This NEMA 7 compressor control panel example is a redesign of our customer’s previous standard panel. It’s primary function is to control an Air Compressor on an explosion-proof equipment skid located on an offshore oil rig with a 600V power system.
We redesigned the panel to reduce skid production cost. We provide a tall narrow enclosure with components arranged to allow rear conduit entry. This allows our customer to locate it on the edge of their equipment skid to improve access to the compressor control panel.
