Xylem Inc. - Experts & Thought Leaders

In pursuit of Xylem’s pledge to Building Better Futures and a focus on continuous improvement and excellence across all systems and solutions, Bell & Gossett’s redesigned Glycol Make-Up Unit GMU560 offers new enhancements. Ideal for use with automatically recharging glycol or glycol/water recirculating systems, this upgraded model is engineered with efficiency in mind. Critical system pressure levels The utilization of a 115V Flojet diaphragm pump helps maintain critical system pressure levels The utilization of a 115V Flojet diaphragm pump helps maintain critical system pressure levels to account for fluid losses that may occur due to leakage or evaporation, operating only as needed for optimal system control, and a hand-off-auto (HOA) control switch ensures total ease of use for regular operation and maintenance. What’s more, this pressurized solution for closed-loop heating, chilled water, process, radiant heat, or snowmelt systems is easy to install and completely automatic, offering operational and resource efficiencies. Xylem’s commitment "The enhanced Glycol Make-Up Unit GMU560 (GMU560S and GMU560P) represents another step forward in Xylem’s commitment to delivering premium packaged solutions to the market," said Jim Wilkinson, Product Manager, Packaged Systems, Xylem Inc. Jim Wilkinson adds, "With hydronic systems increasingly the more efficient choice for heating and cooling, being able to offer an updated GMU that meets this growing trend and includes the addition of a redesigned control panel, and also mechanical improvements is ideal for anyone seeking both user-friendly and eco-conscious solutions." Key features and benefits Key features and benefits of the enhanced Glycol Make-Up Unit: Requires a 115/1/60 single power connection and a 3/4″ MNPT system piping connection. Maintains minimum system pressure levels and provides protection from excess pressure through a pre-installed pressure relief valve. Incorporates low-level protection that automatically shuts down the pump when solution levels are low, activating check light and remote alarm contact. Eliminates leak paths between plumbing and tank, while the new design allows full access to piping from the front of the tank. Pressure-reducing valves and gauges allow for fast and easy system adjustments. Package available with PVC and steel plumbing. The improved model offers a significant net cost reduction compared to the previous design. Suited for use with glycol solution or potable water, the reservoir has a 55-gallon capacity.

Bell & Gossett’s Little Red Schoolhouse, the pioneer in industry education, is bringing its curriculum back to Canada with a two-day hydronics training seminar, to be offered in Toronto. Hosted by Michael Licastro, manager of training and education at Xylem–Bell & Gossett, the two-day Hydronic Training Seminar will take place June 5-6 from 8 to 4 p.m. at the Toronto Airport Marriott Hotel and reflects Bell & Gossett's larger Building Better Futures mission of preparing the next generation of industry professionals to design and maintain the sustainable building systems of the future. Two-day hydronic training seminar "With this offering, we acknowledge the importance of education in this region and the value of sharing our expertise with new professionals and building owners across Canada,” said Licastro. “70 years after the opening of the Little Red Schoolhouse, I’m thrilled to expand our reach across North America, providing a valuable opportunity to grow our program and connect with new individuals through our curriculum.” Attendees will receive a deep dive into the fundamentals of hydronic systems, covering topics The two-day hydronic training seminar is free of charge and will provide a comprehensive training program aimed at wholesalers and their contractors. Attendees will receive a deep dive into the fundamentals of hydronic systems, covering topics such as thermal comfort, pump selection, and system balancing. The training will include interactive sessions, case studies, and practical demonstrations. Parking will be $5 per day, and breakfast and lunch will be provided. Seminar Agenda Wholesaler Day 1 Introduction with discussion on using hydronic systems to provide thermal comfort, including an overview of combustion and non-combustion heat sources Fundamentals and rules of thumb: Determining required flow rates, pipe sizing, and system friction losses Determining total pump head and hydronic proportional balancing strategies Pump and system performance curves: What are they and how to use them for final pump selection Wholesaler Day 2 Closed loop hydronic system air management and pressurization Wholesaler Day 2 Closed loop hydronic system air management and pressurization Includes example on how to size an expansion tank Zoning a hydronic system using valves or pumps Application of primary-secondary pumping Designing a series loop for a residential application future training opportunities Limited to 60 students, registration for the two-day hydronic training seminar is now open, and interested individuals can secure their spot by visiting the registration website. If class capacity is reached, a waitlist will be created for future training opportunities.  In addition to the Toronto training seminar, the Little Red Schoolhouse offers in-person classroom training at its Morton Grove, Illinois, schoolhouse and traveling classes across North America, free online learning opportunities through an upgraded online portal, and downloadable training manuals.

McDonnell & Miller, a Xylem brand, is proud to introduce updates to its electronic Low Water Cut-Off (LWCO) product line, including the GuardDog® RB-24SE Low Water Cut-Off and RB-122E Low Water Cut-Off for Hot WaterBoilers.  Arriving during McDonnell & Miller’s centennial, these product line enhancements signify the company’s legacy as an industry pioneer committed to reliable engineering and manufacturing and continuous innovation. Common features The GuardDog® RB-24SE and RB-122E share a variety of features, including an exclusive, patented McDonnell & Miller self-cleaning probe, the only low water cut-off equipped with one. Saving time and money, the self-cleaning probe minimizes scale build-up and protects users from potential boiler shutdowns or water overfill, while extending the recommended cleaning interval. The updated LWCO line also features a leak-free metal-to-metal seal and a push-to-test button The updated LWCO line also features a leak-free metal-to-metal seal and a push-to-test button that quickly confirms proper operation, enabling low water cut-off protection to be verified without draining any part of the system. efficient and reliable solutions  “Upgrading the LWCO line positions Xylem to further meet growing industry demands and reflects McDonnell & Miller’s 100-year-old commitment to engineering efficient and reliable solutions that strengthen user experience and simplify operations,” said Jarek Berezowski, Product Manager, Steam Specialties, Xylem Inc.
