3-phase alternator systems
Already in the early 1970s, FRIGOBLOCK decided on the development of the alternator drive system in which a powerful 3-phase alternator produces up to 40 kW electrical energy for all electric FRIGOBLOCK refrigeration machines.
The FRIGOBLOCK 3-phase alternator produces 230/400 V and 50 Hz, i.e., the same voltage and frequency as the European power supply system. This means that there is no problem to run FRIGOBLOCK machines on a mains supply without the need of any additional equipment.
