Certified draft tube mixer systems are operated in ex-zones. According to the high technical demands, our operating and maintenance requirements recommend scheduling a general inspection of the system after 60,000 to 80,000 operating hours. These overhaul measures ensure the system works over the next maintenance interval.
Just ask us about the particulars.
We retrofit existing systems, so they are conforming to ATEX. The mixer will be equipped with the required monitoring systems of the latest state of the art and then, it is re-commissioned according to the effective ATEX (2014/34/EU).
TMA draft tube mixers from Träxler are ATEX-approved: Model Ex II 1G c/II 2G c T3, Certification No. TÜV 05 ATEX 7157 X. They are conforming to Directive 2014/34/EU for mechanical Ex-protection and they are type examined up to ATEX zone 0. This zone contains continuously or frequently an explosive atmosphere and requires increased safety. All measures for production, repair and installations are audited and certified annually by the TÜV.
Our construction department checks the design specifications and it calculates the natural frequency of the existing shaft in order to ensure specifically that the system runs smoothly.
Just like any other technical system, it is possible that the operation of the draft tube mixer malfunctions. Hermann Träxler is equipped for such events and it also helps in this case. Don't hesitate to talk to us.
