Design Engineering




With multiple engineering departments under one roof, Pilon can ensure seamless design of any system. Our Pilot Plants will always be up to the mark as there is great co-ordination among all the disciplines working as a whole unit. Pilon has in-house capability of software development. This ensures a smooth integration between process & instrumentation departments.
