Alfa Laval's business activities mainly focus on one thing: providing you, as a user, with various technologies and solutions in order to help you to provide further optimization measures in the key process equipment you run in a wide range of categories. In the industrial field, virtually all kinds of process technologies involve some form of heating or cooling treatment. Because of this, Alfa Laval focuses its business on various heat exchange technologies and solutions.

In any form of heating and cooling treatment, one way to maximize the benefits is to maximize the use of all the heat energy generated in the system, instead of producing or purchasing expensive heat energy separately.

Heat conduction involves placing two substances at different temperature levels close to each other. In this way, one substance can heat or cool another substance. This means that the purchased energy existing in the system is transmitted to another part of the process in a simple way for use, thus making the energy play its maximum benefit. This not only saves money and energy consumption, but also reduces the possible impact of the production process on the overall environment.

In the field of heat exchange technology, only the largest and best companies can have resources and core technology advantages to provide a wide range of heat exchanger solutions. Alfa Laval is one of them, which can provide optimal heat conduction technology to meet your various application needs.

Heat conduction technology - one choice In a broad sense, shell and tube heat exchanger is a large, traditional solution; Spiral plate heat exchanger is a relatively simple solution with small volume; The plate heat exchanger is a compact and modern solution - it has high thermal efficiency and the best technical advantages.

Alfa Laval hopes to provide you with optimal solutions. Therefore, we have been making great efforts to develop and utilize the plate heat exchanger technology.

Realize optimal heat conduction According to the design, the plate heat exchanger can perform the optimal heat conduction work, because the corrugated heat exchange plate has the largest surface area so far. Through the surface of the heat exchange plate, heat can be transferred from one gas or liquid to another medium. Although such a large heat conduction surface can be provided, the structure of plate heat exchanger equipment itself is usually quite compact. For example, Alfa Laval's "Compabloc" solution is currently the most compact device on the market. It only needs to occupy about 20% of the area of the traditional equipment installation site. The design configuration of the channel can also ensure that turbulence is generated to the maximum extent when every fluid passes through. In this way, the maximum heat exchange efficiency from one medium to another is formed.

working principle

The basic plate heat exchanger consists of a series of corrugated thin heat exchange plates. These heat exchange plates are connected together by sealing gasket or welding (or by any synthetic method). The connection mode not only depends on the nature of the liquid flowing in them, but also depends on whether to disassemble the plates and other factors in the future. These heat exchange plates are then placed in a solid frame and pressed firmly to form a horizontal fluid channel layout. One fluid flows through odd channels, while the other flows through even channels.

Internally determined differences

From the appearance, all plate heat exchangers are similar in shape. The real difference lies in its internal quality, which lies in the subtlety of the heat exchanger plate design and the sealing technology used.

Alfa Laval is the world's largest manufacturer of plate heat exchangers and can provide a variety of solutions. The design and manufacturing process of plate heat exchanger adopted by us have formed a system and reached a unique level. Specifically

One time press forming technology of heat exchange plate - ensures better balance of plate, less physical stress, thinner plate thickness, and more effective heat conduction performance:

The patented design of the flow distribution area ensures that the function of the heat conduction area can be maximized, the turbulence can be maximized in the fluid, the optimal fluid distribution can handle the requirements of higher design pressure and the possibility of minimum scale generation: our company is able to provide you with a full range of fully optimized plate heat exchanger designs The size and application can meet the specification requirements of any kind of operation under actual conditions:

The plate heat exchanger provided by Alfa Laval can be supplied to you in the following combinations:

The heat exchange plates are connected by sealing gasket or welding (or by any synthetic method). The sealing gasket materials and adhesives used have a variety of specifications and have been carefully studied and selected:

Single phase heat conduction mode with two kinds of liquids, or two-phase application with one way of gas and one way of liquid, as well as condenser, evaporator and reboiler;

For applications with great differences in temperature and pressure, as well as handling fluids with different purity, viscosity and solid/fiber content:

As a "two in one" device, it can fully manage the temperature and fluid flow through the device as required:

For a series of different practical applications, from the most corrosive and very severe operating environment conditions, such as nuclear energy industry and offshore oil and gas exploration equipment, to the fine processing of drinks and food.

Welding of heat exchange plates completely welded together, the temperature and pressure limits that can be tolerated can be extended to 350 ° C (650F) and 40 bar

Bonded sealing gasket If your operating environment will promote the expansion of the sealing gasket, bonded sealing gasket can provide you with higher reliability. This is especially applicable to operating points that need to be frequently opened. No special technical support is required to replace the bonded sealing gasket. The epoxy resin that can be cured by oven heating provided by our company can be used to firmly stick the sealing gasket without disintegration and dissolution.

Non bonded sealing gasket Non bonded sealing gasket allows users to quickly and easily replace the sealing gasket on the job site
