Housing modifications reduce risks and improve operation

  • BRUSH Service can carry out a Positive Pressure Vent Modification (PPVM) to your existing exciter housing which has been proven to significantly reduce the rate of dirt contamination and mitigate the potential hazard of hydrogen ingress.
  • Housings are modified so the inside pressure is at a higher level than the outside, which reduces the intake of dirt and contamination during operation.
