Important Announcement

A message from Power Dynamics Innovations LLC’s HDD Service and Parts Department

Today PDI continues to expand our “Dynamic Power” Rig Technology to the HDD Market, announcing our Dynamic Power TM “Exit Device”. Attached is our product brochure for your review and consideration. If you would like to see our “EXIT DEVICE IN ACTION” please email or give us a call. We would be happy to
send you the video of our technology in action.

Our Exit Device is a self-contained device used to break drill pipe joints free, so that it can be disconnected from the drill string prior to utilizing the rig for rotation once the joint is broken loose.



PDI began modifying and repairing other Manufacturer’s HDD’s in 2012. Our customers began to request new units that could be customized in a way that made them Simple, Reliable and Easy to Maintain. PDI’s “Dynamic Power” Rig Technology delivers that requirement. We built our first 500K HDD Maxi Rig in 2013 and we continue to build and service with the highest regards for quality in everything we do.

At PDI we do everything from minor repairs to major overhauls. We have done extensive reworks and are capable of reengineering and designing rigs to make them perform better to meet the needs of our customers. We also custom build Vise Assemblies, Jaw Blocks, Carriage Assemblies, Hydraulic Power Units and supply
parts for everything from top to bottom.

To minimize equipment downtime, PDI offers on-site 24/7 service. We can mobilize our skilled service technicians within a few hours in most cases. We will travel to anywhere in the Continental United States, Canada, Mexico, Central or South America.

If you are interested in quotes for equipment or service please give John Holland a call on his direct line 601-229-0967, cell 601-408-9812 or email jholland@powerdynamicsllc.com.
