One of the leaders in the world market for the production and development of new types of heat exchange equipment for various purposes is the Swedish company Alfa Laval Lund AB. Founded in 1883, it successfully operates today.
Alfa Laval heat exchangers of 2 types have won the greatest popularity in the markets: Alfa Laval heat exchanger is collapsible and brazed. Each of these types has certain advantages that make their use in a particular case more rational.
The main activity of the company is devices that provide separation (separation), heating, cooling, transportation of various liquid substances, including chemical reagents, petroleum products, medicines and food liquids, bulk mixtures - these are heat exchangers. This is a large international company that has a number of patents for unique PHE designs used in heat exchange equipment of plates, frames, gaskets, has know-how in the field of technological solutions and uses only high quality materials in its activities, which ensures a decent level of end products, its long service life and reliability.
Today, the need for such devices is quite wide and they are used in many countries of the world in the field of centralized water supply, which includes the supply, including hot water, as well as in air conditioning and the creation of ventilation systems for buildings and structures. Steam or water acts as a heating medium.
Alfa Laval heat exchangers - key benefits
- In PHE, plates with a thickness of 0.5 mm are used and they are made by one-way extrusion. Thanks to this production method and the special profile of the flow channels, stiffness and strength of the structure, a long service life, efficient heat transfer and reliability are achieved;
- The number of possible leaks is minimized due to the precise placement of the plates, which is ensured by the special frame design. This allows for multiple disassembly and assembly, as well as changing its area by removing or adding additional plates;
- The possibility of repeated cycles of disassembling and assembling the PHE is achieved by using seamless gaskets, the fixation of which is not based on the use of adhesives. In addition, the profile of the gasket is a patented technical solution, since it is he who is responsible for the tightness of the working space and, due to this, the long life of the gasket.
A heat exchanger is a unit in which heat is transferred from a working environment with a high temperature to the final heat consumer - a cold environment with the assistance of corrugated plates sandwiched between two powerful panels that hold them together. In some cases, this may not be a collapsible heat exchanger with an area of 0.2 sq.m., in others, collapsible units, the performance of which, if desired, can be increased.

Spiral devices - the main advantages
Spirals are most often used in the treatment of liquids containing solid particles, sediments of various compositions, as well as sludge, suspensions and viscous liquids. Small devices can also be used successfully in wastewater treatment.
A modern spiral type heat exchanger is that in their design they resemble a clock spring, which consists of two metal sheets twisted to form channels. In this case, the liquids that pass through these channels do not mix, but at the same time, high quality heat transfer and the most suitable parameters of flows that differ in viscosity, composition and intensity are ensured. Since the channels have a concentric design, they do not require a lot of space for installation, which saves a lot of usable area that can be used for production purposes.
Heat exchanger - principle of operation
Collapsible sink PTO
If the bath has a high-quality stove, then a boiler will not be required to heat the liquid that will flow into the washing room. An Alfa Laval heat exchanger can be used for this. Its main function is to heat the incoming liquid and return it to the mounted 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.
Specifications of the heat exchanger
If you are interested in the Alfa Laval manufacturer, you can select a heat exchanger from this supplier. How exactly will be described below. Bath 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, moving towards the hanging tank or radiators. At the same time, the role of the heat exchanger of the bath stove is not only to heat the liquid for the shower, but also to remote tanks located in the rest room or dressing room.
Varieties
If you are interested in the Alfa Laval heat exchanger, then you should consider that there are two versions of this design. Thus, the heat exchanger can be internal or external. In the first case, the device is a coil, which is launched along the bottom or built into the side of the furnace chamber. The coil is also called a shirt, which 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 type it may be, is filled with a liquid, which can be water or antifreeze. The reporting tank is responsible for supplying liquid to the heat exchanger. Capacity is a hinged tank or a water heating battery. For connection, as a rule, two fittings are used, one of them is located below, while the other is located on 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 that must be powered by electricity.
Alfa Laval brazed heat exchangers are commercially available in a wide range. Experts recommend choosing open systems for heating the coolant in the bath, while the process will not be accompanied by pressure. It is also important that the most efficient system for heating the liquid in the bath is the 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 there will be considerable resistance to the movement of water, while a sauna 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 were 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 course of the work, the use of adapters will be required.
Calculation of heat exchanger area
Experts emphasize that the calculations of the dimensions of the heat exchanger, as a rule, are the same. For example, it will take about 5 kW to heat a traditional room, this is the amount of energy that a furnace with a heat exchanger should produce. With regard to one square meter of heat exchanger area, this will be approximately 9 kW during the combustion. Undoubtedly, much will depend on the location of the boiler with the furnace, as well as the intensity of fuel combustion. However, the power of the boiler after the completion of the combustion process will drop by 10 times. That is why the surface area of the heat exchanger must be calculated with some margin, only in this 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 furnace can be very different. However, the most popular are those made of stainless pipes, however, those made of two channels are becoming more common.
Characteristics of the Alfa Laval M3 heat exchanger
If you have paid attention to the Alfa Laval plate heat exchanger, then before purchasing it is worth considering in more detail the technical characteristics. If we are talking about the above 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 quite 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 a 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 by transferring fluid that is in countercurrent to each other. In order to prevent water from flowing into one another and from flowing out of the structure, the latter has a number of seals and gaskets that are designed to protect the internal contents from the effects of the external environment.
POSITIVE FEATURES Alfa Laval M3
Alfa Laval heat exchangers, whose characteristics 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.

