Consulting-Specifying Engineer - December 2007 - (Page 52) in sizes of 0.25 in. and 0.5 in. and the filter particulate ratings are 5 to 40 microns. (Parker Prep-Air Stainless Steel Series by Parker Hannifin) www.parker.com/ pneumatics #3 (2x2 Diffusers by Metal Fab) www.metal-fabinc.com #4 AC Network devices Diffusers feature a cone design for maximum airflow. The diffusers are available in 2-cone, 3-cone, and perforated models. The collar design features a 2.25 in. collar for flex duct connection. The device also features a preformed insulation shell and is made of heavy gauge steel with no sharp surface edges. The diameter of the collar comes in sizes of 6 in., 8 in., 10 in., and 12 in. H provide accurate timestamping and synchronization across all power system components. The device synchronizes equipment clocks using network time protocol. The timeserver offers coordinated universal time by communicating through traditional global positioning system and code division multiple access cellular broadcast signals thus maintaining an accuracy of 100 nanoseconds. The device is capable of obtaining 100,000 data samples per cycle and coordinated throughout the power Voltage power packs system to within one millisecond. (Power Xpert Network Time Servers by Eaton) www.eaton.com #5 C Wireless networking tools resolves interference issues and features high levels of frequency resolution, amplitude resolution, and amplitude range. The technical specifications include an external antenna; a frequency range of 2,400 MHz to 2,495 MHz; a frequency resolution of 328 KHz; an amplitude range of -110 dBm to -6.5 dBm; amplitude resolution of 0.5 dBm; a sweep time of 165 ms; and is USB 1.1/2.0 compatible. (Wi-Spy 2.4x by MetaGeek) www.MetaGeek.net #6 A L Voltage power packs supply power for as many as four sensors.The device features a manual on/off control and automatically detects input line voltage from 100 VAC to 277 VAC, which eliminates the need for voltagespecific or multi-voltage power packs. The device is capable of switching 20amp loads and features zero arc point switching technology that minimizes relay contact wear associated with high inrush loads. (Universal Voltage Power Packs by Hubbell Building Automation Inc.) www.hubbellautomation.com #8 H Commercial boiler supports dual-fuel, natural gas, and propane applications. The boiler features a 3 million Btuh condensing power, a 15:1 turndown over an operating range of 200,000 to 3 million Btuh, and matches fluctuating loads to minimize boiler cycling and eliminate temperature overshoot. The boiler also achieves 99.4% efficiency at its lowest firing rate. (BMK 3.0LN by AERCO Int. Inc.) www.aerco.com #9 Linear fluorescent high-bay lighting L addresses elevated temperature through advanced thermal management. The lighting system provides an approach that dissipates and controls heat-producing elements. The lighting system features an aluminum ballast and heat distribution slots that remove ballast heat from the channel and reflectors.
