There are three principal parts, a refrigerator or evaporator, a compression pump, and a condenser.
The modern distilling plant consists of two main parts termed the evaporator and condenser; in addition there must be a boiler (sometimes steam is run off the main boilers, but this practice has several disadvantages), pumps for circulating cold water in the condenser and for supplying salt water to the evaporator, and a filter through which the aerated water passes.
The evaporator Viii.
The water vaporizes and is led from the dome of the evaporator to the head of the condenser.
The water level is maintained in the evaporator until it contains a certain amount of salt.
