This is a pneumatic booster system designed and built for a pulp & paper firm to control air padding pressure to paper machine, all tubing and fittings are 316 Stainless Steel

Because of my past experiences working for Moore Products Co and Bailey Controls I am in a unique position to develop pneumatic and fluidic control systems.

Are you locating PCs in an industrial environment?  If so you should consider having them installed in a computer case designed to survive in a hostile area.  We can provide enclosures for less than $300.00 

We can also provide custom air or nitrogen purged enclosures for electrically hazardous areas to meet Class 1 or 2 Groups C&D

I designed the Digester control console on the right way back in 1979 for a pulp & paper firm in Virginia. 

It was truly state of the art at the time being one of the first DCS systems (Measurex). The plant manager of the P&P firm directed me to finish the console with a paint that was "Scratch Proof", I finally convinced him to accept Formica and had it built at Custom Engineering in Tucker Ga.
