The advanced seismic damper ensures a high standard of safety in the case of an emergency.

Even in the event of a disaster, two 1,750kVA emergency generators will provide power, ventilation, and sanitation for 72 hours at 100% quality as compared to ordinary times. By employing a hybrid damping structure that utilizes a combination of an unbonded brace and an oil damper, the vibrations of earthquakes of various magnitudes are reduced, ensuring a high standard of safety.
