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.
Anti-crease function
This function of the dryer prevents the formation of the crease on the laundry as much as possible, which facilitates subsequent ironing. Of course,
anti-crease function does not give a full guarantee against creasing, but it noticeably makes life easier for the user. Especially when working with fabrics like linen or in cases where the things themselves are not particularly wrinkled but can crumple with inaccurate drying.
Refresh cycle
A programme designed to remove odours from clothes, such as tobacco smoke, or an unpleasant odour that appears after a long period of storage.
The refresh programme is useful if the clothes are clean, but the smell still needs to be eliminated — refreshing in the dryer takes less time and effort than quick washing and then drying (even if using the same dryer). This function is especially relevant for
drying cabinets.
Drain into sewer
This option allows you to automate the process of draining the condensate collection tank (respectively, it is relevant only for dryers with a condensation principle of operation). At the end of the drying process, the condensate accumulated in the tank is automatically drained into the sewer. To do this, a pump and a hose are provided in
a dryer with a drain into the sewer. The function of draining into the sewer allows you to significantly simplify the operation of the dryer, while in models without this option, the user must drain the condensate tank manually. Of course, manual emptying does not require much effort because the average condensate collection tank has a volume of about 5 litres, but still not very convenient.
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).
