(FOR NUCLEAR POWER PLANT)
HI AIR KOREA SMOKE DAMPERS for nuclear power plant can be installed at HVAC systems provided for various buildings of a nuclear power plant.
HAK SMOKE DAMPERS are used to prevent the spread of smoke from the space of fire origin to other spaces in the same building.
These dampers are available as safety related (SR) and non-safety related (NSR) items. Safety related dampers are fabricated with Q class components & dedicated commercial grade items, and verified for seismic qualification (SQ).
If necessary, they can be verified for environmental qualification (EQ).
