ENGINE
Arken Generator provides industrial engines that meet ISO 8528, ISO 3046 specifications; heavy duty type, oil, air or water-cooled depending on the requirements; for low fuel consumption; with mechanical and/or electronical type of governor mounted on fuel pump to ensure precise speed adjustment and regulation; with oil, fuel and air filter system based on engine type; oil and fuel designed for heavy operational conditions in order to make sure the unit lasts a long time with high performance; 4-stroke; direct injection with all the limit and level sensors required for protection. The engine is supplied with all the necessary equipment for safe operation. Only engines designed for standby are not included in the production portfolio.

ALTERNATOR
Arken Generator uses original European brand alternators for its gensets, that complies with all international certificates, IEC 60034-1, ISO8528-3, EN50151, BS4999-5000 VDE 0530, depending on their power and requirements. The alternators, that has high efficiency and high performance for all conditions, have all the quality certificates and comply with world standards.
COOLING SYSTEM
In order to meet variations such as availability, ease of spare parts, high performance and maximum efficiency, Arken Generator selects its radiators from the original radiators of the engine company in the generator set or applies the radiators approved by the engine company to the generator sets.

FRAME
Arken Generator manufactures its own chassis for all generator sets based on international standards. The chassis are designed and manufactured from plate sheet or profile content to show high resistance to vibration and stresses.

FUEL SYSTEM
Pressure loss from gas mixer (mbar): 5
Maximum suction pressure (mbar): 30
Max. Gas inlet temperature (°C): 35
Min/Max customer supply pressure before gas regulator (Bar): 0.02 / 0.04
Min./Max supply pressure at motor inlet (mbar): 15 / 35
Min. diameter of gas inlet pipe (mm): 24

CANOPY
To provide sound insulation (ISO8528-10:1998) and to protect the generator from the corrosive effects of external weather conditions, cabins or containers are used depending on the size of the generator or the degree of sound intensity. Although the priority when designing the cabinets is aimed only at the sound level, in addition to the conditions specified by ISO3046 and ISO8528 standards, the generator is designed to provide the declared power in tropical climate and 50°C ambient temperature, 30% relative humidity value and sea level. The cabins have features such as compact structure, low height, low noise level, easy access to the engine-alternator and control panel, two-point lifting, exhaust silencer hidden inside the cabin for safety and corrosion protection, and the ability to be disassembled.
