New territorial conquest for the Espoo factory: ATEX fan for potentially explosive premises
When the Norwegian arm of an international company specialising in medical engineering and biotechnology needed an ATEX class vapour recompression fan, Fläkt Woods received an enquiry from their Norwegian partner EPCON Energy & Process Control AS about the company’s willingness to deliver such fan at short notice. Fläkt Woods’ factory in Espoo Finland rose to the challenge: the order would further expand and build on Fläkt Woods’ excellence in industrial fan solutions.
Access to know-how of the entire group
Fläkt Woods’ local units can draw on the extensive ventilation and air treatment experience of the international Fläkt Woods Group in their own projects. In this case, ATEX expertise was provided by the Group’s factory in Meyzieu, France. When the requirements of the Directive had been examined with Det Norske Veritas classification society, Norwegian EPCON was able to submit a bid for the project based on Fläkt Woods’ calculations. Once the supplier had been selected, the planning of the fan was started in August 2005.
Industrial equipment subject to strict ATEX requirements
The fan under construction came under category 2 of the Directive’s industrial equipment group, which requires compliance with a high standard of safety. The standard defines temperature, accumulation of static charge, component robustness and the limit values applying to the distances between moving and stationary parts.
ExVel High Pressure Blower – a good starting point
The Espoo factory’s ExVel High Pressure Blower design provided an excellent mechanically sound starting point for the ATEX fan. Furthermore, to prevent sparking, a critical factor as far as the risk of explosion is concerned, all parts were earthed and an anti-arcing screen was built around the impeller, the shaft seal and the clutch. Full machine documentation and an over 50-point risk analysis was drawn up as part of certification.
Many industrial applications for ATEX fans
The fan was ready for delivery in December 2005, just four months after the order was placed. The know-how acquired during the project and the diverse application of the ExVel High Pressure Blower mean that in the future Fläkt Woods’ Espoo factory has the capability to design and deliver ATEX certified ExVel High Pressure Blowers for a wide range of industrial processes.
