KPL proudly offers a premier intelligent variable frequency drive (VFD), integrated with a reliable bypass configuration. KPL VFD's are specifically engineered to work seamlessly on all KPL evaporative cooling equipment. A variable frequency drive eliminates the large starting inrush current of the compressor by ramping up voltage and
Frequency in a controlled time period. This allows running on limited dockside power, and also protects the generator from Overloading addition to eliminating inrush, the VFD will also run a compressor at 60Hz, even when input power is 50Hz, which allows full KPL capacity performance (230V only). The drive also protects the compressor by monitoring input voltage and output current, and will shut down if a power supply problem is sensed.

Eliminates compressor start inrush current more...- Kwality Power Limited
A Variable-Frequency Drive (VFD) is a system for controlling the rotational speed of an alternating current (AC) electric motor by controlling the frequency of the electrical power supplied to the motor. A variable frequency drive is a specific type of adjustable-speed drive. Variable-frequency drives are also known as adjustable-frequency drives (AFD), variable-speed drives (VSD), AC drives, microdrives or inverter drives. Since the voltage is varied along with frequency, these are sometimes also called VVVF (variable voltage variable frequency) drives.

Installing VFD for ID fan, FD fan and Blowers helps in saving electrical energy. In a typical boiler application, fans are provided with butterfly or multi-vane dampers, which is not adequate in precise combustion air control and electrical energy saving. Replacing it with drive helps in optimising the combustion air, thus reducing excess air level, helps in fuel saving apart from the electrical energy saved. We can provide automation along with drive for combustion control and pressure control. We do not advise VFD for boiler feed water pumps and heater circulating pump, as they reduce the pressure, which is not desirable. Combustion tuning is critical with drives and with our proven expertise, we shall offer the best solution. more...

Improving productivity and yarn quality: The productivity of a ring frame machine and the quality of the yarn depend directly on the end breaks. Production suffers and quality deteriorates when the number of end breakages is high. The ACS 800 drive together with the Spinning Control software provide a solution to most of the problems, resulting in an unequalled increase in production and flawless quality. The critical control areas for achieving increased Volumes and profits are the bobbin bottom and top where the number of end breakages is very high. The ACS 800 drive helps reduce breakages by using specially designed software for ring frame machines and state-of the- art motor control technology The speed of the motor is increased sleeplessly depending on the ring rail position and the doff build-up stage. This reduces doff time considerably, resulting in increased production volumes and greater profits. Easy to use: Unlike other solutions available on the market, the ABB more...
