The KS 33-3YE 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 liquid-cooled four-cylinder engine from the world-class engine maker YangDong. YangDong Co., Ltd. is the largest manufacturer of multi-cylinder diesel engines and supplier of high-tech products to more than 100 countries, combining flawless reliability and durability even in the most extreme operating conditions. YangDong Co., Ltd. maintains a strong presence in the European and U.S. markets, requiring unconditional compliance with applicable standards for reliability, fuel efficiency, environmental friendliness, and technical and operational safety of power plants, which best proves the high quality of products. The KS 33-3YE 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 75 l fuel tank offering a 15-hour autonomous operation without refueling (fuel consumption is 5.1 liters per hour at an average 50% load), connection for an automatic start/stop system, and an all-weather anti-vandal soundproof housing. 

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 high-performance KS 33-3YE diesel generator is a professional unit incorporating advanced technology but is also easy to use and can supply both three-phase and single-phase consumers. Protected power sockets and terminals for the external connection of power consumers add to the versatility of the diesel generator. 

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.


With its high quality and reliability, the modern YangDong 1500 RPM low-speed engine meets international standards and applicable regulations for fuel efficiency, environmental friendliness, and technical and operational safety.


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 a 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 high-quality 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. Anti-corrosion powder coating ensures a long service life of the unit.

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.


Könner & Söhnen KS 33-3YE diesel power station is a professional unit based on the latest generation of reliable YangDong engines featuring state-of-the-art technology and offering ease of use. The top-notch heavy-duty YangDong diesel engines comply with international standards and applicable regulations for reliability, fuel efficiency, environmental friendliness, and technical and operational safety. 

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.
