plate heat exchanger cleaning

Filson plate heat exchanger has a simple and lightweight structure. The composition or the parts of plate type heat exchanger is extremely easy to understand. Usually, it consists of a series of heat transfer plate, sealing gaskets and pressure plates at both ends.

The plate plays an important role in a Filson plate heat exchanger. It decides the heat transfer efficiency of the whole device. Herringbone/herringbone-shaped corrugated plate and horizontal corrugated plate is the frequently-used plate type in a plate heat exchanger.

plate heat exchanger heat transfer process

Generally, the plates of plate heat exchanger are designed into corrugated shape by Filson. It benefits a lot. This kind of design increases the flow rate of the fluids which indicates a high turbulence level to enhance the heat transfer efficiency. And the plates won’t be fouled easily because of the corrugation.

The gasket mainly acts as a seal between Filson heat exchanger plates. When select material of sealing gasket, you need take medias type into consideration. Commonly, the gasket is made of chemigum, EPDM(ethylene-propylene-diene monomer) and fluororubber.

plate heat exchanger installation

The pressure plates at the both ends of Filson plate heat exchanger are mainly used to clamp and fix all the heat transfer plate pieces to ensure that the fluid medium does not leak through the gap.

The main causes of plate heat exchanger leakage:

  • Corrosion and penetration of heat exchanger plates
  • Cracks on heat exchanger plates
  • Uneven tightening of clamping bolts
  • Extreme deformation of heat exchanger plates
  • Broken or aged sealing gasket
  • Uneven thickness of sealing gasket
  • Deflection of sealing gasket

Seven points above show the main causes of plate heat exchanger leakage, these remind you to maintain and recondition your plate heat exchanger more often to ensure its normal operation. However, Filson guarantees you a better outgoing quality to reduce maintenance and save costs.

Filson Plate Heat Exchanger Working Principle:

plate heat exchanger working principle

The heat exchange is carried out through the plates of a plate heat exchanger. Compare to conventional heat exchangers, the heat transfer coefficient is much higher under the same flow resistance and pump power consumption.

As one of the popular heat exchangers in the market today, plate heat exchanger creates a trend to replace shell and tube heat exchanger—the most frequently-used heat exchanger in some application ranges.

The plates are pressed into corrugated shape to increase the heat transfer area and rigidity. And it can make the fluid at low flow rate into the formation of turbulent flow in order to achieve the ideal effect and enhance heat transfer efficiency.

As shown in the figure, the four holes at the corner of the plate form the fluid distribution duct and drainage duct. Two kinds of heat exchange media flow into their respective channels forming counterflow or parallel flow through each plate for heat exchange.

What are the Components of a Plate Heat Exchanger?

The most important and the most expensive part of a plate heat exchanger, of course, is its thermal plates. The plates can be made of metals, metal alloys or even graphite materials. The selection of the material is always depended on the industry you are going to apply to.


Besides plates, a plate heat exchanger has the following components:

  • Sealing gaskets on the plates
  • Frame plate(fixed plate)
  • Pressure plate(movable plate)
  • Upper and lower bars
  • Screws for compressing the pack of plates
  • End support

How does a Plate Heat Exchanger work?

Plate heat exchanger consists of many thin and corrugated plates at certain intervals. The plates are sealed around by gaskets and overlapped with the frame and compression screws.

The four corner holes of the plates and gaskets form the distribution and collection tubes of fluid. And at the same time, a reasonable separation of hot and cold fluids is realized, so that the fluids pass through the flow channel on both sides of each plate. Then the heat exchange carries out.

working principle of plate heat exchanger

Where are Plate Heat Exchangers used?

Plate heat exchanger has been widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, paper making, light textile, shipping, heating and other departments.

In addition, plate heat exchanger can be used for heating, cooling, evaporation, condensation, sterilization, waste heat recovery and other occasions.

What are the Advantages of Plate Heat Exchanger?

Plate heat exchanger is becoming popular and popular in the market today, it surely has lots of advantages of using a plate heat exchanger.

(1) High heat transfer coefficient

The flow channel of plate heat exchanger is small and narrow, the plate is corrugated and the cross-sectional changes are complex. These all lead to the constantly changes of the flow direction and flow velocity which increase the fluid disturbance. Thus it can reach turbulence at a very small flow rate to reach a high heat transfer coefficient.

(2) High adaptability

The design of plate heat exchanger allows it to achieve the required heat transfer area by increasing or decreasing the plates. A plate heat exchanger can be divided into several units and can be adapted to satisfy simultaneous heating or cooling between several fluids.

