Three-phase air dryers

Three-phase (400 V)

— connection to a three-phase 400 V power. Such mains allow to power very powerful devices, and also have a number of other advantages over single-phase 230 V — in particular, high load resistance and better accuracy in accounting for consumed energy. However, the very possibility of such a connection is much less common than in the case of 230 V — mainly at production facilities, in auxiliary premises, etc. So there are few dehumidifiers of this type produced, while such models usually belong to one of two types: heavy performant devices for which 230 V is no longer enough, or industrial models designed for installation together with other three-phase equipment in industrial premises, where 400-volt power supply is closest.
