This type of industrial dehumidifier has a heat pump that generates a hot and cold zone. The cold zone is used to condense the humidity to remove it from the air, while the hot zone is used to return the air to the outside at a suitable temperature.
So, the process starts when an air stream is drawn in and passed through the evaporator (cold zone), where the moisture condenses and falls into the receiver. Then, the air reaches the condenser (hot zone), where it recovers the ambient temperature and is expelled to the outside.
