LOCUS is showcasing aluminum tube fittings and valves for air-conditioning and heating systems. They are made of an aluminum alloy with lead content less than 0.01%. The tube fittings and valves are installed using the threaded lock-type fitting connection method, with no welding required. The Taco Viridian is a Web-enabled, high-efficiency, wet rotor, variable-speed commercial pump. Its ECM motor saves up to 60% of electrical energy compared to conventional commercial pumps. Its multiple operating modes fit most applications. http://tinyurl.com/7joplzq Advanced Groove System (AGS) couplings from Victaulic are available for pipes ranging from 14 in. to 60 in. (356 mm to 1524 mm). The couplings feature two-piece housing segments, offering greater speed of assembly without welding. Its patented wedge-shaped groove can handle higher end loads and pressures of up to 350 psi. http://tinyurl.com/7mzz3cc COMPLETE SEAL fittings from Sheet Metal Connectors feature a double legged EPDM rubber gasket secured in place with a 180° hem. The gasket creates an airtight connection that eliminates the need to caulk. http://tinyurl.com/7xtcgft The EnviroFlo™ VIL series of vertical in-line pumps from Patterson Pump comes in split-coupled and close-coupled configurations. Flows to 10,000 gpm (631 L/s) with heads to 400 ft total dynamic head are offered. http://tinyurl.com/6uqc27p The New Dong Hae Company offers copper and stainless steel vibration absorbers for refrigeration and air conditioning systems. The vibration absorbers implement a piston stopper to provide a more positive seal and reduce leak rates. They are tested against hydrogen and helium leaks, and are rated to operate at temperatures from –40°C to 120°C (–40°F to 248°F). Air Test introduces a BACnet® communicating CO2 transmitter in its popular TR9294 wall-mount enclosure. This adds to the company’s capability to provide LonWorks® communication or dual analog outputs. The self-calibrating sensor requires no maintenance over its operating life. http://tinyurl.com/7rhfm3y Bell & Gossett, a Xylem Brand, offers System Syzer®, an HVAC tool that helps with system design. Version 4 employs major improvements in the Windows® program and is now available as a mobile application for the iPad® and iPhone® at iTunes® and the App Store. http://tinyurl.com/7alyn9y Standex Electronics features a full line-up of fluid sensing and power products for residential and commercial HVAC&R applications. http://tinyurl.com/7ykvqym The Data Industrial® 340 BN/MB Btu energy transmitter by Badger Meter is for submetering applications that use BACnet® or Modbus. It measures thermal energy by integrating the liquid flow rate in a closed-pipe system and the differential temperature between the supply and return. http://tinyurl.com/6rb3whc The Reliable Controls® MACH-ProZone™ is a fully programmable BACnet® advanced application controller (B-AAC) with scalable I/O in a small footprint. It is suitable for a range of
