Electrical motors are one of the main electricity consumers and it is estimated that electric motors account for almost half of the energy used in Europe and almost two-thirds of the energy used in industry. Most engineers know that installing VSD inverter drives will save energy, especially for fan, pump and compressor applications. The […]
Designed for fan and pump applications up to 630kW the Mitsubishi Electric’s F700 variable speed inverter drive offers a wealth of benefits for the user and installer. The built in energy optimisation software boosts motor efficiency to unprecedented levels and intelligently maximises energy savings during acceleration, deceleration and constant speed operation. It also […]
Significant energy savings can be achieved by installing variable speed drives to the fans and pumps used in building services. The Schneider Electric’s (Telemechanique) Altivar (ATV) 61 has been designed to manage and monitor your building’s HVAC and pumping functions. The Altivar 61 drive reduces energy costs by adjusting motor speed to the […]
Quickly estimating the energy savings available by installing variable speed drives to motors is simple as their power consumption is governed by the cube law (see earlier article). In the example given, a 10% speed reduction saves 27% of the running cost. Energy savings calculators are also available for more complex applications, but flow applications are particularly suited to this type of […]
Finding new ways to save energy year after year is a major challenge when you have an ongoing energy saving programme. That’s why Trelleborg’s flagship Industrial Anti-Vibration Mounts plant in Leicester, UK, has installed a Mitsubishi Electric SCADA solution with integrated MX4 Energy software to monitor and control the plant’s energy use. Since its installation […]
