Using AC variable speed drives to save money by reducing motor power consumption is a matter of fact. Furthermore, offering a range of inverters with dual output and duty rated means users of Jaguar VXG drives can further increase savings by reducing the cost and size of the drive. When applying a variable speed […]
Byworth Boilers has improved boiler control and overall system efficiency by using the VSD’s loop control built into ABB’s machinery drive. The controller quickly responds to changes in demand for steam by accurately adjusting the water feed pump within its boilers. PID (proportional–integral–derivative control) is a control loop feedback mechanism widely used in industrial control […]
Eaton’s DE1 variable speed starter offers the advantages of both a motor starter and a variable frequency drive in a single device. The DE1 is a compact and easy-to-use device with the ability to change the speed of the motor with the simplicity of a contactor starter. Its design suits users concerned with the […]
The importance of a hotel’s hot water system cannot be underestimated. For the guests, it’s right up there with comfort, cleanliness, security and Internet access. For one UK hotel, installing ABB VSDs improved the hot water pumping and returned a 53% energy saving. The 200-room Daresbury Park Hotel & Spa came under the Britannia Hotel […]
Installing an ABB machinery drive to control conveyor speed has eliminated grinder breakdowns at an animal feed mill. Markedly, it uses simple motor current feedback from the animal feed grinder to control the conveyor speed. The VSD regulates the speed of a screw conveyor. This avoids overloading the the grinding mill with raw material. Using […]
