CET systems on track

The new vehicles are in action at Manchester Airport railway station, extracting sewage from the toilet holding tanks and supplying wholesome water for washing hands and for toilet flushing, on trains operated by First TransPennine Express. 

Hygiene and safety were key priorities for the rail operator, ensuring that both stringent safety and hygiene requirements for platform work were met, together with ease of maintenance of the vehicles and the CET Systems. 

The construction concept of the Vogelsang's CET systems is based on the rotary lobe pump principle. A vacuum is directly generated by the Vogelsang's proven rotary lobe pump. The rotary lobe pump easily maintains a vacuum over a long distance and discharges to mains. This allows for trouble-free operation requiring less space and maintenance. The result is high availability and less down time. Each mobile CET system is custom made to meet the customer's requirements. 

Vogelsang's non-drip coupling system meets the hygiene priority by eliminating spillage during sewage extraction or water filling. Based on the Bradshaw PFB1500 chassis, the AC drive technology addresses the safety priority with multi braking systems, lighting, safety cut out and audible warnings as standard. Modifications, which include rear roll out batteries, ensure that the vehicle is able to be in operation for 24 hours a day.
