In the Petrochemical Industry alone, pneumatic control systems have been used since the beginning of the last century. Yet, some of the inherent advantages that made them successful then are still true today. These advantages include safety in hazardous areas, heavy-duty construction, ease of use, and maintenance.
While modern PLC based control and alarm systems offer more technical sophistication, there is still a need in certain applications for a reliable, rugged, basic and easily maintained control system. ESL still manufactures these pneumatic control panels to suit any application.
