VFD centrifuge and FHD centrifuge is widely used for drilling mud system. It can be used for drilling mud treatment, drilling cutting treatment, waste water treatment, and oil sludge separation.
As FHD centrifuge price is high. And the FHD system is normally complex for maintenance and repair. As this reason, VFD centrifuge is more popular than FHD centrifuge. GN Solids Control is a professional manufacturer for VFD decanter centrifuge. Other companies normally make VFD control panel with fan for cooling. It is not suitable for high temperature area. And it is not self cooling. GN Solids Control is capable to make positive pressurized VFD control panel, which can be equipped with A/C cooling system or vortex tube cooling system. It is GN special design. Both A/C and vortex tube system are for self-cooling. They can capable for high temperature area.
Many clients do not know the difference between Vortex cooling system and A/C cooling system for the centrifuge positive pressured VFD panel. Here is a general introduction of the difference difference between Vortex cooling system and A/C cooling system for the VFD
1) Positive pressured VFD panel with vortex cooling system is for CNEX Zone 2.
The video will make you clear about Vortex tube cooling system.

2) Positive pressured VFD panel with A/C cooling system is for ATEX Zone 1.
The A/C used for VFD panels looks the same as the AC we used for rooms and office, but explosion proof and suits for +55C degree. The cooling performance is better than vortex tube. Price is higher. It is specially used for high temperature areas.
With neither Vortex tube or A/C self cooling system, they can keep the internal of VFD panel around 25C degree.It is the most suitable temperature for electric components. The temperature can protect electric components and extend their lifetime.
