Alternators

3 phase alternator system


Main features


Efficient and fuel-saving energy production by modern truck engines

One alternator supplies the energy for a truck-trailer unit.

Large speed range. No turning off in idle or at high speeds.

Over 30 years experience in alternator drive systems and fitting by leading truck manufacturers on their own production line.

Highest efficiencies thanks to very large copper coil and core sections

High temperature resistant winding, vibration and moisture protected.

Long life

Splashwater protected aluminium housing. No entry of dirt in the bearings.

Compact size, simple installation, low weight.

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.

Specifications are subject to change
Because of the market position of the alternator driven FRIGOBLOCK refrigeration machines, well-known truck manufacturers already take into account the technical requirements for the installation of FRIGOBLOCK alternators during the development of a new truck series with gross combination weight rating of 7.5 tons and above.
