The KS 33-3DE-G three-phase diesel power station of the HEAVY DUTY series of the German brand “Könner & Söhnen” is a reliable generator set with a maximum capacity of 33 kVA. 

The power station features a low-speed liquid-cooled Deutz four-cylinder engine German company Deutz has a 150-year history of making diesel engines (including those for automotive and agricultural machinery), incorporating cutting-edge technologies and materials, high quality, reliability, failure-free performance and durability. Deutz engines demonstrate excellent performance in the most adverse conditions and can withstand maximum loads without compromising the service life. In addition, the KS 33-3DE-G diesel generator is equipped with a four-pole brushless AC alternator with an automatic voltage regulator, a preheater for use in the cold season, a 57 l fuel tank offering a 15-hour autonomous operation without refueling (fuel consumption is 3.7 liters per hour at an average 50% load), ), with possibility to connect an automatic start/stop system, and an all-weather anti-vandal soundproof housing with anti-corrosion coating. 

With the company's in-house developments and conformity to Könner & Söhnen requirements, all power stations have a margin of power against the declared specifications.

The powerful diesel generator KS 33-3DE-G is a professional unit developed using advanced technologies, while an easy-to-use device that can provide power for both three-phase and single-phase consumers. To ensure universality of use, the diesel generator is equipped with protected power sockets and power terminals for external connection of consumers.

Könner & Söhnen diesel generators accommodate all your needs for both emergency and standby power supply to ensure sustainable power supply to residential buildings and small commercial facilities.


The modern low-speed Deutz 1500 rpm engine provides optimal performance, has an increased service life for long-term use, as well as economical fuel consumption, making the German brand power stations one of the most cost-effective units.The electronic engine speed control system is a computer-assisted automatic engine speed controller that quickly responds to load changes, improves the quality of the electric power produced by the power station and guarantees the most stable frequency of 50 Hz.


The water-cooled engine system ensures reliable operation of the unit and prevents premature engine failure. The efficient cooling of the engine allows this generator set to be exposed to high ambient temperatures.


The engine preheater facilitates the start-up of the power station with no load on the engine, even in sub-zero temperatures during the cold season. The system automatically pre-heats the engine's water jacket to the required temperature and maintains the engine temperature to facilitate the engine start-up in any weather.


All operations are controlled via modern multifunctional digital controller. The controller provides monitoring of all operating indicators of the power station, convenient start-up and operation settings, monitoring of the battery status, engine speed and fuel supply adjusted to the load, and protection against overheating and low oil level. It also signals possible faults and reports the need for service maintenance. 


The top-notch soundproof housing provides significant noise reduction during unit operation, improves the thermal distribution and protects the power station against ingress of moisture and condensation, exposure to adverse weather conditions and tampering. Special galvanic coating adds to the wear resistance, durability, oxidation resistance and corrosion resistance, thus greatly extending the unit's service life.

In addition, the low-noise low-speed engines mounted on anti-vibration pads contribute to quieter operation and reduce the load on the base. 

The power station has an emergency stop button for quick engine shutdown in an emergency. 


The housing has openings for transportation aids, facilitating shipment, transportation, and installation of the unit.  Wide doors allow easy access to unit parts during maintenance.


For failure-free operation in Europe, Könner & Söhnen diesel power stations undergo pre-run servicing and a test run with monitoring of all operating parameters at our in-house service center. A special loading bench is used to check the power output of the power station in different operating conditions and to fine-tune the electronics control unit.


The Könner & Söhnen KS 33-3DE-G diesel power station is a professional unit based on the reliable Deutz engine with the best performance indicators. Reinforced parts and mechanisms, strengthened fasteners and joints reduce wear and tear and ensure long and reliable operation of the generator set.

Meticulously monitoring every stage of Könner & Söhnen production, we have created a series of high-quality and reliable HEAVY DUTY Silent Diesel Generators that will serve our customers for many years to come.

All Könner & Söhnen power stations undergo rigorous testing and guarantee high performance and maximum productivity.

**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 power station.
