Compressors. Aerospatiale, the French aircraft manufacturer, installed a 150kW Powerboss to a twin screw compressor fitted with a 132kW Siemens motor. Powerboss produces an annualised saving of 30,572kWh. This represents a simple payback of just over 1 year.
Rock Crusher A 400kW ‘Rockmill’ capable of crushing 65 tonnes of granite in around 5 minutes was suffering from excessive starting currents, even when started unloaded. A Powerboss PSO 400 provided an effective soft start solution with complete motor and system management. It was noticed that the motor spent over 40 minutes in each hour operating in either a low, or unloaded condition. During these periods Powerboss reduces the power consumed from 181kW to 153kW. The soft starter that paid for itself!
Fans - A drying oven, which operates for 24 hours per day and 5 days per week, incorporates 6 - 11kW fans, which have a measured duty point of 8.7kW . When fitted with the Powerboss dynamic motor controller and energy optimiser the power reduced 5.36kW The purchase cost of the Powerboss was recovered in 27 weeks. Once fitted to all six fans, the annual running cost of the oven will reduce by more than £5,000.
Contact free starting - Powerboss can also be used for contactor-less switching of frequently starting motors, such as are used on reciprocating compressors.
Other applications - These are just a small selection of applications. Others are as diverse as a Vacuum Pump at Stoke Mandeville Hospital, to sewage and potable water pumps. From compressors in a British Rail Engineering workshop to lathes and grinders in a factory making wood burning stoves. For many people massive increases in energy costs have become an unpleasant fact of life. Now you can do something about it !
A proven product - Powerboss has grown out of almost a decade of research and development in the field of intelligent motor control. There are now literally hundreds of satisfied customers across thousands of installations, saving industry millions of pounds in energy costs. Powerboss has full CE & UL certification. and is year 2000 compliant.
