SKU KS333XM Categories

The KS 33-3XM 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 Xinchai four-cylinder engine.

Xinchai Co. Ltd is a world-renowned manufacturer of multi-cylinder diesel engines (including those for construction and agricultural machinery) with more than 40 years of experience in design and production. Xinchai’s high-tech manufacturing enjoys impeccable market orientation and develops engines with more efficient parameters, lower fuel consumption and lower emissions. The KS 33-3XM 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 4.9 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 33-3XM 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.

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 Xinchai 1500 RPM low-speed engine is the best cost-effective solution designed with the latest technology using the most advanced equipment. The cost-effective engine provides optimum performance and has a long service life for sustained use. A mechanical engine speed control unit adjusts the engine speed and controls the quality of the electrical power produced by the generator.


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. The relatively compact size of the power station provides more space for its placement. Anti-corrosion powder coating contributes to a longer 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 hinged doors on both sides of the housing provide unobstructed access to the unit parts for easy servicing of the main components of the diesel generator.


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 33-3XM diesel power station is a high-end unit based on the world-renowned Xinchai engine with superior performance, reduced fuel consumption and lower emissions. 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.
