Not many engine manufacturers can meet the stringent technical requirements to produce a back-up generator for a nuclear power plant. Thanks to its robust and reliable design, Adria 40 engine has been the primary choice of many nuclear power plant owners around the globe when it comes to emergency power generation.

Adriadiesel is currently working on the refurbishment of Adria 40 engines for our dear clients in Russia.

Sulzer Type TD is built as a standard marine engine for direct propeller drive and suitable for all types of single-screw and multiple-screw vessels in river, lake, coastal and ocean service. The propeller thrust is transmitted directly to the thrust bearing built on to the engine through the transmission shafting.

Sulzer Type TG is chielfy used when the engine is connected to a reduction gear, a disengaging friction clutch or a flexible coupling (toothed coupling, Cardan joint, etc.), i.e. wherever the propeller thrust is taken by a thrust bearing in the gearing or behind the special coupling mentioned. For this reason, a thrust bearing built on to the engine is unnecessary. The engine type TD is thus mostly used for fishing boats (with reduction gearing), ferries, dredgers and other special-purpose vessels in which the propulsion arrangements are as described above.

Most wear and tear on Sulzer RTA models will occur on parts such as cylinder liners, cylinder head parts (valves, seats, nozzles), plunger and barrels. The bore size of the original RTA series has an extensive range of 380 to 840 mm.

We would like to inform you that we have MAN engines in stock as follows:

MAN 4 x 7L21/31 and 1 x 8L21/31.

These are brand new, unused engines manufactured under MAN license and the engines are available immediately.

We can offer two options, engine or diesel generator set (DGS):

Option 1) Engines + foundation (available immediately from the warehouse)

Option 2) DGS (includes engines, foundations and alternators; available within 4 months)

Most of the Sulzer A25 engines work in auxiliary power generators on ships, some as stationary power source and many as main propulsion in tugs, floating cranes, fishing ships and other workboats. Fuel type of A25 is MDO only.

Sulzer ZL40 is a favorable choice in main ship propulsion modules because its spare parts are widely available. Availability of spare parts reduces the cost and the duration of the execution of maintenance orders.

Sulzer S20 is a classic 4 stroke engine with number of cylinders ranging from 4 to 9. Sulzer made the journal diameters of this engine sizable to achieve high torsional rigidity. Additionally, S20 offers low operational costs due to easy maintenance and long maintenance intervals.

Using clean-burning fuels such as liquefied natural gas (LNG) are becoming more of an attractive option as they satisfy all emission requirements. Moreover, fluctuations in the fuel market make the plant owners reconsider their options when it comes to choosing the right fuel. Dual-fuel engines MAN 32/40DF, MAN 48/60DF, MAN L28/32DF, MAN L23/30DF, MAN L35/44DF, MAN 51/60DF, can simply switch between gas and liquid fuels which offer a great advantage when it comes to flattening the fuel expenditure curve and reducing emissions. The plant owners can additionally benefit from low operational and maintenance costs of these engines thanks to burning cleaner fuels which results in cleaner engine components.

A classic feature of Sulzer Z-type engines SULZER ZA, SULZER ZAS, SULZER Z40, SULZER ZA40, SULZER ZA40S is the rotating piston. This Sulzer patented concept with cylinder bores from 90 mm to 420 mm for highly loaded trunk piston engines has the following benefits:

-Even temperature distribution around the piston crown

-Minimum piston skirt deformation

-Optimum sealing and working conditions for the piston rings

-Low and stable lubricating oil consumption thanks to the small piston running clearances

-Smallest risk of seizure between the piston and the cylinder liner

After the production of the first SULZER 12 ZV 40/48 engine in 1976, production started on an upward trajectory and by the end of 1977, two more SULZER auxiliary engines with the designation 12 ZV 40/48 were produced. Production under the SULZER license has continued for many years and Adriadiesel is still one of the leading suppliers of spare parts for engine repairs.

"On December 28, 2009, the finished ZV 40/48 engine was loaded on the winch of the transport company Zagrebtrans, which delivered the engine to a destination in Russia. On January 4, 2010, the engine was shipped as desired. station in Karlovac where it was performed customs clearance and further dispatch. This 6th engine was ordered for the same customer, the Russian company Atomtechnoprom, but unlike the previous 5 which are delivered to Volgodonsk this goes to NPP Novovorenezh. Along with the engine, all the equipment of the plant was also ordered delivery is planned by the end of April, and a set of spare parts is being prepared. "

"Adriadiesel d.d. has launched the AD40 Automatic Engine Control System (ZL / ZV40). When running the system from 4.7. to 8.7. Mr. Alexei Remnev was here, a representative of the company ZAO "Science and Production company "Automated Systems" from Russia. The new system is made on the basis of modern microprocessor technology that ensures control of the motor code tests at the test station, monitoring, diagnostics of malfunctions of the engine and the system of the test station plant, registration and archiving of information and the possibility of printing engine parameters and storing them on a USB memory or notebook. This modernized engine management solution will greatly help our ADRIA 40 program to be of high quality
performed tests of the AD40 engine for Russian nuclear power plants."

"Negotiations / talks with our Russian partners about activation re-production of the 12ZV40 / 48 engine, our "bestseller" for the Russians nuclear power plants, started 3-4 years ago. And so the idea came to yes we start producing a similar engine, without a license relationship, like ours new own product - and finally the ADRIA 40, 12-cylinder 4- stroke diesel engine, V-version, power 6600 kW, 600 rpm.  And then in July last year, the first commercial contract was signed with Promenergokomplekt from Russia for delivery of 3 diesel generator sets ADRIA 40 for the Rostov 3 nuclear power plant. Delivery times were 12, 13 and 14 months, from the signing of the contract, we knew it was a little too ambitious, but we embarked on a project."

Internal newspaper "Adriadiesel" (2011.)

"A contract has been signed with the company Koridor, which represents the company Electrodynamics from Moscow, and related to the assessment of the condition engine 12 ZV 40/48 in NPP Kurskaya and NPP Smolenskaya. Execution of works is in progress. For Atomtechnoprom, we supervise the commissioning 12 ZV 40/48 in NPP Novovoronezh. "

n 2010, we started the project of revitalization of six Zgoda-Sulzer 6ZL40 / 48 diesel engines for the new 3rd and 4th units of the Mochovce nuclear power plant in Slovakia. During the second half of 2010 and the first half of 2011, the engines were completely revitalized at the Adriadiesel plants and shipped back to the Mochovce Nuclear Power Plant.

Adriadiesel manufactures its own auxiliary engine under its own license and design. The name of this engine is "Adria 40". In addition to production, it also sells spare parts and service services on its own engines. Adria 40 meets all the necessary standards and so far has proven to be a product you can rely on.

After the production of the first SULZER 12 ZV 40/48 engine in 1976, production started on an upward trajectory, and by the end of 1977, two more SULZER auxiliary engines with the designation 12 ZV 40/48 were produced.
