Global Distribution Network
Amikon supplies industrial automation parts to more than 150 countries, covering a wide mix of regions. The Americas, especially the USA and Canada, still rely quite a lot on replacement parts. Many sites there are older facilities like refineries or chemical plants. Europe is similar, with countries such as Germany, UK, France and Italy. A lot of work there is about keeping existing systems running rather than new installations. Asia-Pacific includes China, Japan, South Korea, Singapore and Australia. Industries there range from semiconductors to shipbuilding and mining, depending on the country. Middle East and Africa, like UAE, Saudi Arabia, Qatar and South Africa, are more focused on energy-related operations, mainly oil, gas and power sectors.
