WEG payback calculator for pump and fan motors goes online

Quickly determine energy savings, payback times and reductions in CO2.

With motors running for thousands of hours per year, WEG's new online payback calculator for electric motors enables pump and fan users to quickly determine energy savings, payback times and reductions in CO2 emissions, when evaluating new projects, or the replacement of existing motors with higher efficiency types.

The payback calculator is designed to produce comprehensive reports, and can be used to compare a wide range of variables, based on usage and component specifications, to find the best option for any application, including multiple motor installations. The payback calculator is not limited to WEG products: it can compare efficiencies with any product on the market. The payback calculator is for use on desktops or portable PCs and is easily downloadable (www.weg.net/green/uk/save-money.html).

In addition, for engineers on the move an energy saving BlackBerry App is also available downloadable: (www.weg.net/green/uk/blackberry-apps.html). The tool can calculate the payback time for premium versus standard efficiency motors in new projects, and the mobile App is equally useful in assessing the running costs of existing motors, to determine the repayment time for replacing them with more efficient types. It also enables users to calculate and display the payback time for a new motor against the cost of rewinding, following a motor failure. Here the system even takes account of the fact that rewound motors may experience a drop of up to 2 points in efficiency.

The simple-to-use online App offers the benefits of dual set-up options, for kW and HP, and Euro, Dollar and Pound as default currencies, with the facility for other currencies via a šcustom' function. In addition, coefficients for CO2 emissions are provided for coal, oil, natural gas and other fuels.
