Schramm T685EX


The T685EX is the drilling contractor’s rig of choice for reverse circulation mineral exploration applications where big air is required in a highly mobile, heavy duty package.

A sliding angle mast and a variety of RC accessories, combined with track or truck mounting offer site specific equipment solutions for almost any application. Automated pipe handling systems are also available to provide hands-free operation for loading and unloading drill rods. Power breakout systems are available to complete the pipe handling package.

Schramm’s patented air-Control monitors cooling system temperature and compressor volume requirements to provide maximum power efficiency and fuel savings up to 12 percent.

Any climate, any terrain, Schramm rigs are built your way, delivering maximum performance and reliability in the most extreme environments on earth.

  1. air-Control®

    The revolutionary Air Control system manages the compressor and variable speed fan controls to maintain a constant pressure and temperature on the system with a simple interface. This automated Compressor control system matches the volume of air created to the volume being consumed by modulating the positioning of the inlet control valve. The valve position is controlled by an attached cylinder. The compressor sump pressure indicates whether the compressor needs to make more or less air to match the consumption. The control system is capable of artificially lowering the pressure below system demand, or lowering the volume below potential with operator overrides. Read More
