The following residential and commercial products keep systems running smoothly, while boasting user-and maintenance-friendly features. 1 2 1. DUAL PROTECTION WITH DIRTMAG PRO Caleffi North America introduces the DirtMag Pro, for use in residential and commercial hydronic systems. The patented technology includes dual magnetic fields, increasing ferrous oxide impurity removal efficiency by 40%. A particle separation mesh also captures non-ferrous dirt, such as copper shavings, pipe tape and solder balls that can wreak havoc on sensi-tive system components. All of these impurities are easily and quickly purged from the system using a simple blow-down valve, while servicing expediently as no disassembly or scraping magnetite from wetted magnets is required.

BOILER BOASTS WHISPER QUIET OPERATION, BUILT-IN ZONE CONTROL The 95% AFUE ECO Tec boiler from Weil-McLain is available in both heat only and combi versions and satisfies all residential space and domestic hot water heating needs. It features a durable stainless steel fire tube heat exchanger with sound-dampening air silencer for whisper quiet operation, and a corrosion-resistant condensate collector base. The unit also includes built-in zone control, connects to four thermostat inputs and features easy-to-use setup wizards and heating system presets. ECO Tec is easy to maintain and service with a spacious cabinet that allows full access to internal components and features a user-friendly touch-screen display. CHECK OR CIRCLE #107 3. AIR & SEDIMENT SEPARATOR LINE REMOVES IMPURITIES Bell & Gossett, a Xylem brand, has expanded its CRS Coalescing-Style Air & Sediment Separator product line. The extended CRS line 3 helps break entrained air and suspended solids out of system fluid, efficiently removing these contaminants and improving heat transfer and energy efficiency. With lower-energy use and its robust design, the CRS helps protect pumps, boilers and other components, improving and prolonging the life of a system. The CRS separator’s internal coalescing media efficiently removes up to 100% of fluid contaminants, improving heat transfer capabilities and resulting in energy efficiencies.

TACO COMFORT SOLUTIONS INTRODUCES HIGH-EFFICIENCY CIRCULATORS Taco’s new VR Series high-efficiency ECM cast iron or stainless steel circulators offer a wide range of low-, medium-or high-head options in sizes from 1/3 to 2 horsepower. Intuitive settings and operation will appeal to installers for a broad range of uses, including HVAC, hot water recirculation and NSF commercial hot applications. 00e VR circulators provide an easy-to-program pump interface with real-time feedback. Modbus, BACnet, 0-10Vdc + pulse width modulation come standard. The circulators provide 62 feet max head and up to 320 gpm flow. They are NSF/ANSI 61 + 372 commercial hot certified. CHECK OR CIRCLE #109 5. HYDRAULIC SEPARATOR UPDATED WITH MAGNETS FOR IMPROVED EFFICIENCY Spirotherm has improved its Quad hydraulic separator by adding powerful magnets. The Spirovent Quad with magnets delivers the same air separation efficiency and adds fast and effective separation of ferrous and non-ferrous debris, while providing the critical interconnection between hydronics loops. Powerful magnets located on the exterior of the housing surround the flowpath of the system water to efficiently capture ferrous material. By sliding the magnet jacket down, the collected debris can be flushed from the unit without having to isolate or open the unit. The updated Spirovent Quad is available in 1, 1-¼ and 1-½ inches with threaded, sweat and press fit connections. It is backed by a 20-year limited warranty.
