Safety

  • For use in potentially explosive atmospheres, ATP/BTP submersible agitators are available in the "pressure-tight encapsulation" explosion protection category (Ex d) according to ATEX (zones 1 and 2)
  • Temperature monitoring in the motor winding
  • Monitoring of the seal system by "streisal Toplimiter" leakage probe in tandem version, i.e. with two mechanical seals and oil chamber on the inlet side
