In Suwon City, Korea, Frico radiant heaters SZ are mounted in the ceiling. Heating with radiant heaters is indirect.
The heat is transferred from the radiant heaters at the ceiling to surfaces as the floor. This means that the radiant heaters create a very equal temperature distribution between floor and ceiling.In a gymnasium as this one in Suwon City, placing the heaters high up also provides a more safe installation. Installed lower, they would be more exposed to damages caused by spectators, sportsmen or sport equipment.
The gymnasium in Suwon City hosted the handball games during the Olympics in 1988. If the Olympics where to be held there today, the 1188 meters of SZ would ensure the right temperature throughout the premises.
