ATEX EQUIPMENT
specified for the application, with documentation to support it. The control equipment within the cabinet can be quite complicated and include valve islands, intrinsically safe valves, remote I/Os, components for filtration and pressure regulation as well as electrical connections and switches.
At the heart of the control system is the pneumatic island. For installations in zones 2/22, the choice is quite extensive, but to satisfy the demands of Zone 1/21, there are fewer options. However, this does not detract from the features that are available, in fact some of the latest offerings provide excellent integration and connectivity with components commonly used in these applications.
SEAMLESS INTEGRATION For Zone 1/12 installations, Bürkert’s Type 8650 (AirLINE Ex) offers numerous features and benefits, not least the ability to integrate
seamlessly with the Siemens ET 200iSP remote I/O system. This enables Bürkert valve control to operate within the Siemens software, which is commonly used in the pharmaceutical industry. One of the unique features of the Type 8650 is the ability to hot swap pneumatic valves without interrupting the manufacturing process. In an industry where any unexpected downtime can cause very significant financial losses, the benefits of comprehensive diagnostics and easy parts exchange can be readily appreciated. Production plants that are operating the Siemens PCS7 distributed control system can now seamlessly integrate Bürkert process control equipment that is tailored to each application. Furthermore, plants that operate in a non-Siemens environment can still take advantage of the Bürkert product lineup including the Type 8650 (AirLINE Ex).
STREAMLINED DELIVERY
Bürkert has exceptional experience in designing and building ATEX control cabinets at a dedicated facility that not only designs and constructs customised panels, but also certifies
the complete assembly before it is dispatched. This capability ensures a streamlined process for customers that provides tailored solutions within optimised timeframes.
Beyond the actual build of the control panel, in order to meet ATEX certifications, each product must be accompanied by the correct paperwork. Every project delivered by Bürkert is accompanied by a comprehensive documentation package that is supported by the company’s accreditations.
The Menden Systemhaus maintains a very high level of expertise in delivering control cabinets for installations in potentially explosive atmospheres. From initial concept to on-site commissioning, a dedicated team is assigned to each project to ensure continuity and that understanding of the specific requirements is maintained. Due to the multiple competencies within each team, it is possible to design compact, integrated solutions that often contain both electrical and pneumatic circuits and even fluidic connections as well. In this way, it is possible to deliver a single control cabinet, minimising space requirements as well as all the equipment that will control the process itself, which reduces commissioning time and improves final delivery.
