High-performance optimally balanced V-twin water-cooled two-cylinders four-stroke engine (18 hp), which ensures reduced vibration of the generator during operation and it has the enlarged motor resource.

Increased engine resource


Universal generators 2 in 1 have a unique VTS (voltage Transfer Switch) phase switching system, which allows using a single generator both in single-phase mode (230V) and in three-phase mode (400V) with almost no loss of power. Each mode has its own circuit breaker. There is no need to use two separate generators.


Modern multifunction LED display shows frequency, voltage and operating hours of the generator. Displayed information makes it easy to determine the voltage generated by the device.

The ATS (Automatic transfer switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected.
Gasolineand diesel generators with an electric starter are equipped with a universal 5-pin connector for an automatic transfer switch unit (ATS input). The ATS unit has a PLC that allows the automatic start/stop of the generator to be programmed in the event of a power outage and after its restoration.PROGRAMMABLE LOGIC CONTROLLER OF THE ATS UNIT:
– Automatic/manual operation
– Programming of engine starting time after power outage
– Programming of engine warm-up time before connecting to consumer
– Setting of starter operation time
– Engine performance monitoring
– Battery charging when the generator is off

The generator is suitable for connecting the ATS (Automatic Transfer Switch) system.
The ATS (Automatic Transfer Switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected and automatically stops the generator when the central power supply is restored. ATS output has a 6-pin connection.

Preheater function

Preheater function

All Heavy Duty series generators are equipped with a preheat function, which allows you to easily start a generator in winter.


“Könner & Söhnen” generators are equipped with an enlarged steel fuel tank, which extends the generator’s operating time without refueling. The fuel level indicator is located on the tank for ease of use.

Increased warranty

Increased warranty

Heavy Duty series diesel generators have the extended warranty – 2 years or 3000 operating hours (whichever comes first) under condition of proper operation and scheduled maintenance.
