The new Bell & Gossett e-HSC pump boasts an advanced seal chamber design. This paper outlines the benefits in reduced downtime this technology provides in water applications.
The newly designed Bell & Gossett e-HSC pump standardized on a stainless steel shaft and impeller. This paper outlines the benefits of stainless steel in performance and product life.
Hydronic systems outperform VRF, analysis finds. Upfront costs and energy consumption are primary drivers when selecting a commercial HVAC system in new and retrofit projects. A new study commissioned by Xylem underscores the importance of evaluating total life-cycle cost in the selection process to adequately identify pros and cons of the various system types.
Best efficiency staging achieved with technologically advanced controllers and variable speed drives. Vince Lombardi’s Green Bay Packers were famous for their power sweep, and ran the play over and over again with great success. When opposing teams began making adjustments to stop the sweep, Packers quarterback Bart Starr read the defense at the line of scrimmage and could alter the play to ensure the best outcome.
DOE energy rating includes constant load and variable load equipment. Beginning Jan. 27, 2020, clean water pumps sold in the United States must achieve a minimum energy rating of 1.0 as outlined in the Energy Conservation Standards for Pumps established by the U.S. Department of Energy (DOE) and adopted by Natural Resources Canada. Even though that number denotes compliance with the new standards, a compliant pump by itself is not a measure of an efficient hydronic HVAC system.
With heating and cooling among the largest costs in commercial buildings, HVAC system selection is an important component in both new construction and retro t projects to keep costs in line and realize energy-efficiency targets. Hydronic systems provide water-based heating and cooling, a proven, cost-effective and sustainable medium.
This paper explains the importance of using B&G’s Part Load Efficiency Value (PLEV) calculation when selecting centrifugal pumps for hydronic systems.
This paper explores the operational performance and efficiency differences between variable refrigerant flow (VRF) HVAC systems and geothermal/hydronic pumping HVAC systems.
White Paper Series: Part 1 – How to read a pump performance curve Presented by: Xylem Applied Water Systems Understanding how to read a pump curve is critical in selecting the right pump for an HVAC or water system in a commercial building. Selecting the right centrifugal pump for the facility will, in turn, maximize pump
Pump cavitation and how to avoid it Best practices in pump system design Presented by: Xylem Applied Water Systems Cavitation is not a new phenomenon that can impact a pump system, but it is an issue that is growing. While no official figures exist, it is not misleading to say that in the last five
As the complexity of building systems continues to increase, the challenge of designing, installing and operating these systems also increases. New building codes continue to raise efficiency standards for new and existing buildings; economic conditions pressure organizations to cut energy costs wherever possible; and new corporate sustainability initiatives require steady efficiency improvements.
Presented by: Xylem Applied Water Systems Pumps that perform at a best efficiency point are becoming a thing of the past. Why operate at a single point when you can experience optimal efficiency across an entire island? This white paper introduces the concept of Efficiency Island and reveals how pump efficiency in HVAC systems can
