Pipe screw conveyors with ATEX approval – 36828

3 pcs. tubular screw conveyors designed for transporting wooden fibers and placed in an ATEX zone. The inside of the pipe screw conveyors are classified zone 20.  Tubular screw conveyors, also called pipe conveyors have a great ability to transport higher volumes, as the material cannot fall back in the same way compared to a trough or u-shaped screw conveyor.

Important points to know when working in ATEX zones:

As the end client, you have the responsibility to determine exactly which ATEX zone the screw conveyor shall be placed in:

• Gas environment
• Dust environment
• Which zones apply inside the screw conveyor and outside and around the screw conveyor

BEMA has the experience and is capable of designing and manufacturing the screw conveyor to obey any of the above set requirements within the ATEX regulations. BEMA will also handle the full documentation that follows and send it to the notified body, if required.

In general, a full package, so you as a customer, can rest assured that all requirements and approvals are met and documented correctly. For example, documentation will consist of:

• A machine drawing with reference to the defined ATEX zone/zones
• ATEX marking on the conveyor and gearmotor, if necessary
• Complete documentation with a declaration of conformity
• Approval certificates from the notified body, if used

At BEMA, we mechanically design the screw conveyor for the defined ATEX zones. We design to exactly obey the requirements without building unnecessary means into the screw conveyor.

This specific case is approved for ATEX zone 1D inside the conveyor and 3D for the surroundings outside.

If you require a similar tubular screw conveyor solution with ATEX approval, please feel free to contact BEMA at any time and discuss the possibilities. Just remember that you are responsible for finding your ATEX zone classification before we can start designing.
