Dehumidifiers with anti-freeze mode

Anti-freeze mode

— a function that prevents excessive cooling of the dehumidifier parts and the formation of a large amount of ice on them.

Recall that all modern dehumidifiers (except for adsorption ones, see "Suitable for") have refrigeration systems — to remove excess heat generated during moisture concentration. In some cases, individual components of such systems can cool down strongly (down to sub-zero temperatures), which is undesirable both in itself and due to the formation of ice. To avoid this, the anti-freeze system constantly monitors the state of the evaporator and, if necessary, turns on the heating, preventing a critical drop in temperature and removing the ice that has formed.
