The distillation process. Types of Distillation Equipment Distillers are commonly made of stainless steel, aluminum, and plastic materials. These materials do not absorb impurities from water and are easy to clean. The unit is turned on and the water is heated to boiling. When all the water in the boiling chamber is evaporated, the unit shuts off.
Distilled water is removed from the storage container for household use.
Batch units can range from 1gallon countertop units to 10gallon floor units. Batch distillers produce from 3 to 10 gallons of distilled water per day. The smallest distillers are about the same size as a coffee maker. The water level in the boiling chamber is maintained by a float valve connected to the water supply. As distilled water is removed from the storage tank, the unit turns itself on and starts producing more distilled water.
