Ah, you know ME not me, Middle East, this project is a repeated order, the client is happy with the decanter centrifuges from GN they purchased before, and now when they expend their business, they won more orders, they come back to us. 
IEC Ex is not a standard requirement, but if the local service provider wanna deal with international contractors, then all the equipment need meet the international standards, for electrical, it is IEC. Then you know, it is HSE requirements. Also in details, the design engineering, the welding, the inspection, the reports, the records etc. GN got the advantage of all these stuff, as from we start our business, we focus on that market, who always need pay attention to these details.
The real experience we ever learned from this project is what we sell is not only equipment, but also services. Though GN is only an equipment manufacturer, the service from the first time communication, what we define it as before sales, and along with sales, after sales, each and every step, there are services. Stay professional, keep client posted, and no surprise. Then the client will  stay with us. 
Except the key parts, like decanter centrifuge c/w control panel, which GN is really good at, this time the client is also purchasing the lifting frames, the special designed frame, telescope, continuous handrails, walkway, guardrails on. Feeding pump also lying on the bottom.
14 inch solid bowl decanter centrifuge with model of GNLW363 is one the most popular in GN production line. By equipping with the VFD control panel, operator can run the bowl from 0 to 3200 rpm (designed maximum speed is 3900RPM).  GN is adopting centrifugal casting technology to make the bowl so that the bowl would be more solid and dense. The bowl material is from duplex stainless steel 2304 that is with better machinability much better than SS316. 
GN makes the VFD control panel as positive pressure principle to realize the explosion proof. Normally, the control panel is equipped with 3 VFDs for decanter main motor, back motor and feeding pump. GN can design the interlock system between the pump feeding and running of decanter to ensure the smoothly working of the equipment, therefore, GN recommends to set up the control of the feeding pump in GN VFD panel even client prefer to using their own pump. 
The last but also the most important part is GN is delegating to offer our client a perfect experience of getting a solution, not just buy / sell, it is always working together to solve a problem.
