Distillers allow us to purify drinking water through consecutive, controlled vaporization and cooling processes. These events allow separation of water molecules from other molecules or elements that are diluted.

Distiller maintenance operations will depend on the design and capacity of the equipment. In addition, the design will vary depending on the volumes of distilled water required in each facility. Regular maintenance of the distiller will allow us to have clean equipment, which works properly and will increase the life of the device.

When a distiller is installed in hard water locations, it can accumulate inlays in the boiling tank. If these inlays reach a considerable thickness, they promote the equipment overheating. Regular maintenance of the distiller, including cleaning, prevents the accumulation of inlays. For equipment designed to do so, it is recommended that the boiling tank be cleaned after each distillation.

Parts of a water distiller

In general, it can be said to consist of a steam generator or a boiling tank, immersion resistors, cooling water outlet, condenser, filter and distilled water tank.

The boiling tank is the tank where the water to be distilled is stored. It has the device that supplies the water to the reservoir, as well as controls over the level, flow rate and quality of the feed water.

Immersion resistors are devices that generate heat through electricity. They are coated with a ceramic layer and protected by a metal coating. The cooling water outlet, is the component of the distiller, which transfers the water used to condense the water vapor. The condenser is the device that allows the steam to cool down and return to the liquid phase.

The filter is located at the outlet of the condenser or collector and is used to remove flavors or particles from the condensed water. The tank of distilled water is the place where the water is collected after distillation.

Maintenance of the water distiller

As discussed above, the operation of maintenance depends on the design and capability of the equipment. In general, it can be said that there are different maintenance operations, which vary according to the frequency at which they are performed and the component of the equipment where they are performed. For example, it is recommended that the steam generator tank be inspected and cleaned monthly. While the operation for the change of the activated carbon filter is recommended to be carried out on a quarterly basis. In addition, the routine for cleaning the capacitor will be carried out at an annual frequency. Sterilization of the distilled water storage tank is occasional. The two most common maintenance operations are described below.

Maintenance of the steam generator or boiling tank

• We need to visually check the inner walls and immersion strengths for solids deposits. The quality of the water with which the distiller is supplied will affect the quantity of tanks present. If the accumulation of tanks is proven, we must clean to avoid damaging the immersion resistances.
• For cleaning accumulated tanks, it is necessary to use a chemical product designed for this purpose. Thereafter, the water in the boiling tank shall be drained to 10 cm above the level probe or immersion resistance to ensure that all elements of the boiling tank are immersed in the water.

• Add the recommended chemical and mix thoroughly.
• Allow the product to work overnight or as directed by the manufacturer.
• Stir the sediment within the time recommended by the chemical manufacturer.
• Drain the contents of the tank, add clean water, wash and drain again ensuring complete disposal of the removed mineral waste and chemical.
• Normal computer operation.

Activated carbon filter change

It is usually an easy component to replace. The process is as follows:

• Unscrew the filter cover and remove the used filter element.
• Install a new filter element, with the same features as the original.
• Reseat the filter cover.

Kalstein Distillers

In Kalstein, we offer a wide variety of YR series water distillers. You can choose the one that best suits your needs. The Kalstein water distillation equipment operates in an automated manner and is therefore easy to use. They are designed with a glass vessel on top, allowing observation of the distillation process. They promote water and energy savings and have a protection system for electrical overloads and, in addition, a protection function in cases where the water supply is reduced or interrupted.
