Fire Protection for Power Generation

Modern society takes uninterrupted electricity supply for granted. All power plants deserve special attention to the fire protection measures to ensure business continuity at all conditions.

HI-FOG® water mist fire protection system scales from a single hazard protection to a total power plant protection. Several type approved system types ensure there is a cost efficient option for all power plant types. HI-FOG® offers an alternative to both gaseous and water based technologies to protect:

  • Gas turbines
  • Steam turbines
  • Diesel generators
  • Hydraulic systems
  • Transformers
  • Cable tunnels and spaces
  • Electrical rooms
  • Li-Ion Battery Energy Storage Systems (ESS)
  • Conveyor systems
  • Offices

HI-FOG® uses pure water to fight the fire, which makes it safe for the people and the environment. HI-FOG® is tested and type approved and provides superior fire protection performance with a small water quantity.
