This system is designed for customers in hot area, where the temperature is usually so high, even higher than the temperature in incubators. In this condition, high temperature air inside cannot be cooled by exchanging air with the outside.
For hatcheries that cannot control their temperature between 23~29degC, it is advised for them to install water cooling system. This system uses copper cooling pipes, which have a nice conduction capacity. The cooling water flow is controlled by the incubator controller. The customer shall prepare the cooling water, either from underground or supplied by chiller.
