Capacity
The maximum amount of laundry that can be loaded into the dryer; in other words, the largest weight of laundry that the machine can efficiently process in one cycle.
Capacity is usually indicated by the weight of the dry laundry. Thanks to this, when preparing the laundry for washing, you can immediately assess whether it will fit in the dryer at a time or, on the contrary, you can get by with
a small drying. However, even the most modest modern dryers (and even
slim ones up to 50 cm) in most cases hold
7 kg — this is comparable to loading the drum of a medium-capacity washing machine. And in the most
capacious models, this figure can reach 10 – 11 kg. It is quite enough for domestic and even professional use (for example, in laundromats or laundries of hotels, etc.). However, the typical figures are
drying for 8 kg and
models for 9 kg of laundry. Bigger capacity is relevant for industrial equipment and is not found in consumer-level models.
Also, when choosing, note that in the specs the maximum capacity is usually indicated for linen made of cotton fabric. For other, more voluminous materials, the capacity can be noticeably less — for example, the weight limit for wool products is usually 4-5 times less than for cotton.
Drum volume
The internal volume of the dryer drum.
A
larger drum can accommodate more laundry, but there is no rigid dependence here: models with the same volume may differ in maximum load. It is because to process a large mass of laundry, one need not only a capacious drum but also an engine of appropriate power. At the same time, in a larger drum, the same mass of laundry will dry more efficiently than in a small one, because laundry will be more freely distributed over the drum, crumpled less, and warm air will better penetrate the folds of the fabric. As a result, for the same drum volume, a model with a smaller load will be more efficient and performant than a model with a larger load. On the other hand, a volumetric drum takes up more space and the dimensions of the dryer are largely determined by the dimensions of the drum.
Number of drying programmes
The number of preset drying programmes. Such programmes are often optimized for a specific type of fabric: linen, silk, synthetics, etc. The more drying programmes, the more versatile and easier the dryer is to use. However, a specific set of modes in different models may be different, and even a large variety of programmes does not guarantee that one of them will be suitable. So before buying, it is advisable to specify not only the quantity but the list of claimed programmes.
Steam drying
The presence of a
drying programme with steam in the dryer.
In this mode, the laundry in the drum is treated with hot steam. Note that this procedure is not suitable for drying as such; its purpose is rather to refresh and moisturize the fabric. For example, steam drying can be used as an alternative to washing when clean unwashed clothing has absorbed an unpleasant odour. It can be used to moisten overdried laundry for subsequent ironing.
Drum lighting
Lighting system for the internal volume of the device. It usually turns on automatically when the dryer door is opened - thus reducing the likelihood that some items (especially small and dark ones) will be forgotten in the drum.
Condensate tank volume
Only condenser dryers have such a tank (see "Drying type"). The larger the tank, the less often you have to get rid of the accumulated liquid. At the same time, in most models, the volume of the condensate tank is standard — about 5 – 6 litres: this is considered the best compromise between capacity and dimensions.
Energy class
The energy consumption class shows not the actual energy consumption but the efficiency of the dryer. In other words, what part of the electricity consumed goes directly to useful work. For dryers, this parameter is especially important because such devices have high electricity consumption. As a result, models with the same capabilities but different energy efficiency classes differ markedly in terms of operating costs (in terms of electricity bills). However, more economical units themselves are more expensive. nevertheless, this difference quickly pays off.
Initially, classes were marked in Latin letters from
A(the highest class) and further alphabetically. In the course of technology development, more economical levels of consumption than the original class A appeared — they are labelled as A+,
A++, A+++, etc. Actually, the highest efficiency class in modern dryers is exactly
A +++ ; level A —
A+ can be called good,
B — average, C — acceptable.
Noise level
The noise level generated by the dryer during operation. Usually, the specs indicate the maximum volume of the device, in the noisiest mode — when other programmes are running, this figure may be lower. We note that the noise level also depends on the features of the installation: for example, if the machine does not stand firmly on all four legs, vibration from drum rotation can create additional noise. And the tiled walls amplify the sound by creating an echo. Nevertheless, it is best to evaluate the device precisely by the noise level stated in the specifications. And here it is worth bearing in mind that the decibel used to denote loudness is a non-linear value, and it is best to evaluate the actual loudness of the unit using comparative tables. Here is the simplest such table for the volume range in which modern dryers operate:
65 dB — a person's voice in raised tones at a distance of 1 m;
70 dB — a loud conversation of several people at the same distance;
75 dB — loud laughter at a distance of 1 m;
80 dB — motorcycle engine, medium power vacuum cleaner.
The quieter the machine is, the more comfortable it will be to use and the better it will be suitable for a specific environment (for example, if there is a small child in the house or if you plan to run drying at night). At the same time, it is worth considering not only the actual noise level but also the installation location of the device. If the dryer is planned to...be installed in the basement of a private house with thick ceilings and the bedroom is located on the second floor, you can not pay much attention to the noise level: even the loudest unit is unlikely to create inconvenience.
Surge protection
It is a system that protects the dryer from power surges. Usually,
such protection includes the simplest voltage stabilizer capable of coping with relatively low-power short-term drops. If the capabilities of the stabilizer are not enough, the system completely disconnects the dryer from the mains and resumes power only when the voltage parameters return to normal. Usually, the current programme is remembered and, after switching on, continues from the same point where it stopped.
