The Swedish company Alfa Laval is a world leader in key areas of heat transfer, separation and fluid handling technologies for many industries, including shipbuilding and marine energy. Today it is already an international industrial concern, which has 28 large factories around the world, 15 of them in Europe, 8 in Asia, 4 in the USA and 1 in Latin America, as well as 70 service centers. Scientific developments are carried out in 20 research centers. 110 commercial units and representative offices in 95 countries successfully sell Alfa Laval products.
It all started with the development by Gustav de Laval of a centrifugal milk separator with a capacity of 130 liters per hour, first demonstrated in 1879 in Stockholm. Alfa Laval's founding year is 1883, when Gustaf de Laval and his partner Oskar Lamm formed AB Separator.
The most important stage in the improvement of separators is the acquisition of a patent for conical metal discs from the German inventor Clemens von Bechtolsheim in 1889. With the help of these so-called Alpha discs, the performance of the separator has increased many times over.
Alfa Laval sold the first oil separator in 1916. In the prewar years, enterprises were formed in Denmark, South Africa, Finland, Australia, New Zealand, Poland, Yugoslavia and Ireland.
The company's first sales of self-cleaning separators begin in 1951.
In 1963 the company changes its name from AB Separator to Alfa-Laval AB. The name “Alfa” is derived from Alfa disks and “Laval” from the name of the founder of the company.
In subsequent years, the company has successfully developed in the areas of heating, cooling, separation (separation) and transportation of liquids in enterprises engaged in the production of food products, beverages, chemicals and petroleum products, medicines, starch, sugar, ethyl alcohol, etc. In addition, the company produces refrigeration and air conditioning equipment. Alfa Laval is expanding its factories, offices and warehouses around the world.
In 1993, the corporation acquired the Bolshevsky Machine-Building Plant (Korolev, Moscow Region), later renamed Alfa Laval Potok OJSC. Now the plant has two production facilities: collapsible plate heat exchangers and air heat exchangers for refrigeration systems.
Alfa Laval has now become the world's leading supplier of separators, heat exchangers, pumps, refrigeration and air conditioning equipment, both through in-house developments and through the acquisition of patents, as well as the acquisition of other companies such as Helpman, Finnish Fincoil, Packinox SA, Aalborg Industries , Frank Mohn and others. All this has led to a significant strengthening of Alfa Laval's presence in the offshore and offshore markets.

In the modern navy, ships are equipped with powerful power plants that use heavy residual fuel grades. This makes it necessary to prepare the fuel for combustion in the engine in order to ensure its long and trouble-free operation. The key to a long engine life is a high degree of fuel and oil cleaning efficiency. The main mechanism of fuel preparation or oil cleaning systems, the separator, is responsible for this task. The centrifugal separator separates foreign mechanical impurities and water from fuel or oil and removes them using the difference in the density of the components and the centrifugal forces generated during the rotation of the separator drum. Water and particles of higher density under the action of centrifugal force accumulate near the outer wall of the drum during the separation process. The accumulated sludge is ejected through the outlet openings of the separator in self-discharging separators or removed mechanically when cleaning the separator in non-discharging ones. Similar devices are available on every ship and may differ in design, but rarely differ in functionality.
The company "Norta MIT" brings to your attention the products of the best manufacturers in this area, such as ALFA-LAVAL , WESTFALIA , MITSUBISHI and other companies.
Scandinavian quality in every detail
The most commonly used separators in the fleet are alfa laval. In separators of this company, the interplate gap is reduced by 17-22% compared to other companies. Due to this, it was possible to increase the number of plates in the drum without increasing its dimensions. A standout design element of these models is the presence of specific pressure discs that serve as a replacement for traditional pumps for pumping fuel and oil. The company pays much attention to the automation of the separation process. For example, the Alfax and Alcap technologies developed by the company ensure the operation of alfa laval separators in automatic mode, performing all work operations according to a predetermined program. Alarms and protection are also provided. The partial discharge method used in the new alfa laval separators has reduced fuel or oil losses, water consumption and maintenance costs. Alfa Laval is constantly improving its products. In the field of shipbuilding and ship repair, the new development of the company is the separation systems of the S and P Flex series. The alfa laval type S separator complies with CWA 15 375 (Performance Standard for Marine Separation Systems) It uses Alcap technology. The system parameters are adjusted automatically depending on the density of the heavy fuel. The alfa laval type P separator does not use Alcap technology. The selection of the gravity disk depending on the density of heavy fuel is carried out manually. This economical option is used to separate diesel fuel and lubricating oil of uniform density. Control automation is carried out using the EPC 60 modular control unit, which is protected from vibration and high engine room temperature.
With German precision especially for you
Another well-known representative of this class of machines is the westfalia separator. GEA Westfalia Separator supplies separation systems specially designed for continuous operation under the harshest conditions. This provides you with:
Optimum performance
Long service life of your engines
High environmental standards
westfalia self-dumping separators with UNITROL systems automatically control the water level in the oil product during the round-the-clock cleaning of solid contaminants. The result is optimum separation efficiency for various types of fuels and lubricating oils. Maintenance is generally required only after 8,000–16,000 hours of operation. The operation, which does not require operator control, greatly facilitates the work of the machine team. The collected oil sludge can be processed on board, which will significantly reduce waste disposal costs. All separation systems can be supplied as separate modules. The new westfalia "eagleclass" separator class has been developed using the know-how of the technology leader in centrifugal separation processes. The innovative separator design and the new Westfalia Separator® unitrolplus control system set new standards in the energy, offshore, oil and gas, industrial and environmental technology market segments. Large centrifugal forces made it possible for the first time to reach a capacity of 80 m3/h. The Westfalia Separator® unitrolplus guarantees maximum separation efficiency for various liquids such as fuel, lubricating oil, oiled water, detergent liquor, etc.
Westfalia separators are time and sea proven units ready to work in the toughest conditions.
In addition to the supply of complete separators, Norta MIT offers spare parts for separators, both new models and separators that have been in operation for quite some time. Send a request to our office by E-mail, or directly from the site, and our managers will help you choose the separator or spare parts for separators you need.
