When used in conjunction with the VAF Turbulator Eductor nozzle system, a wide stream system can provide an efficient method for keeping tower basins clean without interrupting the facilities processes. The LCF-Series significantly reduces maintenance costs, energy costs, chemical usage, and water consumption.
Van Packer Co. displayed its Model GZ two-hour, fire-rated, zero-clearance grease duct, available in sizes ranging from 6- to 10-inch inside diameter in 1-inch increments and 10- to 36-inch sizes inside diameter in 2-inch increments.
Vesbo North America Inc. showcased its composite faser pipe made of polypropylene random co-polymer (PP-R) resins. It consists of three layers, with 20 percent glass fiber/PP-R sandwiched between PP-R material in the inner layer and the surface layer. Vesbo EVERgreen pipe is designed for potable water, hot water, chilled water, and process water. Terra Verde pipe is designed for hot water, chilled water, and process water applications. Violetta pipe is designed for use in reclaimed water systems, which can be used for industrial cooling.
Victaulic Co. highlighted its Style 107 QuickVic® rigid couplings in 10- and 12-inch sizes, which expedite project construction by reducing installation steps, requiring only standard hand tools for assembly. Installation-ready technology features no loose parts and no need to disassemble before installation; the coupling is simply pushed onto the pipe-end as a fully assembled unit, joined by a second pipe-end and tightened. The company
also highlighted its Series TCP Pressure Independent Balancing and Control Valve (PIBCV), featuring balancing and control valve functions that are separate with full-stroke EQM modulation, providing superior control valve authority regardless of preset position. Both functions are optimized, providing building owners and designers the ability to optimize energy savings through optimal flow control.
Virginia, a Parker-Hannifin Corp. brand, introduced a patent-pending, high-foaming outdoor coil cleaner that penetrates deep into air-cooled condenser coil fins to remove dirt, cottonwood seeds, leaves, grass, and corrosion. The expanding foam pushes contamination out of the coil and is rinsed away with water. QWIK-Brite contains two acids, excluding hydrofluoric acid. The biodegradable, environmentally friendly formula breaks down naturally and does not contaminate groundwater.
Wessels Tank Co. showcased its WesPlate® heat exchanger, which consists of stamped plates designed to maximize heat transfer. Gaskets are fixed between the plates to contain the two separate fluids, which flow alternately between every other plate in order to produce the greatest rate of heat transfer and provide the closest temperature approach to the incoming cold fluid. The stamped plates use enhanced surface area to create scrubbing turbulence that increases the U-coefficient and increases heat transfer.
Westermeyer Industries Inc. has expanded its product offering with a full line of code-approved high-pressure components supporting operating pressures of transcritical CO2 systems. Transcritical components include oil separators, oil reservoirs, accumulators, and receivers. All of the products are designed to handle pressures up to 1,885 psig.
Western Enterprises, a Scott Fetzer Co., featured its HVAC nitrogen-purging hybrid regulator. It combines a nitrogen regulator and flowmeter, allowing the user to purge, braze, and pressure test with one unit. All settings are preset (purge, braze, test). No tools are needed to install it on a nitrogen cylinder. Two models are available: 250-psi test pressure (VN-250) and 500-psi test pressure (VN-500). The company said the product helps to ensure consistent high-quality installations while eliminating return service calls.
Wintech Windows showcased its Stainless Steel HVAC Access Doors. The all-stainless steel doors are designed for food-grade and petroleum applications for custom and OEM air-handling equipment. Panel thicknesses are available in 1 ½- or 2-inch sizes. Options include standard or Food and Drug Administration (FDA) gaskets, and are available in 304 or 316L stainless steel skins. Doors are insulated with BASF Autofroth® Free Rise Foam. Air leakage is tested at less than 0.1 cfm at 15 inches wc. Water leakage was measured at 0 percent at 4 inches of wc.
WSA Engineered Systems highlighted its brush-type automatic tube cleaning technology, which helps permanently solve the problem of fouling and deposits in heat exchangers, chillers, and condensers. The system wipes off foulants to maintain condenser performance and heat exchange rate using only four components without restricting water flow.
Xylem Inc. introduced the Series e-1510 single-stage end-suction centrifugal pump, which addresses key applications in commercial HVAC and plumbing systems. It offers a variety of configuration options, is available in 26 sizes, and offers flow rates of up to 4,000 gallons per minute (gpm). Also featured was the ecocirc XL high-efficiency large wet rotor circulator pump with smart communications capabilities and an ECM motor that enables pump operations to match demand. Designed for commercial heating and cooling systems, hot water applications, solar-thermal systems, and ground-source heat pumps, the ecocirc XL features automatic night setback, control options, and an optional Wi-Fi module.
Yaskawa America Inc. debuted the Z1000 variable-speed drive designed for building automation applications such as fans, pumps, and cooling towers through 500 hp. The Z1000 features HVAC-specific application macros, an LCD keypad that provides hand-off-auto interface, and a real-time clock.
Z-Flex U.S. Inc. showed its polypropylene flue systems for boilers and water systems.
ZoneFirst introduced its Plug-In Damper Motor with Adjustable Minimum Position. Previously, the motor was available only as full open and closed. Now the motor can be set to a minimum position to allow a constant minimum airflow through the damper instead of closing the damper fully. This can aid in reducing air noise and serve to bypass excess air in lieu of a using a separate bypass duct. A simple flip-down door accesses the movable cam, which is easily adjusted to set the minimum position. A small screw holds the cam in place when tightened. This adjustable feature includes simple plug-in wiring and an included modular cord. A visible two-color LED indicates the damper position and makes the MP12M the simplest motor to wire and checkout. All of the company’s Plug-In Dampers are now shipping with this new feature.
ZSI Inc. displayed its Cush-A-Nator, which is manufactured in the U.S. and made from a new, durable thermoplastic rubber that resists high heat and provides longer life against vibration fatigue. The Cush-A-Nator is made from a proprietary thermoplastic vulcanized material cross-linked with high-performance rubber and thermoplastic elastomers, which produces the highest operating temperature range in the industry.
