Still Going Strong 40 Years Later!

Original H-822 valves were installed in mid 1970s, some originals are still installed and running!

We at Schenck Process FPM are happy to partner with Plattco to provide complete AF systems to the cement industry that reliably work 24/7/365 for the end user. Plattco provides a key component with the calciner emergency slide gate for high capacity calciner AF systems that helps allow the cement producer to increase substitution rates and increase the particle size of the fuel to reduce the fuel cost per ton. Plattco’s high temp calciner slide gate can handle the rigors of the inlet through both kiln start ups and upset conditions. The gate system Plattco assembles includes the gate itself, but also the air tank and accessories needed for fast action closing for emergency situations. This feature seals the upstream equipment and material from both the temperatures and positive pressure from upset conditions in the calciner and still allows the gate to close during power outages. This gate also allows the large fuel inlet chute to be closed when the AF system is not being used for maintenance or repairs. Plattco goes out of the way to make sure customer needs are met, as well as making sure their equipment exceeds the process requirements. With manufacturing and engineering in the US, Plattco is very responsive to our requests and maintains a very high-quality product at a competitive price.
