Click on Nema 7 Panel Submittal.pdf to see our FOR APPROVAL documentation prior to PRODUCTION.
This panel is used to control Air Compressors. Our customer produces equipment for specialty compressor applications. They normally purchase packaged compressor skids with a control panel. When they provide NEMA 7 Explosion Proof Class 1 Division 1 Compressor skids they have us produce the NEMA 7 Panel. They picked us because we adapted their panel design to simplify how the panel mounts on their skid and how they run conduits to it.
This is an example of how optimizing a panel design for a specific mounting location can reduce production costs. The tall narrow panel with conduit penetrations through the rear of the enclosure allows our customer to conveniently mount it on the edge of their skid and use fewer conduit bends to connect to it. It includes a Power Distribution Block, a Phase Monitor, two Motor Starters, 120V Transformer, Pilot Devices, and a Window to view the internally mounted (on rear panel stand off bracket) Hourmeter.
