61 WorldWide Drilling Resource ® OCTOBER 2013 For links to these Web sites and more, visit worldwidedrillingresource.com Diedrich Drill has produced a heavy-duty rubber belt track system for use with their D-50 drill. The new system is rated to 24,000-pound capacity. Its track width was increased to 24 inches to further reduce ground pressure, and a more aggressive lug pattern increases traction. A two-speed drive system was incor- porated to provide extra power in low range, and speeds of 4.5 miles per hour in high range. HIGH TC GEOTHERMAL GROUT ™ by CETCO ® is a specially blended, high-solids bentonite which can be mixed with sand in a two-part, thermally- conductive grouting material to improve the performance of ground source heat loop appli- cations. It is an easy-pumping grout designed to match the thermal conductivity of the sur- rounding soil to create a perma- nent, flexible seal to prevent aquifer contamination. WWDR’s FEATURED PRODUCT: Flying “W” Plastics prefabricates high- quality, dual-wrapped geothermal pipe coils with a preinstalled u-bend. An SDR 9/11 molded u-fitting allows just two butt fuses per coil, which are furnished pressur- ized with crimped ends to assure no leaks are present.
