Download PDF Chief among these safety features is fire protection. There are myriad codes and regulations relating to fire safety in commercial buildings, from standards on portable fire extinguishers to the installation of stationary pumps for fire protection — the U.S.- based National Fire Protection Agency (NFPA) alone has more than 300 consensus codes that

Streamlined BIB platforms also provide reliability and performance Presented by: Xylem Applied Water Systems Download PDF At a time when fountain installers and bottlers are asking their distributor partners in beverage dispense for the ideal pump for standard bag-in-box (BIB) applications; and restaurant, bar, gas station and convenience store owners and operators are seeking more
Presented by: Xylem Applied Water Systems Download PDF Energy and maintenance expenses account for approximately 75 percent of the life-cycle costs of a centrifugal pump. With a growing emphasis on reducing energy consumption driven by government regulation and businesses seeking operational and financial efficiencies, HVAC system designers are seeking system solutions that maximize efficiencies while
Presented by: Xylem Applied Water Systems download PDF Now that the head capacity relationship along the X and Y axes of the pump curve has been established in Part 1 of this series, the pump curve can be used to determine the amount of horsepower required to meet the head and capacity requirements for the
Hydronic systems: Technologically advanced and highly efficient In head-to-head comparisons, hydronics outperform VRF systems »
This paper explores the operational performance and efficiency differences between variable refrigerant flow (VRF) HVAC systems and geothermal/hydronic pumping HVAC systems. download PDF Presented by: Xylem Applied Water Every minute of every day, valuable data is collected about energy consumption at the American Society of Heating, Refrigeration and Air Conditioning Engineers headquarters in Atlanta.
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
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.
One of the advantages of the new Aquavar Intelligent Pump Controller (IPC) is the flexibility to use the drive in many different applications. Whether it is a borehole application requiring outdoor enclosure or surface mount pump and motor requiring a drive to withstand corrosive environment, the IPC has the right solution. Each drive enclosure is constructed to provide a different degree of protection to personnel against access to hazardous parts. The following table is meant to serve as a quick reference tool to easily compare and contrast different types of enclosures as well as to provide some general applications to help specify selection.
