Engineered to handle the speed of geothermal drilling - drilling multiple borings per day as compared to a single hole during a multiple-day process - DRILLMAX® drill rigs exceed expectations in tough conditions. While geothermal drilling tends to prioritize overall rig size and weight, drilling speed, and cost per foot, options such as sandline winch or pipe spinner systems can be added to minimize equipment on the geothermal drilling job site.
DM250: suited for residential or small commercial jobs.
DM450: designed for large residential or commercial jobs.
Using their DRILLMAX® DM250, company owners claim completing 15 bores to 305 feet through tough, plastic clay 80 percent of the hole - just the two of them. One ran the geothermal drilling rig. One prepped loops for installation with the mud cleaner.
The Rocky Mountains were no trouble for the DRILLMAX® DM450 geothermal drilling rig. Owner claimed the DM450 drill rig outproduced the combined footage of three other rigs drilling multiple borings per day to install geothermal loops.
