Big Bowl, large Extruder rate, PLC control is the development trend of centrifuge production, especially for oil & gas drilling fluids decanter centrifuge. VFD and Hydraulic are 2 kinds of drive method, both of them have their own advantages, but VFD control decanter centrifuge is much more popular and easy maintenance at present. Here I will introduce and compare some world famous VFD big bowl decanter centrifuge.

According to the chart above, their bowl size, bowl length is similar to each other, but the G-force, motor power, differential speed etc specification has big difference. Also the treating capacity varies by different model, different brand centrifuge.

VFD CONTROL PANEL

VFD CONTROL PANEL

GNLW553VFD centrifuge still have many points to be improved, for example, it is completed electric drive, no hydraulic package, and it is mechanical controlled on the VFD control panel, no touch screen, no PLC control, GN will improve it as PLC control soon.
