These more extreme cases for the Southern mine underscore how critical the initial mine temperature is with respect to occupancy derating
Here the furnaces were tested using the manufacturer's recommended altitude derating
schemes, the production (sea level) settings, and several settings in between.
The curves do not have a 10% derating
and in fact the external trace chart is not conservative for what it actually represents.
engine power solves the engine durability problem, it creates one for the customer in terms of reduced performance and productivity.
"The BTCPower S15 Series converters are designed to operate with no air flow in ambient temperatures between -40 and 60 degrees Celsius ambient with no power derating
," said James Lau, president of Broadband TelCom Power, Inc.
Sound attenuation options have been added for noise sensitive applications and this generation of Cat gen-sets include a large extension box for better cable access, a broad voltage generator that can handle a wider voltage range without derating
, and a factory-built and assembled weather proof enclosure.
The problems of an oversized heating system can be partially corrected by derating
. This refers to adjustments that reduce the rate at which fuel is burned.
The filters have an operating ambient temperature rating of -25 to +85[degrees]C with derating
Reducing the transfer rate meant derating
generators during periods of wet coal--also not an option for a plant supplying a major metropolitan area.
* 3 W across a range of operating temperatures from -40[degrees] to +95[degrees]C with model-dependent derating
The devices operate over a temperature range from -55[degrees]C to +105 [degrees]C with voltage derating
The drive offers true side-by-side mounting without any derating
due to its compact, bookstyle design.
