Power Capacitors App leaked prior to official launch


Power Capacitors App leaked prior to official launch.

Power Capacitors App gets nearly 700 downloads from word of mouth alone!

Power Capacitors Limited, were all set to officially launch their free Power Factor Correction Android app this week when they discovered the world wide web had already done it for them. As preparations were being made for the announcement they discovered there had already been nearly 700 downloads from word of mouth alone. Not only does this clever application calculate the KVAr requirements for Power Factor Correction installations but it also shows the amount of carbon you can save per year by installing Power Capacitors PFC.

Although it was designed for engineers its of great interest to both finance and environment professionals looking to reduce their costs and carbon production. It also includes a clever tech-contact feature which allows you to get a quick answer to any power quality problem straight from your device. “Its as near as we can get to having a power quality expert right there with you on site” said Power Capacitors Business Development Manager Michael Dawson. “If some friendly advice over the phone does not get to the bottom of it we are usually in a position to come to site free of charge to offer some suggestions.

We always felt there was a need for this kind of app and so we teamed up with one of the best technical app companies in the business “<a href="http://www.procertssoftware.com&quot; Pro Certs Software”.

Most industrial and commercial premises have the potential to be suffering from a poor power factor and needlessly paying “Reactive Power” charges. If there are reactive charges on your energy bill then Power Factor Correction can make them go away with a typical 2 year return on investment. If you don’t already have it you can download it free at <a href="http://electrician-apps.com/app/power-capacitors/"http://electrician-apps.com/app/power-capacitors/
