products Make a Big Splash EW YORK — The new products in the hydronics area added up to more than you can shake a stick at, at the 2008 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo). There were a range of product types and companies that offered this equipment, as well. Aurora (www.aurorapump. com) introduced its 3310 Series of pumps, which are designed to conserve floor space and reduce installation costs. The close-coupled footprint of the pumps can reduce required floor space by 40 percent when used in a horizontal position or 60 percent when used in a vertical position. Installation costs are reduced by minimizing the need for piping supports. In addition, the 380 Series of inline pumps has a split-couple (SC) option that makes the pump easier to service in the field. “It takes service from a two-person job to a one-person job,” said Steve Ecuyer, Aurora national sales manager. Bell & Gossett (www.bell gossett.com) introduced its next generation of ZoneTrol II zone controllers with optional outdoor reset control. The ready-to-install controller can be used in both residential and light commercial applications. Features include a microprocessor design that doesn’t need add-on circuit boards or modules. All 10 models are compatible with analog and digital 24-vac thermostats. Four- and six-zone controllers are field expandable for up to 18 pumps and are available with integrated, prewired boiler reset or mix reset controllers. Burnham (www.burnham. com) introduced the MPC™ cast iron commercial boiler. The Sage Boiler Control™ (SBC) boiler monitoring system provides boiler modification, operating control, diagnostics, multiple boiler leadlag, and auxiliary device control. It has a combustion efficiency of 89 percent for oil and 86.3 percent for gas. A display provides readouts for all system functions, including supply, return, temperatures, modulation rate, and boiler sequence. The Beckett burner has a 0.85gph firing rate and a 1 ½-inch steel coil double-wall heat exchanger. Other features include ¾-inch water connections, thermostatic mixing valve, and a maximum heating capacity of 55,000 Btuh. Cleaver-Brooks (www.cleaverbrooks.com) introduced an addi- N Steve Ecuyer, Aurora national sales manager, points out the special split-couple option on Aurora’s 380 Series of inline pumps. Robert Riccio, Cleaver-Brooks regional vice president, shows off his company’s Premier Commercial Boiler Line: the Clearfire Model CFV-Steam. Sheldon Schiffner, Wilo vice president of sales and marketing, stands next to the Wilo IL Dry Rotor Inline Centrifugal Circulator. Weil-McLain introduced a new jacketing design on the 88 Series 2, which has 3 inches of insulation to improve thermal efficiencies. tion to its Premier Commercial Boiler line, the Clearfire Model CFV-Steam. The company called the Clearfire-V “the new standard in commercial high-efficiency firetube boilers.” Features include full modulation with high turndown via variable-speed blower, low emissions (under 30 ppm NOx and under 10 ppm CO), high efficiency with greenhouse gas reduction, and low-noise operation. “This new boiler puts us in a market we haven’t been in,” said Robert Riccio, Cleaver-Brooks regional vice president. “We are very excited about this new technology.” Another new item the com- pany brought to the expo was the Falcon ISD Intelligent Sequencing Device. It is designed for use with the line of Clearfire CFC full-condensing hot-water boilers, but can also be used to sequence and con■ 12 AIR CONDITIONING, HEATING & REFRIGERATION NEWS February 18, 2008
