Comparing with the VFD Controlled decanter centrifuge, the fixed speed one still has its benefits, like the compact structure as a whole with the decanter centrifuge and its control panel, and the easier operation, no need to adopt an extra air compressor, and etc.
But still, the VFD controlled decanter centrifuge is the only choice accepted by the end users. Because the positive pressurized control panel is more suitable for the high temperature conditions, and the easily changeable rotating speed, then the G force accordingly helps the VFD controlled decanter centrifuge to be suitable for more applications like the middle speed and high speed.
GN Centrifuge on Skid
As the leading manufacturer of solids control and waste management systems and equipment, especially for the decanter centrifuges, besides the fixed speed decanter centrifuge, GN also produce normal VFD control panel decanter centrifuges and also the positive pressurized VFD control panels for decanter centrifuge. And GN Solids Control is the only China manufacturer who has positive pressurized control panel for option.
In order to change a fixed speed decanter centrifuge, take the best seller model GNLW363CG decanter centrifugethe end user need to change the 11kw back motor for the decanter centrifuge into a VFD motor and also prepare a VFD control panel for changing the fixed speed control panel.
About the VFD control panel, GN has double VFD ( centrifuge main motor and back motor), three VFD ( centrifuge main motor, centrifuge back motor and pump) for option. Depending the Exproof options, there are flame proof VFD control panel which is similar as other Chinese suppliers, and also the positive pressurized control panel for option. If the choice is a positive pressurized control panel, the end user should prepare an extra air compressor at jobsite as the air source of the control panel.
