Our Mission


Drill Cool Systems is the original manufacturer of Mud Coolers also known as Geo-Coolers. For more than 35 years we have been proud to offer the best mud cooling systems worldwide. Our focus is on controlling wellbore temperatures through the cooling of drilling fluid at the surface. Drill Cool provides unique solutions for controlling drilling fluid temperature for oil, gas and geothermal operations throughout the world.



Drill Cool Systems started in Bakersfield, CA under the Kern Steel Company in 1978 by Elwood Champness. Elwood went on to invent a piece of equipment that could control the temperature of drilling fluids so that operators could drill safely on Geothermal wells. In the late 1980s Drill Cool Systems widened their reach, with their first international project in Indonesia. By the mid 1990s Drill Cool Systems experienced considerable growth in the Geothermal and Oil & Gas industries and continues to operate as the global leader in drilling and well safety today.
