Recuperators 400 V

Three-phase (400 V)

— power supply from a three-phase 400 V circuit is considered mainly the prerogative of powerful and high-consumption devices (including models with electric heaters), for which 230 V is not enough. However, relatively low-power ventilation units can also be produced for 400 V. This is due to the fact that connecting to a three-phase allows to achieve higher efficiency, reduce power surges in 230 V circuit nearby, and also more accurately calculate the amount of energy consumed. On the other hand, direct access to the 400 V is not available everywhere: for example, in residential premises it may be difficult.
