Core Technology

Puts out the fire,
takes out the heat

We were the first in Korea to develop a cooling and fire suppression system based on fluoroketone (FK-5-1-12). If a server rack catches fire, the system extinguishes it early while keeping heat in check. The work is covered by seven core patents and earned a commendation from the Minister of SMEs and Startups.
