Heat exchangers Alfa Laval

The company is a leader in the field of heat transfer in the world market.

Heat exchangers Alfa Laval- equipment designed for modern cold rooms, heating systems and hot water supply circuits, ventilation and air conditioning systems. For more than 100 years, heat exchangers of the Swedish concern Alfa laval are of the highest quality workmanship. Founded in 1883, the company Alfa laval today it is a recognized leader producing heat exchange products of the highest quality in more than a hundred countries around the world.

In Russia Alfa laval appeared in 1992, opening its own manufacture of heat exchangers in the Moscow city of Korolev on the basis of a former machine-building plant. Now the company Alfa Laval Is the only enterprise with a full cycle of production for manufacturing plate heat exchange equipment on a large industrial scale - from the manufacture of seals and plates to the assembly and testing of heat exchangers. As an international corporation, Alfa Laval in Russia manufactures plates and heat exchangers not only for domestic but also foreign consumers, since about half of the total volume of manufactured components is exported for complete set of heat exchange equipment in Western European countries. This is the best confirmation of the high world production standards. It should be noted that for production heat exchanger plates the highest quality steel is used. Plates for all models heat exchangers Alfa Laval are made according to the one-way stamping technology, which guarantees their complete identity and, as a consequence, an increase in the mechanical strength of the plate. In addition, the company Alfa Laval provides an exhaustive list of services for service, repair of heat exchange equipment and training of personnel.

Base of the plant's production program Alfa lavalFlow make up plate (gasketed) heat exchangers series M and TS, as well as seals, from special grades of rubber, the composition of which is being developed by the research team of the Swedish laboratory Alfa laval... Having vast technological experience and applying modern technologies and materials, alfa laval occupies a leading position in the world market in the field of heat transfer.

Heat exchangers alfa laval

Heat exchange equipment alfa laval used for heating liquid heat transfer agent in heating systems, in ventilation and hot water supply circuits, as well as for cooling oil, water, condensate and other liquids in various energy systems and in factory technological processes, due to the transfer of heat from the heating medium to the heated one. In this case, the heat carrier can be a different medium - both liquid and gas or vapor.

In the Elite in the direction of "kofmort" (creating comfortable conditions in the room) you can buy heat exchangers of two types: brazed heat exchangers (CB) and plate water heat exchangers (M, T)... In the industrial series (equipment used in technological processes), the main supplies fall on: heat exchangers AlfaRex, CompaBloc and TS(for steam).

The basis of the design gasketed plate heat exchanger make up corrugated plates, equipped with rubber seals, located between 2 plates, which are attached to the supporting beam and tightened with bolts.

Benefits of AlfaLaval gasketed and brazed plate heat exchangers:

• Unlike shell and tube plate water heat exchangers have a large heat exchange area, which provides higher performance, and smaller dimensions, and this allows the customer to save space for installation and money for transportation;
• Alfa Laval heat exchangers have a high heat transfer coefficient, due to the fact that more than 95% of the surface of each plate is used;
• The design of the plates includes a distribution platform that allows the coolant to be evenly distributed over the entire width of the plate and to prevent the appearance of so-called stagnation zones, which can potentially be foci of corrosion, which generally increases heat exchanger service life;
• ease of maintenance - when applied heat exchangers Alfa Love one person is enough to carry out periodic maintenance work, such as heat exchanger flushing and replacement of seals;
• possibility to increase power (adding plates gasketed heat exchangers);
• availability - price solutions of various configurations are varied, which will allow you buy heat exchanger, based on the specified characteristics of the engineering systems of your facility, system.

The price of a heat exchanger depends on the following criteria: the material of the steel used (316 or 304), the material of the seals, the correctly selected T curve, possible pressure losses of the head of the heating medium.

In Russia, the company has been known since 1992, when it launched its production of heat exchangers in one of the cities of the Moscow region on the basis of a former machine-building plant.

The main focus of the company is the improvement of energy efficient technologies. The range of this enterprise includes many different units, based on the Alfa Laval plate heat exchanger.

Externally plate heat exchangers Alfa Laval are no different from each other. Features only in the design of the plates and the sealing material. The manufacturer has developed unique technologies for the production and design of heat exchangers. Let's say the following can be distinguished:

1. One-step extrusion of plates. As a result, it became possible to obtain a homogeneous plate material and increase the level of heat transfer.
2. Special shape of the distribution surface. It makes it possible to rationally use the entire area of ​​the plates of the heat exchange equipment and make it less polluted.

Alfa Laval plate heat exchangers

Alfa Laval plate heat exchangers in Russia are quite common and are used by European and Russian manufacturers of refrigeration units as evaporators, condensers, superheated vapor coolers, heat exchange equipment for economizers and liquid / liquid structures among two refrigerants, etc.

The main advantages of plate-type heat exchangers are as follows:

1. High level of heat transfer. It is achieved due to the high turbulence during the circulation of the water flow inside the heat exchanger plates.
2. Low mass of refrigerant, which is in the heat exchange equipment at the time of operation. This provides a low mass refrigerant charge for a chiller that uses an evaporator or condenser as a plate heat exchanger.
3. Compactness when compared with other types of heat exchange equipment. Small dimensions allow the refrigeration unit as a whole to have significantly less weight.

The company has established the production of two main types of plate-type heat exchangers:

1. Lamellar collapsible (this includes lamellar collapsible-welded).
2. Alfa Laval copper-brazed plate heat exchangers.

Alfa Laval brazed copper heat exchangers are, at the same time, subdivided into the "CB" and "AC" series.

Alfa Laval is a Swedish manufacturer and remains a leader in manufacturing and development industrial equipment heat exchange of varying complexity.

Alfa Laval Swedish heat exchangers definitely deserve your attention and consideration!

