Specialties
Obsolete electrical equipment, drilling rig systems, and legacy SCR and DC drives.
01 / OBSOLETE & LEGACY
We source discontinued breakers, drives, controls, and modules, working from the complete manufacturer number and the equipment it belongs to.
02 / DRILLING RIG ELECTRICAL
Ross Hill and NOV SCR systems are central to what we do. AC and DC control modules, contactors, power sections, generator controls, and the electrical hardware around them.
We also source the drives, VFD controls, motor control, and distribution equipment used across modern AC rigs.
03 / SCR & DC DRIVE SYSTEMS
We source legacy SCR and DC drive equipment across Ross Hill/NOV, GE, Reliance, and other lines.
04 / SURPLUS & RECONDITIONED
New, new-surplus, used-tested, and reconditioned equipment each have a place. What matters is knowing what’s being offered for your application.
We disclose condition before sale and check current availability before quoting. Ask for photos and the available testing or reconditioning information on the specific unit.
Send the complete part number or a nameplate photo, the equipment details, quantity and need-by date.
