CONTROL DAMPER
(FOR NUCLEAR POWER PLANT)

HI AIR KOREA CONTROL DAMPERS for nuclear power plant can be installed at HVAC systems provided for various buildings of a nuclear power plant.

HAK CONTROL DAMPERS are used to regulate the airflow rates automatically to ensure the required condition of plant.

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).