If the bath has a high-quality stove, then a boiler is not required to heat the liquid that will enter the washing room. An Alfa Laval heat exchanger can be used for this. As his main function the heating of the incoming liquid acts and its return to the hinged tank. That is why, while the "heart" of the bath is burning, the water in the adjacent room will remain hot. After the bath stops heating, the water is drained. This is precisely the rationality of this idea.

Heat exchanger specifications

If you are interested in the manufacturer Alfa-Laval, you can select a heat exchanger from this supplier. How exactly will be described below. Sauna stoves equipped with a heat exchanger are structures in which there is a space where cold water enters. After its temperature rises, it begins to move through the pipes, moves to the hinged tank or radiators. In this case, the role of the heat exchanger for the sauna stove is not only to heat the liquid for the shower, but also to the portable tanks located in the rest room or dressing room.

Varieties

If you are interested in the Alfa Laval heat exchanger, then you should take into account that there are two variants of this design. Thus, the heat exchanger can be internal or external. In the first case, the device is a coil that runs along the bottom or is built into the side of the oven chamber. The coil is also called a jacket that completely covers the firebox. If we are talking about an external heat exchanger, it is a chimney module, or rather a pipe, which is surrounded by a sealed container.

Key Features

The Alfa Laval heat exchanger, whatever its appearance, is filled with a liquid, which can be water or antifreeze. The reporting tank is responsible for supplying liquid to the heat exchanger. The capacity is a hinged tank or a water heating battery. For connection, as a rule, two unions are used, one of them is located at the bottom, while the other is at the top. The principle of operation of the heat exchanger is extremely simple, everything happens due to the circulation of heated water or by connecting a pump, which must be powered by electricity.

Alfa Laval brazed heat exchangers are available for sale in wide range... Experts recommend choosing open systems heating the coolant in the bath, while the process will not be accompanied by pressure. It is also important that the most effective system heating the liquid in the bath is one whose total length of pipes does not exceed 3 meters. As practice shows, this will be enough to place the tank directly behind the wall of the steam room. It is important to pay attention to the thickness of the pipe, it is better if it turns out to be less than an inch, otherwise significant resistance will be rendered to the movement of water, while a bath stove with a heat exchanger, devoid of a pump, will not have the ability to distill water. If you have considered the Alfa-Laval heat exchanger and decided to make such a unit yourself, then you should be guided by the advice of experienced craftsmen. They recommend making this design using old radiators, which is true if suitable materials are not at hand. You can use car radiators or borrowed from the heating system. They will need to be combined, which will increase the heat exchange area. In the process of carrying out work, the use of adapters will be required.

Calculation of the area of ​​the heat exchanger

Experts emphasize that the calculations of the dimensions of the heat exchanger are usually the same. For example, heating a traditional room will require about 5 kW; this is the amount of energy that a stove with a heat exchanger should produce. As for one square meter of the heat exchanger area, this will be approximately 9 kW at the time of combustion. Undoubtedly, a lot will depend on the location of the boiler with the stove, as well as the intensity of fuel combustion. However, the power of the boiler after the completion of the firing process will drop 10 times. That is why it is necessary to calculate the surface area of ​​the heat exchanger with a certain margin, this is the only way you will be able to create a system that will be able to maintain a comfortable temperature in all rooms of the bath complex with a two-time or one-time firebox. Considering the Alfa-Laval plate heat exchanger, you should take into account that the shape of the boiler and the furnace can be very different. However, the most popular are those made of stainless steel pipes, however, those made of two channels are becoming more common.

Characteristics of the heat exchanger model Alfa Laval M3

If you paid attention to the Alfa-Laval plate heat exchanger, then before purchasing it is worth considering in more detail specifications... If we are talking about the aforementioned model, then it will be 3, 9 cubic meters... The plates of this variant of the heat exchanger have a surface area of ​​0.08 square meters. As for the maximum heat exchange area, it is equivalent to 3.9 square meters. The described model is small in size and very convenient to use, also a fairly compact design, it includes a frame that can withstand a maximum pressure of 16 bar. Among other things, the device is equipped with a plate. This model acts as a standard version of the gasketed plate heat exchanger, which consists of several plates. Frames are located on both sides. During the production process, the plates are given a corrugated surface, which makes it possible to provide high-quality heat supply through the transfer of liquid, which is in counterflow to each other. So that water does not flow into one another and does not flow out of the structure, the latter has a number of seals and gaskets, which are designed to protect the internal contents from the external environment.

Positive features of the Alfa Laval M3

Alfa Laval heat exchangers, the characteristics of which it will be useful for you to read before visiting the store, are a quality product that allows heating equipment to work efficiently. The unit of this series is also called a water heater because of the functions it performs. If we consider in more detail the technical characteristics of a heat exchanger of this kind, then some dimensions can be distinguished. Namely, the height of the unit, which is 480 millimeters, width (180 millimeters) and the maximum temperature equal to 180 degrees. The fluid consumption is 4 kilograms per second.

The Alfa-Laval heat exchanger, the technical characteristics of which will be of interest to every consumer, is presented in a one-pass design, the design does not have a support foot, which is also called legs. This model is necessarily supplemented with the necessary - passport and operating instructions. The documents will be required so that users have an understanding of the features of the equipment and are able to cope with problems encountered during operation. After all, the buyer will certainly have to service, carry out preventive work, clean the system, which will help effective work devices. After the Alfa Laval heat exchangers have been calculated, you can go to the store. This is the only way you can create a system that will have a high efficiency.

Conclusion

It is advisable to purchase the model of the heat exchanger that is recommended by the manufacturer. This will ensure that the design is suitable for a specific installation, and during operation you will not encounter failures.
