An advanced technology, capable of offering maximum energy efficiency and characterized by high power available in peak conditions, as well as optimized performance at low and medium compressor speeds.

The compressor frequency increases constantly until it reaches the maximum level. This guarantees the absence of intensity peaks during the start-up phase and, furthermore, guarantees a safe connection to a single-phase power supply, even for high-power systems.
