FRS 660 fuel recirculating systems remove contaminants from fuel and keep it fresh. The six FRS models in the 660 series are designed as integrated units, consisting of a pump, pump motor, programmable controls and accessories. Each unit is pre-wired, pre-plumbed and factory-assembled for virtual turnkey installation. All models are designed for use with fuel oil (Class II or Class III combustible liquids having a flash point of 100°F or higher).

High-speed wireless network connects campus building with remote data center
To help with campus growth and limited space, some schools move non-academic operations and personnel off-campus. This can create a challenge for telecommunications. At most schools, fiber-optic lines come into a single point, with a “fiber ring” local-area network connecting buildings on campus. Installing fiber lines to link remote off-campus buildings is expensive and time-consuming.
Dartmouth College, Hanover, N.H., has one of the most advanced university IT infrastructures in the nation. The college became concerned about finding a reliable network technology that would connect its telecom building on campus with the college's data center a mile and a half away, and provide sufficient bandwidth at the same time.
Dartmouth chose WiFiber wireless fiber technology, which is a point-to-point wireless network that operates at high radio frequency to transmit at speeds of a gigabit per second — equivalent to 1,000 DSL connections. With WiFiber's speed, which uses Gigabit Ethernet protocols, 90 minutes of video can be downloaded in about 6 seconds.
WiFiber works with two small antennae, positioned within the same line of sight, which emit thin pencil beams less than a degree wide. Because the beams can go through glass, the antennae can be placed on a roof or inside a building. At Dartmouth, one end of the communications link is inside a building, behind a window. The wireless network, which offers the same quality and reliability as fiber-optic lines, sets up in about a day at a tenth of the cost of fiber.
The university also is looking at other applications of WiFiber, such as deploying the wireless technology as an alternative backup network.

As good as new
Roof restoration saves school district 85 cents on the dollar
In January 1983, a ballasted EPDM roof system was installed on Hawthorne Elementary School, Vernon Hills, Ill., under the eye of a full-time roof consultant. Twenty-one years later, that same roof consultant inspected the roof to determine its condition and recommend replacement if required.
The roof inspection revealed that a number of building elements such as skylights and HVAC equipment were beginning to deteriorate. The 45 mil EPDM membrane appeared to be in great condition, and a sample was taken for testing.
Test results confirmed that the EPDM on the roof had material characteristics that exceed the minimum requirement of membrane manufactured today. The adhesive lap seams were tight, with no known deficiencies. Some bridging at the vertical wall base flashing was observed. The recommendation was to restore the roof with the goal of achieving at least another 10 years of service life.
The restoration design involved replacing the skylights with ones that meet OSHA fall-protection guidelines; redesigning and improving the HVAC intersection with the roof; the installation of semi-cured, self-adhering EPDM cover strips over all lap seams; the installation of target patches at the roof drains; the reflashing of all roof curbs and base flashing conditions; and installing a new cover strip at the gravel stop.
The total restoration cost was $52,000, including the replacement of 10 skylights. Removal of the existing roof system and installation of a new roof system was estimated at $450,000.

Gauging power usage
Electrical metering system supplies detailed energy usage information
The facility engineering staff at the University of Maryland, Baltimore, wanted more accurate, detailed energy usage information, and preferably segregated by building — a sub-metering capability that would allow the university to allocate energy costs to facilities based on actual usage. It was looking for a more advanced electrical metering system than the building pulse counters, which ultimately allowed for sub-billing to campus users.
Mike Krone, engineering project manager, considered a Square D PowerLogic power-management system. Once the system was selected and installed, he discovered unexpected added value that already has saved the university an estimated $100,000.
“After the RFP was completed and we installed the PowerLogic meters, we quickly realized that the PowerLogic meters could be very discrete with the kWh value per pulse, also known as pulse weighting,” says Krone. “At every location that we had a problem with in the past, the new PowerLogic meters provided just the right amount of pulses per hour for the automation panel to determine a reasonably accurate reading.
“We also wanted to save costs by putting the PowerLogic metering system on our existing fiber-optic-based ethernet network dedicated for our facility systems — building automation, access control, future fire alarm, etc.”

Electronically monitored fire extinguishers assist school in emergency preparedness
Mountain View Middle School, Goffstown, N.H., received a contribution of 48 wireless, electronically monitored fire extinguishers as part of a new fire safety demonstration project facilitated by the Safe and Secure Schools (S3) Program from the National Association of State Fire Marshals (NASFM).
Electronically monitored fire extinguishers can be more reliable and dependable than standalone models because they are screened constantly to make sure they are ready for action in the event of an emergency. The school's new system, en.Gauge, examines three characteristics of the extinguishers: presence, pressure and obstruction to access. The system sends an alert to officials if any of these three items are compromised. This system has given the school a wireless grid that allows it to connect other technologies and systems to the network.
Started in 2003 by NASFM, the S3 Program helps school administrators create safe environments through a software tool that pinpoints their most pressing safety concerns and provides solutions for the problems. The software currently evaluates two areas — fire/life safety and violence/vandalism. As NASFM developed the software, it identified electronically monitored fire extinguishers as a means to increase safety and stop extinguisher vandalism.
