EHC Filtration

WJZ-K8 EHC Filtration Unit

The WJZ-K8 EHC Filtration Unit is specifically designed for fire-resistant oil (EHC fluid) treatment using proprietary WMR membrane technology. With a dew point reaching -40°C, this unit prevents air-born contaminants from entering the system and keeps fire-resistant oil moisture content below 150 PPM, ensuring safe and reliable operation of electro-hydraulic control systems in power plants.

Key Benefits

  • Prevents air contaminants from entering system
  • Keeps fire-resistant oil below 150 PPM moisture
  • Reduces acid number effectively
  • Low maintenance requirements
  • WMR membrane technology with -40°C dew point
