VFD Drive Systems Solutions

VFD drives are modular designed architecture (MDA) and offer the latest control and Power Design on the Market. They are a combination of high reliability, durability, and ease of maintenance. These units are provided both in water-cooled and air-cooled VFD drive systems configuration with a horsepower range of 300 to 2000 HP.  These units can be load shared to achieve capacities up to 6000 HP.  Each Drive system can be fully customizable, engineered, and tested to the customer need. Each unit is front assessable for ease of maintenance and less downtime. We utilize GE ConverTeam VFD technology for its reliability and common spares across existing fleet rigs (Other VFD manufacture Usage can be discussed with MRI Customer Sales Contact).  Multi-use TD/RT VFD drive allows for operator assigning one drive to two functions without cabling or system changes.
