Dust, debris, water, and other contaminants commonly found in machine shops, robotic plants and warehouses can wreck havoc on sensitive equipment used for networking and controlling machinery. Using standard enclosures or racks to mount important equipment in unclean environments can greatly reduce operation life as dust and other contaminants begin to build up. This can eventually lead to or result in time consuming and expensive system shut downs. More
