Fully redundant C1D1 5-ton system for a horizontal drilling rig

Full explosion proof redundancy for drilling platforms and critical on-site support buildings

As one of the dirtiest, noisiest, and most hazardous applications for which we provide systems, drilling rigs have a special set of needs, most importantly full redundancy. Unplanned stoppages of the drilling process can potentially cost thousands of dollars for each minute the system is down. There are several applications, unique to each part of a drilling process.
