Although especially designed for safe reactor charging, the PTS powder-transfer system (photo) has proven itself in many applications of a much wider spectrum than traditional reactor charging. The PTS-System is exempt from ATEX 95, and therefore does not need an ATEX certification or confirmation. The system does not create its own ignition source and therefore is intrinsically safe. By means of active powder transfer, by a combination of vacuum and pressure, the PTS is able to replace risky open manual handling. Powders can be transferred from almost any receptacle, such as sacks, big bags, drums or storage vessels, and be discharged into any type of receiver. The system can be mounted directly on a vessel or is available as a mobile unit. The PTS is fully CIP (cleanable in place) and guarantees hygiene and complete containment. — Dietrich Engineering Consultants S.A., Ecublens, Switzerland
