The Thunderstorm I is a mud recycling system designed for use with HDD rigs less than 50,000 pounds, with a fluid capacity of 1,500 gallons. Tanks are coated with an Oilfield Grade Liner for longevity and ease of cleaning. The system mixes and cleans drilling fluids using three-5 inch cones. It is designed for ease of mobility and small footprint, and has a three-panel double shaker that deposits cuttings at the rear of the unit for ease of collection and occupying a smaller space.
