Additional storage containers, transfer pumps and special kitchen taps can be installed adjacent to a distiller. Increased storage capacity will only be advantagous for continuous flow units. When the distiller's storage tank empties, it turns itself on and fills the storage containers. Distillers that use a combination of VOC removal methods are more efficient than one single method. Gas vents are small holes drilled into the passage leading to the cooling coils.
Gas vents allow VOCs to escape the distiller before they enter the cooling section coils.
VOCs are removed when they condense in a different section of the fractional column than where water does. Fractional distillers usually cost more than distillers with gas vents or ACF cartridges. An illustration of a reflux distiller. The ACF units are normally located at the end of the cooling coils and remove the VOCs prior to entering the distilled water storage container. ACFs can also be placed in the water supply line to reduce VOCs entering a distiller.
