High-end models of HEAVY DUTY SILENT series diesel generators in a soundproof anti-vandal housing. Thanks to their robust housing, generators have reduced noise levels, additional protection from all weather conditions, dust and dirt. Like other generators of HEAVY DUTY series, these models feature increased service life (more than 3000 operating hours), pre-start heating of fuel mixture, as well as a unique VTS phase switching system.

Könner & Söhnen engines

Engines for both diesel and gasoline generators are manufactured under the license of DIMAX Int. GmbH and are marked with K&S logo. High power of engines in relation to the alternator allows to receive the declared power output and maintain stable work at any load. All engines are tested for continuous operation, and then disassembled and examined for trouble-shooting purposes. Each engine and each generator have an individual serial number, which allows us to control the quality of production and service. The engines meet all European quality standards, including the level of harmful emissions and noise level.


All-season soundproof antivandal housing provides effective protection for the generator and extends its service life. The housing is equipped with handles and casters for easy handling.

Super Silent

Super Silent generators (with maximum power for a one-cylinder engine) have an advanced noise reduction system thanks to the double muffler, which provides a minimum noise level Lpa (7m) of 64 dB even at maximum loads. With a two-chamber housing design, these models have improved thermal distribution inside, which significantly extends their service life.

Ergonomic control panel

Convenient and ergonomic generator's control panel allows you to control the entire unit easily and does not require additional skills. The modern intelligent LED display will always indicate the number of hours worked, frequency and voltage output. The information on the display helps to control the device load and timely maintain the generator, extending the operation life.

The ATS (Automatic transfer switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected.

Gasoline and diesel generators with an electric starter are equipped with a universal 6-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.

– 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 KS ATS 4/63HD ATS unit is compatible with all Könner & Söhnen diesel generators with the abbreviation “ATSR” in the article number.

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.


HEAVY DUTY series generators are equipped with a fuel mixture preheater which is especially necessary for startup during the cold season.

Transport kit

Generator housing is equipped with a 4 wheels transport kit for convenient unit movement.

**In transient modes, the frequency of the generator can change in the short term, that is, during normal operation of the generator, the deviation of the frequency indicator is permissible. Depending on the type of generator, engine and operating mode, the frequency can be 49-54Hz

***Fuel consumption depends on many factors, such as load, fuel quality, season, altitude, technical condition of the generator.
