System descriptionWith the most achieved version of the system, we are able to transport sensitive or dangerous products. The MANUTUBE® is not a traditional belt conveyor; it is particularly powerful and respectful for the conveyed product, the operators and the environment in general. | ![]() |
It uses the principle of a conveyor belt running through an enclosed area where the product goes through a tube with a circular section and a return of the belt, without the product goes in a closed casing with a rectangular section, or inside an open casing made of welded steel plates and metal grids.
For the three models of MANUTUBE® conveyor (Classic, Select and control), the tube with a circular section in which the belt runs is fixed on the casing with a rectangular section.
On a « Classic » model, the return casing (belt without product) is an opened structure or with unsealed housing. It is a basic MANUTUBE® conveyor, the less sophisticated, designed for products which are not sensitive and do not need a perfect sealing.
In the case of « Select » and « Control », the tube with a circular section and the casing with a rectangular section on which it is fitted makes only one closed volume in which the belt, the conveyed product and the internal atmosphere . Internal atmosphere can be air or a controlled atmosphere (temperature, hygrometry, reduced oxygen content...), according to the product's requirements or security level of the zone where the MANUTUBE® conveyor is used.
The choice of materials, the inner atmosphere with inhibition of the oxygen by an inert gas (azoth, CO², etc.), and the earthling of the conductivity enables certifying the MANUTUBE® to ATEX conformity and, in some cases, to declassify an ATEX zone.
Except the remarkable advantage concerning security mentioned above (safety for operators, protection of the environment quality in general and stability of the conveyed product), the MANUTUBE® system offers other advantages developed below :
MANUTUBE® equipments are presents on the five continents in the following countries :
