Bell & Gossett Highlights Leadership in Efficiency at 2017 AHR Expo


Bell & Gossett (B&G), a Xylem brand, will showcase its industry-leading line of energy-efficient pumps and technologically advanced drives during the 2017 International Air-Conditioning, Heating, Refrigerating Exposition (AHR) Jan. 30 through Feb. 1 in Las Vegas. Key highlights include B&G's DOE-compliant pumps, its new pump selection criteria called Part Load Efficiency Value (PLEV), and a new Online Little Red Schoolhouse course on modern pump selection.

DOE compliance

B&G’s e-Series pumps meet and exceed efficiency benchmarks set forth by the U.S. Department of Energy (DOE) in its new standards for centrifugal pumps, three years before the 2020 compliance date. B&G’s product portfolio for commercial building services applications has the largest Efficiency Islands compared to similar pumps, ensuring systems maintain significantly higher levels of efficiency over a wider range of operating conditions.

“Xylem is the only U.S. manufacturer that currently offers a complete product line that meets the new standards, which benefits our customers who are seeking total system solutions,” said Mark Handzel, Vice President Product Regulatory Affairs and Director, HVAC Commercial Buildings, Americas, Xylem. “These highly efficient pumps not only use less energy — one of the primary goals of the DOE regulations — they also contribute to increased system performance and lower life-cycle costs.”

Introducing PLEV

B&G’s PLEV is a new tool for HVAC system designers to specify the most accurate and efficient centrifugal pumps based on their true performance within a hydronic system. PLEV, which stands for Part Load Efficiency Value, is a calculation based on the partial load that a pump will experience most of the time it’s in operation in a commercial building HVAC system.

“HVAC system designers look for smarter ways to maximize efficiencies while reducing costs,” Handzel said. “By matching the equipment more precisely to actual system demands, pumps will use less power and require less maintenance, extending equipment life and meeting efficiency standards.”

B&G will preview a new Online Little Red Schoolhouse course about modern pump selection in the booth. During the five-module course, students will learn best practices for selecting pumps for hydronic systems based on their true performance, taking into consideration PLEV, the pump performance curve, duty point and the effects of oversizing.

As with all Online Little Red Schoolhouse courses, the new course is free to engineers, designers, contractors, building operators and students, and qualifies for continuing education credits. The complete Online Little Red Schoolhouse curriculum covers centrifugal pump and piping system basics, waterside economization, pressure boosting systems and other trending industry topics.

The Online Little Red Schoolhouse is a complement to the hands-on training that more than 61,000 engineers, contractors and installers have experienced since 1954 at the B&G Little Red Schoolhouse in Morton Grove, Illinois. There, HVAC professionals learn the proper design, installation and maintenance of hydronic systems, as well as the latest technologies and regulations that affect the industry.
