TAKE THE OPPORTUNITY OF A MOVE TO BRING EQUIPMENT UP TO
STANDARD
Following the arrival of a group company on the same site, the historic company
(manufacturer of top-of-the-range sailing boats) had to move its woodworking shop to
another building. The existing installation was no longer up to standard and no longer
provided the necessary performance for the protection of operators and production tools.
The company had a park of 15 machines (saws, machining centre, routers, planer, edge
bander, sander and suction tables) and wanted to replace its obsolete centralized sawdust
and wood chip extraction system.
The new installation had to ensure complete protection of the operators, guarantee the
continuity of the production tools and improve the quality of the products. In addition, the
installation had to comply with the ELV (Exposure Limit Value) regulations for the respiratory
tract and the latest amendments to the ATEX directive (2014).
.
AN INSTALLATION THAT EFFECTIVELY PROTECTS THE OPERATORS
WHILE GUARANTEEING A HIGH QUALITY PRODUCT
The first step was to offer full support in defining the need. These discussions
enabled the customer to be guided towards the most suitable dust removal
solution.
Once the solution had been selected, NEU-JKF Wood Industry installed a
compensated and regulated flow suction system. This system ensures an optimum
suction rate depending on the number of machines in use at the same time. The
centralized suction system is connected directly to the machines on the suction
outlets of the machine to protect the operators. On the other side the system is
connected to the dust collector.
The originality of the solution lies in the fact that the fan (high efficiency) which
ensures the suction is installed after the dust collector, thus placing the whole
system in a vacuum. As a result, the material no longer passes through the fan
wheel, which leads to better fan efficiency, less maintenance and energy savings.
The use of a standard, non-ATEX fan also means savings for the customer.
The waste is evacuated and stored in a 30m3 airtight container via a relay network.
From a regulatory point of view, this installation complies with the French Labour
Code (R4412-149), which imposes an exposure limit value (ELV) for the respiratory
tract of strictly less than 1mg/m3, as well as with the ATEX directives against the
risks of explosion. The external discharge is less than 10mg/m3 as required by the
standard.
