Pneumatic Panels have been used since the beginning of the last century, and some of the inherent advantages that made them successful then are still true today. Pneumatic systems minimize ignition hazards in explosive areas and are highly reliable.

While modern PLC based control and alarm systems offer more technical sophistication, there is still a need in certain applications for simple, rugged, and easily maintained control systems. ESL continues to manufacture a multitude of Pneumatic Control Panels for the petrochemical industry.