Namely, the height of the unit, which is 480 millimeters, the width (180 millimeters) and the maximum temperature, equal to 180 degrees. The fluid flow 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 single-pass design, the design does not have a support heel, which is also called legs. This model is necessarily supplemented with the necessary one - a passport and an instruction manual. Documents will be required so that users have an idea about the features of the equipment and are able to cope with problems encountered during operation. After all, the buyer will certainly have to maintain, carry out preventive work, clean the system, which will help the efficient operation of the device. After the calculation of Alfa Laval heat exchangers has been made, you can go to the store. Only in this way can you create a system that will have a high efficiency.

The main direction of the company is the improvement of energy-efficient technologies. The range of this company includes many different units, based on the Alfa Laval plate heat exchanger.
Externally, Alfa Laval plate heat exchangers do not differ from each other. Features only in the design of the plates and sealing material. The manufacturer has developed unique production technologies and designs of heat exchangers. Let's take the following:
- One-step pressing of plates. As a result, it became possible to obtain a homogeneous material of the plates and to increase the level of heat transfer.
- Special shape of the distribution surface. It makes it possible to rationally use the entire area of the plates of heat exchange equipment and make it less polluted.
Alfa Laval plate heat exchangers
Alfa Laval plate heat exchangers are quite common in Russia and are used by European and Russian manufacturers of refrigeration units as evaporators, condensers, superheated vapor coolers, economizers heat exchange equipment and liquid / liquid structures between two coolants, etc.
The main advantages of plate-type heat exchangers can be distinguished as follows:
- High level of heat transfer. It is achieved due to high turbulence during the circulation of the water flow inside the heat exchanger plates.
- Small mass of refrigerant, which is in the heat exchange equipment at the time of operation. This provides a low refrigerant charge for a chiller that uses an evaporator or condenser as a plate heat exchanger.
- Compactness when compared with other types of heat exchange equipment. Small dimensions allow the refrigeration unit as a whole to have a significantly less weight.
The company has launched the production of two main types of plate-type heat exchangers:
- Lamellar collapsible (this includes lamellar collapsible-welded).
- Alfa Laval brazed copper plate heat exchangers.
Alfa Laval copper-brazed heat exchangers, however, are divided into the "CB" and "AC" series.
| Brazed copper heat exchanger series | Peculiarities |
