Comparison of Compact Fluorescent to Incandescent Bulbs
Published by Dranetz Technologies, Inc., Case Study With the proliferation of Compact Florescent (CF) lighting, we thought it would be interesting to do a side by side comparison to an incandescent bulb using our new Energy Platform EP1. Not only is it a great demonstration of the capabilities of the EP1 but it’s also an opportunity toContinue reading “Comparison of Compact Fluorescent to Incandescent Bulbs”
Glass Factory Failure of Electronic Controls
Published by Dranetz Technologies, Inc., Case Study The customer was experiencing repeated failures electronic controls and instruments in a new glass factory. The factory had been imported from a 60hz country to a 50hz country. In this case, the new factory capacity was reduced by 50% or more do the frequent shut downs and stoppages. The costContinue reading “Glass Factory Failure of Electronic Controls”
