Control Systems & Software

The Leader in Field Proven Controls

Stewart & Stevenson’s data acquisition and control centers provide a centralized command center to control all of the critical well site equipment while monitoring, recording and supervising the fracturing treatment. Data vans reduce the number of equipment operators required to complete the treatment while greatly improving job quality through centralized real-time data gathering and presentation.

Stewart & Stevenson’s IPC-PC interface provides control of up to 24 fracturing pumps at a single operator workstation. The AccuFrac-PC interface provides control of multiple blenders, hydration units and chemical additive units from the Data Acquisition and Control Center. UPS systems and solid-state CPU components provide reliable operation with backup systems.

Our control systems are available as discrete components, giving our customers the ability to upgrade existing equipment.
