Spin efficiency class of washing machines - Which class is better

When purchasing a washing machine, you need to carefully familiarize yourself with its parameters and functionality. It is recommended to pay special attention to electricity consumption, spin efficiency class and other indicators that ensure normal operation of the unit.

What is a spin class

The spin class refers to one of the important performance indicators of the device. Its essence lies in the speed of the drum, at what speed it rotates, on which the final moisture content of the washed laundry will directly depend.

To determine this indicator, there are calculations and tests carried out at the production stage of the machine. Weighing of items before washing and at the end of the work process. Next, the first digit is divided by the second, as a result of which the required coefficient is derived, which determines the spin rate.

Principles of classification

The efficiency of moisture removal is related to the number of revolutions made by the drum. In modern products this parameter is in the range of 700-1700 for 1 minute. The final result determines the degree of dryness of the washed laundry at the end of the process, which takes into account the residual amount of moisture.

In practice, this indicator can be calculated as follows:

• The wrung out laundry is weighed.
• Next, things are dried.
• Re-weighing is performed.
• A lot of dry clothes are subtracted from the weight of wet laundry.

The data obtained must be divided by the weight of the items after drying and multiplied by 100. For example, you can take 6 kg of laundry after washing. Dried laundry already weighs 4 kg. Next, 6-4 = 2. The number 2 must be divided by 4, you get 0.5. After multiplying by 100, it comes out to 50%. This will be the parameter for the efficiency of moisture removal.

Types of spin classes

Explanation and characteristics

The calculation method given above allows you to accurately determine the spin rate even in a normal home environment and compare whether it coincides with that declared by the manufacturer. In this case, you should take into account the speed at which the drum rotates. The higher this indicator, the less moisture will be present in the dried laundry.

Knowing what the spin class is in washing machines, you can easily determine which is better and make the appropriate choice.

What do European indices say?

Therefore, the spin class is essentially a certain percentage of moisture remaining in clothes and objects after washing. Manufacturers performed all the necessary calculations in advance and derived so-called European indices that reflect a particular class. To designate them, Latin symbols from A to G are used. Each of them has its own meaning and accurately indicates the degree of dryness of the laundry at the end of washing.

International classification

According to the classification adopted in other countries, the efficiency or spin speed directly depends on the speed of a particular model. For example, with indicator G, the percentage of humidity will be more than 90, since the revolutions here are only 400 per minute. Class F already has 600 rpm and the humidity will already be 80-90%.

The best performance is in classes A and B. In the first case, the speed is 1600-1700, and the amount of moisture is less than 45%. In the second option, the rotation speed is 1400, and the humidity percentage is from 45 to 54. These parameters are indicated in the labeling of the unit, and they should be taken into account during the purchase.

Dryer and iron in one drum

When choosing a particular washing unit, you should take into account other, no less useful, additional parameters. One of them is the spin mode in the washing machine, at the end of which things are slightly ironed and become less wrinkled.

A similar effect is achieved by periodically changing the speed of rotation of the drum. As a result, the laundry wrinkles much less and after washing it looks almost ironed. All that remains is to hang them up for final drying.

A washing machine with clothes dryer is a very convenient function, and you should definitely ask the seller about it, so that in the future the laundry comes out of the machine not only clean, but also as dry and wrinkle-free as possible.

Why technology research is so important

Most domestic consumers are focused on low prices. By this I mean all kinds of promotions and discounts. You won’t believe how many people came to my store and chose something other than what they originally wanted, because of a limited budget or because they were not mentally ready to spend a little more money on this or that equipment.

I’m not saying that only a high price is an indicator of quality, but no one will give away a reliable thing for cheap.

There are high-quality fakes. Why are they cheaper? Firstly, because they do not have the warranty provided by the original manufacturer. Secondly, the one who copies will not spend money on in-depth professional testing. And this point greatly affects the efficiency of the equipment and its service life. The conclusion is that a good copy can serve you just as well as the original, but for much less.

Promotions for new original equipment are carried out in two cases:

• the real price is too high, and the magic word “discount” attracts buyers like a magnet;
• During the research, it turned out that the model does not correspond to the declared class, and the money for its development was spent as if it were a high-class device. The manufacturer can label it at a lower level and sell it a little cheaper.

Relationship between spin class and energy consumption

Electricity consumption is considered the most important factor when choosing a washing machine. After all, the cost of maintaining and operating the washing machine depends on this parameter. However, you will have to put up with excessive electricity consumption if you want to get the most dry laundry possible. That is, an increased spin class of washing machines is associated with increased energy consumption.

To date, additional subclasses have been developed, for example, A+, A++, A+++. They do not depend on the spin classification, but only indicate the efficiency of the model in question. In any case, the most efficient and productive machine not only becomes more expensive in itself, but its operation will also be expensive. If future costs are not scary, you can safely choose units with high performance indicators.

Looking for pros and cons

All washing machines have their own advantages and disadvantages. Thus, A-class devices provide clean laundry in virtually dry form. They are best suited for organizing heavy, bulky items. If the spin is of poor quality, things will weigh a lot, which causes difficulties and inconvenience in hanging them. For some people, such loads are generally contraindicated. In such cases, you should not save, but buy a machine with a full range of functions. And wet laundry will dry much faster.

However, the economic component must be taken into account. During subsequent washes, the machine spinning intensively will consume a significant amount of electricity. Therefore, you should choose carefully, paying special attention to modern, economical products with subclasses A with pluses.

Most consumers opt for units of class B and C. Their moderate speeds will not spoil woolen or silk products. The mechanical wear of such things is noticeably reduced.

How to choose?

Everything is clear with the washing class: the higher it is, the better the machine washes. Push-ups are more difficult. It is useful to know the following nuances:

1. Level "A" is rare.
2. The higher the push-up degree, the more expensive the model.
3. Not all fabrics can be wrung out too much. Thus, wool and silk can be damaged.

So is it necessary to overpay for the indicator in question? Things will still dry out. And if drying takes place on the street, balcony or loggia, then it will be completely free. For normal operation, it is enough to select spin class C or D. The items removed from such a machine are damp, but water does not drip from them, and it only takes a few hours to dry them naturally. Versions F and G - low push-up efficiency, not worth taking.

It should be understood: a high speed of rotation does not mean a high class of spin efficiency. The speed is not the only parameter that affects the dryness of the laundry removed from the drum. Of course, there is a dependence, but it is not direct. Of course, a device with a maximum of 500 revolutions will not be able to squeeze things to a humidity of 40%. But modifications with 1000 revolutions can squeeze laundry at efficiency levels B and C. 1000 revolutions will give about 65% humidity. This is the best option.

Speeds of 1600–1800 rpm are used extremely rarely, and you should not chase models with similar parameters. If we compare the speeds of 400 and 800 revolutions, the differences are significant - 90 and 75% moisture, respectively.
