Our client in the pharmaceutical sector needed a conveyor to extract chemical powder from a tank in a closed room with a nitrogen stream inertisation system. The machine needed to be ATEX Zone 1/21 certified and approved for this type of location.
Other requirements were a flow rate of 3m3/h and an inclination of 29º. The main difficulty of this project was the working conditions in a highly explosive area.
SINFIMASA has designed and manufactured a TS-150/170 screw conveyor model 3.470 mm length between inlet and outlet with ATEX certification, all in 316L stainless steel (trough, cover and screw), finished in satin polish. The conveyor is equipped with a 3 kW SEW gear motor.
Sinfimasa has carried out the following markings:
- Ex II 2 G Ex h IIB T3 Gb (zone 1 - GAS)
- Ex II 2 D Ex h IIIC T160ºC Db (zone 21 - DUST)
These will be send with the documentation of use and warnings in the language of the country of destination.
