S&C's PureWave UPS Provides ?Critical? Power Protection to Missouri Hospital
Franklin, WI
December 12, 2003 -? Surgeons at a central-Missouri hospital-concerned about frequent weather-related power outages-demanded a higher degree of power quality than possible from the facility's existing backup generator.
The hospital's consultant chose an S&C PureWave UPS? System to maintain uninterruptible power to the surgical suites.
The 625-kVA / 500-kW PureWave UPS System will keep the lights and other vital, life-saving equipment operating during the 10 seconds it takes for the backup generator to start upon loss of the utility power source.The PureWave UPS System will be installed as a part of an infrastructure improvement project to be completed in May 2004.
Construction costs have been minimized because PureWave UPS Systems are designed to be installed outdoors . .
. eliminating the need for costly indoor space.Critical-power solutions are the specialty of S&C's Power Quality Products Division. Their PureWave Systems are used worldwide to deliver reliable protection from power quality problems such as voltage sags, swells, and flicker, and complete outages, and to improve power factor.S&C Electric Company, headquartered in Chicago, IL, specializes in the development and manufacture of innovative products and services for the electric power industry. S&C's family of PureWave? Power Quality Systems have been installed at critical-process facilities worldwide to deliver reliable protection from the power quality problems that can disrupt operation.

Electric Generators: Understanding Your Power Needs
In order to choose the right emergency power source and to size it properly, you need to understand something about the power requirements of the devices you plan to operate.
The basic unit of power measurement is the watt, and with an emergency power source there are two wattage ratings that are important: steady-state wattage and surge wattage. A normal 60-watt incandescent light bulb requires, as you would expect, 60 watts, and it requires that wattage both when you turn it on and while it is running. A ceiling fan motor, on the other hand, might require 150 watts to get it started and 75 watts while it is running. That extra wattage to start the motor is called the surge wattage and is typical of anything that contains an electric motor.
Here are the usual wattages of some of the devices found in a typical household:
Device Typical wattage Surge Wattage
Light bulb 60 watts 60 watts surge
Fan 75 watts 150 watts surge

eCycle Offers High Efficiency Auxiliary Power Units (APU) for Trucks and Locomotives- Provides Anti-Idling Solution
Temple, PA (ContentDesk) June 30, 2005 -- eCycle, a manufacturer of high efficiency generators, is pleased to announce its new line of auxiliary power units (APU) that offer up to 10 times the current of similar products presently on the market.
eCycle's APU was designed to answer industry's demand for lightweight, high efficiency mobile DC power solutions in compliance to the anti-idling laws that are being mandated throughout Canada and the United States.
These units are perfect for vehicles requiring additional DC power as part of a total generation system.
Depending on the application, the units can be configured to produce up to 6kW at low voltage (14, 28 or 72VDC) with current up to 400A.
Until now, there has not been a generator that can produce high current in a low voltage system.
eCycle's unique electronically commutated motor/generator (CMG) utilizes SolidSlot? technology that replaces traditional windings with bars of copper. ...

Technology Leads To Reduction Of Nitrogen Generators' Size
As technology improved, so did the nitrogen generator systems, and recent discoveries have led to the reducing of the nitrogen generators size.
These new-generation, small size nitrogen generators are very effective and reliable, and they operate automatically, with very little maintenance required.
The main difference between these nitrogen generators and the normal ones is the size, these small capacity units only take up 60% of the space used by a usual nitrogen generator, saving 40%.
Another difference is that these nitrogen generators do not supply a 99.99..% pure nitrogen, but something around 95% pure, which is not a disadvantage because most users and laboratories don't require 99.99..% pure nitrogen. The nitrogen's purity may be increased to 99.5% if the user desires to do so, by absorbtion or, cheaper, by adding a process to the nitrogen generator, that runs the resulting gas through a special filter that reduces the oxygen concentreation...
