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 latest EURO V emission standards.

Increased engine resource
Heavy Duty series generators can be used not only as emergency power source, but also for long-term full-time operation. The engine resource exceeds 3000 working hours, this is confirmed by multi-hour, multi-level tests and warranty. To show high performance, machines should be maintained properly.

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.

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.

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

AVR
“Könner & Söhnen” series diesel generators are equipped with intelligent voltage stabilization system AVR. It allows to keep the voltage at a constant value of 230 V and protects against unwanted short circuits.

Enforced frame
Additional frame reinforcement with the upper protective strips allows HEAVY DUTY professional series generators to operate in a more rigid mode. The reinforced frame structure protects the tank against damage during operation and transportation.

Dampers to lower vibration
All models of Könner & Söhnen generators are equipped with rubber feet to reduce vibrations. The working generator will not damage the floor covering, and the frame coating will not be scratched.

Accesories set
Generator is equipped with additional accessories:

• a portable 3Р+Е+N 16A 400V power plug
• a portable 2P+E 230V 32A power plug
• a 8x10mm hook key
• 12x14mm and 17x19mm keyholes
• a two way 6.0mm PH2 screwdriver

VTS system
Universal generators 2 in 1 with a unique phase switching system VTS (Voltage Transfer Switch), which allows you to use one generator as a single-phase (230V) and three-phase (400V) with almost no loss of power. Each mode has its own automatic protection. No need to buy two separate generators.

Automatic tranfer switch
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
