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.

How to protect yourself when purchasing?

If a washing machine is about to appear in your home, choosing according to the parameters that are important to you means purchasing the optimal piece of equipment.

How not to make a mistake in choosing?

It is better to choose an option equipped with security systems; The presence of special washing modes will help you save money on dry cleaning and wash things correctly, extending their service life; If the area of ​​the room in which the household appliance will be installed allows you, you should not buy narrow models

It is believed that in such parts the parts are located too close to each other, which is why they wear out faster; It is also important which company to choose a washing machine. There are manufacturers who have built up their reputation over the years and produce high-quality equipment

Examples of these are Samsung, Bosch, LG, Indesit, Gorenje, etc.; Despite the convenience and beautiful appearance of electronically controlled models, mechanical options are considered more practical and reliable, since they consist of fewer parts and their design is not complex; Buy household appliances only from trusted sellers - in stores or on websites that are well known to consumers and have many real positive reviews; Be sure to check the integrity of the case, surfaces, and completeness of the equipment when purchasing it.

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.

Optimal speed settings for different materials

Not all materials are subject to standard washing. For certain types of fabrics, a mode such as delicate washing will be required. As a rule, on modern models of washing machines you can set the required number of revolutions. Rotating the motor too quickly can damage some tissues.

Linen, jeans, cotton, calico

For denim and cotton fabrics, the permissible value is 800 rpm. It is also recommended to activate the delicate wash cycle. Linen is an extremely delicate material, so the spin cycle is either turned off or activated at a minimum number of revolutions.

Satin, silk

Satin, silk items, as well as tulle, must be washed at 600 rpm, since these are quite thin and delicate materials. If there is such a possibility, then the spin is turned off.

Wool

It is not recommended to wring out wool items. If this option is not available, it is recommended to set the minimum spin value (no more than 400 rpm).

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.

Tips for choosing a machine

For those who are planning to purchase a washing machine, we can advise the following:

1. If you intend to dry your clothes on a line, balcony or terrace, you should buy a machine with a low spin level.
2. If you are going to wash thicker clothes, such as jeans or wool, it is best to purchase a device with a higher spin rating.
3. Before buying equipment, you need to take measurements of the room in which you are going to install it and the place where the machine will be located . Based on this, the dimensions of the equipment are selected, as well as the type of loading.
4. You need to pay attention to the manufacturer. The quality and service life of this device, as well as the spin and washing class, largely depend on this, since these indicators may differ from each other.

Having taken note of the requirements that a high-quality washing machine must meet, you can safely go and buy it. After all, it is no longer possible to imagine the life of a modern housewife without this type of household appliance.
