Mitsubishi Diesel Generator ARK-M 2250 S5

ARK-M 2250 S5 Diesel Generator – Reliable 2250 kVA Standby Power with Mitsubishi S16R Technology

The ARK-M 2250 S5 diesel generator provides 2040 kVA prime and 2250 kVA standby power at 1500 rpm, powered by the Mitsubishi S16R-PTAW2 16-cylinder turbocharged and air-to-air cooled engine for maximum durability and fuel efficiency. Designed for intensive industrial environments, it delivers stable performance under high load thanks to its advanced cooling system, electronic governing, and robust filtration package. The system integrates a Stamford S7L1D-H4 alternator featuring Class H insulation, IP23 protection, ±1% AVR voltage accuracy, and THD below 5% for clean electrical output.
Equipped with an ARK700E control module with DSE compatibility, remote monitoring options, and extensive runtime statistics, the ARK-M 2250 S5 complies with ISO 9001:2015, CE, and ISO 8528 standards. This generator is engineered for mission-critical applications including heavy industry, data centers, hospitals, and large infrastructure requiring dependable high-capacity power.

ENGINE
Arken Jenerator provides industrial diesel engines that meet ISO 8528, ISO 3046 specifications; heavy duty type; oil, air or water-cooled depending on the requirements; 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 diesel 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 diesel protection. The diesel 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 Jenerator uses original European brand alternators for its gensets, that complies with all international certificates, IEC 60034-1, ISO8528-3, EN55011, 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
Arken Jenerator chooses its radiators from the original selection or from approved vendor list of its engine on boards for the purpose of usability, spare part availability, high performance and maximum efficiency. 55C remote type radiators are appliible.

FRAME
Arken Jenerator manufactures its own chassis based on international standards for all generator sets. The frames are designed and manufactured to provide high strength from the inside of the plate panel or profile to the vibration and stresses.

FUEL TANK
Arken Jenerator uses an in-chassis daily fuel tank in generator sets up to 800kVA. Larger power sets are supplied with an external stand-type fuel tank. Fuel tanks can be manufactured from plate steel or other suitable materials in accordance with the relevant standards. Arken fuel tanks mainly include:

  • Fuel fill point and cap

  • Tank vents

  • Fuel outlet valve

  • Fuel return connection

  • Tank drain plug

  • Sludge, etc. accumulation section

  • Transparent fuel level gauge

  • Floating level switch / Automatic Fill (Optional)

CANOPY
To provide sound isolation (ISO8528-10:1998) and to protect the generator from corrosive effects of external weather conditions, cabinets or containers are used depending on the size of the generator or the degree of sound intensity. Even low noise level is targeted principally, the cabins are designed in order to deliver stated power, in addition to the conditions set by ISO3046 and ISO8528, according to the tropical climate at 50C ambient temperatures, relative humidity of 30% at sea level is designed to deliver the declared power. Cabs come with a compact construction, low height, low sound level, easy access to the engine-alternator and control panel, lifting at two point , exhaust silencer stored in the cabin for safety and non-corrosion protection, and with ease of disassembly.

DOCUMENTATION
