Konner & Sohnen DUAL FUEL gas-petrol generators are currently the most popular among buyers due to their efficiency and environmental friendliness.
You can operate the generator on both gasoline and liquefied gas (propane-butane). Operating the generator on gas increases the engine's service life.
Everything necessary for connecting a gas cylinder is included: the generator is equipped with two reducers and a connection hose; you only need to connect the generator to the cylinder.
The generator is not designed for connection to a gas main.
If necessary, gas-petrol models can be easily switched to gasoline operation.
A powerful single-cylinder 4-stroke K&S air-cooled engine ensures stable and reliable generator operation. Gas is a more environmentally friendly fuel than gasoline.
Using gas as fuel results in fewer harmful exhaust emissions into the atmosphere. Each engine has an individual serial number, allowing us to control production quality and service. Konner & Sohnen engines are distinguished by easy starting and reduced vibration.
The KS 2900 series of gasoline generators is equipped with a reliable 1-cylinder engine with a power of 6.5 hp. Using gas as fuel significantly reduces your fuel costs when operating the device, and the price difference between a gasoline and a K&S DUAL FUEL hybrid generator quickly pays for itself. Can be used with both a portable gas cylinder and a stationary gas storage tank (gas holder).
Provided it is connected by a certified specialist.
The pressure in the supply system must not exceed 16 Bar. When operating on liquefied gas, the engine runs with less vibration, which contributes to long-term and stable generator operation and increases the engine's service life. Konner & Sohnen generators are equipped with a high-quality synchronous alternator with 100% copper winding.
Only copper winding can withstand maximum loads without any damage, guaranteeing long-term reliable operation of the generator set. The convenient ergonomic control panel of the generator allows you to easily start the generator and manage its operation, requiring no additional skills.
A modern intelligent LED display always shows the number of hours worked, frequency, and output voltage.
The information on the display allows you to monitor voltage, frequency, the number of hours the generator has worked, and perform timely maintenance, thereby extending its service life. Konner & Sohnen generators are equipped with an enlarged steel fuel tank, which extends the generator's operating time without refueling.
A fuel level indicator is located on the tank for ease of use. All Konner & Sohnen generator models are equipped with a dual anti-vibration system, which reduces noise and extends generator operation.
The engines are mounted on high-quality rubber cushions.
The reinforced steel frame has rubber supports for additional vibration reduction, anti-slip, and corrosion protection.
