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.
Inverter motor
The presence
of an inverter motor in the design of the dryer.
An inverter motor is a motor whose power and speed can be smoothly and accurately adjusted — in contrast to a conventional electric motor, in which adjustments are made in steps. However, the main advantages of machines with this function are low energy consumption and noise level. In addition, inverter motors have relatively few moving parts, which has a positive effect on reliability and durability. Their disadvantages are high price and difficulty in repair.
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.
Drying basket
The presence
of a drying basket allows you to carefully place woollen items, as well as shoes, which contributes to delicate drying and the laundry does not “fly” around the drum like in washing machines.
Self-cleaning heat exchanger
System
for automatic cleaning of the heat exchanger from fibres and all kinds of deposits that prevent easy air circulation. The self-cleaning function is performed during each drying cycle. It extends the life span of the heat exchanger and ensures consistently low energy consumption over the life span of the dryer.
Condensate tank indicator
It is an indicator signalling the filling of the tank with condensate and the need to empty it. It is used exclusively in models with a condensing type of drying (see above). The specific device and functionality of the indicator may be different: in some models, it only warns of a critical liquid level. In others, it can display the exact amount of condensate collected. However, this feature greatly simplifies the monitoring of the operation of the dryer and reduces the risk of flood and other troubles that can lead to an overflow of the tank.
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.
Drying class
Drying class describes the overall drying efficiency that the machine provides. It is denoted by a Latin letter, where A is the best efficiency, and further in decreasing order (
drying class B is inferior to
class A, but exceeds
class C). Naturally, higher efficiency machines cost more (ceteris paribus).
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.
