Dishwasher type: condensing, intensive, turbo dryer

In home appliance stores, customers are often asked questions: which type of dishwasher is better? Different models usually have one of three types of drying:

condensing;
intensive;
turbo.

Depending on that, what the buyer values most: speed, saving electricity or new technologies, one or another drying class will suit him, used in the dishwasher. Let's try to understand in more detail, what are the advantages and disadvantages of each.

Condensation type of drying

Condensing dryer in the dishwasher has been used for a long time. This type was used in the first models of dishwashers with drying due to the simplest mechanism of action. The condensation process occurs as follows:

At the very last stage of the washing program, clean dishes are covered with boiling water.
The resulting vapors settle on the upper cold walls of the machine. There they condense back into water droplets.
Drying of ware proceeds in conditions, close to natural.

As a result, the process of evaporation of moisture is quite slow, and on the dried dishes then often visible traces. Meanwhile, models of condensing dishwashers have a lower price compared to others. Another advantage is their low energy consumption.

Turbo drying mode

The device of dishwashers with drying in the turbo mode differs in bigger complexity. In addition to the usual parts, they have a heater for hot air production and a fan for blowing wet dishes. Turbo drying proceeds as follows:

TEN and fan, which are in a chamber protected from moisture, provide a continuous supply of hot air.
This stream of air continuously blows on wet dishes and dries it.

It is not difficult to guess, that dishwasher, equipped with a turbo dryer, much faster copes with the task: the model is good for those, who wants a quick result. However, you will have to pay much more for such equipment, than for the model with a capacitor, and it will shake the electrician harder.

The design of the dryer has additional spare parts, required for the production of hot blowers, therefore, the probability of failure of one of them is high. If the heater burns out or the fan breaks, the dishwasher will not dry the dishes due to the violation of the optimal temperature regime.

Intensive heat exchange drying mode

To make dishwashers a little cheaper, manufacturers have decided to use the laws of physics of heat transfer processes for the drying process in some models. This is how machines with an intensive type of drying appeared. The principle of their work is as follows:

Water enters the cold chamber of the reservoir, and air enters the adjacent chamber through special openings.
Due to the temperature difference between the reservoir and the walls of the cabinet there is a pressure difference, which causes incoming air to circulate.
Intense air movement dries moisture on the dishes.

So, in the dishwasher with the heat exchanger there is no heating element and the fan. Advanced device, appeared relatively recently, allowed not only to reduce the cost of the device, but also to achieve, so that it consumes as little electricity as possible.

In addition to types of drying in dishwashers, there are also their classes. The letters "A" and "B" can often be found in the description of the characteristics of dishwashers. Drying of the highest class "A" provides completely dry ware, class "B" implies the presence of some moisture.

And very often the dishwasher does not dry the dishes due to improper loading or overloading the cabinet. That the device lasted long, did not break and coped well with its functions, simple rules of its operation should be followed.
