APPLICATION
FBC fan coolers/heaters make up a decentralised cooling/heating system. The air streaming through the heat exchanger is cooled/warmed up.
Fan coolers/heaters are used for cooling/heating large volume buildings: general, industrial and public buildings etc.
The casing of FBC fan coolers/heaters is made from extended polypropylene EPP.
Water droplet catcher and condensate tray are made of ABS plastic
The devices are designed for indoor use where maximum air dustiness does not exceed 0,3 g/m

. Units are built using copper, aluminum and
galvanized steel. It is prohibited to install units in corrosive environments. The devices can not be used in an environment where there is oil
mist.
Water heat exchanger could be supply by water or glycol solution up to 60%. The heat exchanger tubes are made of copper. The fluid
should not cause corrosion of this material. In particular, the parameters as below should be provided.
