Anti-Rotation Device and Circulating Head



Tartan’s patented Anti-Rotation Device (ARD) controls and releases reactive torque generated from the use of down hole drilling motors. The ARD mechanically removes the reactive torque from the tool string at the rig floor. 

To increase worker safety, Tartan has designed the ARD so that it does not have any external moving parts exposed to the service rig personnel. The ARD also acts as the circulating head with flow passages and screens, which allows fluid to be circulated to operate the motor.
