SCR Bay Components

The supporting hardware inside the SCR house, contactors, blowers, panel meters, and instrumentation for Ross Hill and NOV drives.

The modules get the attention, but a Ross Hill / NOV SCR drive lives or dies on the parts around them, the contactors that switch power, the blowers that cool the bay, and the meters and instrumentation the driller reads. We source those too, and cross-reference the components to their real manufacturer numbers.
