Pneumatic cabinet 2.0 offers more safety and user friendliness
Following a risk analysis, STAG realised that the existing control system in the version 1.0 pneumatic cabinet no longer met their safety requirements. TRI-MATIC's engineering department developed the pneumatic cabinet 2.0, a purely pneumatic solution with two-hand operation, an emergency stop button and process visualisation using a diagram.
The project planning of systems in bulk materials technology - from the concept to the complete turnkey system - characterises STAG's core business. STAG is internationally recognised especially for the development of innovative system solutions and for its broad expertise in bulk solids technology.
Initial situation/Challenges for the customer
Following a general internal risk analysis, STAG realised that the existing control system in the version 1.0 pneumatic cabinet no longer met its safety requirements.
The pneumatic cabinet 1.0 controls the filling adapter and shut-off valve. As soon as an emergency discharge occurs, the filling adapter which serves as a connecting link between the line and the filling container is required. When the emergency container is filled with ash, the slide valve is closed via the pneumatic control. After the internal timer has elapsed, the filling adapter is then lifted up. The container can then be changed.
The aim was to optimise the existing control system and develop a purely pneumatic control system with the safety of two-handed operation, an emergency stop button and process visualisation.
The pneumatic cabinet version 2.0 has improved the safety and user-friendliness of the system.
Solution
The project manager, Kevin Nesensohn, initially enquired with various suppliers. TRI-MATIC's engineering department developed a purely pneumatic solution with two-hand operation, an emergency stop button and process visualisation using a diagram. This solution was able to fulfil all the technical and safety requirements in the version 2.0 pneumatic cabinet. The original cabinet size could also be retained, which was another important criterion.
In addition to the technical solution, the fast communication and customer proximity were additional convincing points in the overall package, so that STAG decided to realise the project with TRI-MATIC.
Results
The pneumatic cabinet version 2.0 has improved the safety and user-friendliness of the system. The process is shown schematically. The operator can see from the analogue pressure gauges whether the process is complete or not. The control system works perfectly and its operation is much more customer-friendly. STAG's current safety requirements are met.
The project manager, Kevin Nesensohn, summarises: «Our customers are our top priority. User-friendliness and safety are very important to STAG.»