(3) Compact structure, small volume and less consumable materials

The heat transfer area of each cubic meter plate heat exchanger can reach 250㎡. And only about 15 kg of metal is required for each square meter of heat transfer surface.

(4) High heat exchange efficiency

High heat transfer coefficient and low metal consumption of the plate heat exchanger make the heat transfer efficiency up to 85% or more than 90%.

(5) Easy to disassemble, wash and repair

Plate heat exchanger has really simple structure — plates and frames, so after a period of use, you can easily remove the plates and wash them, or replace with a new one.

(6) Small possibility of scaling

Due to the large disturbance of flow, fouling is not easy to deposit. At the meantime, the plate is made of quality material, so there is little corrosion to make the plate scale.

(7) Competitive price

Filson plate heat exchanger is mainly formed with metal plates, such as stainless steel, carbon steel, titanium, aluminum, nickel. So the price of raw materials is lower comparing to the same metal tubes.

quality plate heat exchanger for all sorts of applications

What are the Differences Between Plate Type Heat Exchanger and Shell and Tube Heat Exchanger?

Though both plate type heat exchanger and shell and tube heat exchanger are frequently used in industrial applications, they still have many differences in distinct aspects.

1. Structure comparison

Shell and tube heat exchanger is the most widely used heat exchanger in chemical production at present. It mainly consists of shell, tube bundle, tube sheet, baffle, end cover and other elements.

Plate heat exchanger has a relatively simple structure. It mainly consists of plate, gaskets, upper and lower bars, frame plate, pressure plate and bolts.

2. Heat transfer performance comparison

Plate heat exchanger has higher heat transfer coefficiency for the turbulence. Generally, the coefficiency is considered to be 3 to 5 times of shell and tube type heat exchanger.

3. Volume comparison

Compare to shell and tube heat exchanger, plate type heat exchanger has a compact structure and smaller floor space. The heat exchange area per unit volume is 2 to 5 times that of shell and tube type.

Typically, there will be a maintenance site for the extracted tube bundle at the design part of a shell and tube heat exchanger, that’s one of the reason why it has larger volume than a plate type heat exchanger.

4. Process and design comparison

For a plate type heat exchanger, it is easy to change the heat exchange area or process combination.

You can add or reduce the plates casually to achieve the purpose of increasing or decreasing the heat exchange area. And if you want to change the plate arrangement or replace several plates to meet required effect, it also easy to realize.

However, the heat transfer area of a shell and tube heat exchanger is almost impossible to change, especially for a fixed tube sheet shell and tube heat exchanger.

5. Price comparison

When it comes to the factor that customers care about most, that must be the price. The plate heat exchanger costs about 40% to 60% lower than a shell and tube heat exchanger under the same heat exchange area and with the same manufacturing material.

Without doubt, different types of heat exchanger have different advantages and disadvantages, just choose the most suitable one to fit your specific application. By the way, shell and tube heat exchanger is also available to be provided by Filson.

shell and tube VS plate type heat exchanger

What is the Limitation of Plate Heat Exchanger?
  • Temperature and pressure limitations

This important limitation is related to the plate gaskets. Plate heat exchanger is sealed with gaskets. Its working pressure should generally not exceed 2.5 MPa and the medium temperature should be below 250℃, otherwise there is a risk of leakage.

However, if the gaskets are made of special materials, they may withstand temperature up to 450℃. Or maybe welding and brazing the plates to each other is also a good choice for operation under more tough conditions. But it surely is more expensive.

  • High pressure drop

The space or the channel between the corrugated plates is small and narrow. When the fluids flow between the plates, the pressure drop will be high due to the friction, then it may increase the pumping cost.

  • Leakage possibility

The metal plates sometimes will be worn because of the friction and will form the small holes that are difficult to locate. That increases the leakage possibility. So the regular maintenance is necessary. (The possible causes of leakage are listed in the body part.)

  • High material costs

If you choose titanium as the manufacturing material of your plate heat exchanger, the initial cost is high. And since the titanium is a noble metal with good property, other components involving in the plate heat exchanger may be corroded.

  • Congestion problem

As the channel between the plates is very narrow, generally only 2 to 5mm, when the heat exchange medium contains larger particles or fiber material, it is easy to lead to the congestion problem.

Which Heat Exchanger Flow Type is the Most Efficient?

There are three flow types in the heat exchanger, they are:

  • Parallel flow
  • Cross flow
  • Counter flow

Among which counter flow is the most efficient comparing to the other two types. For parallel flow, the fluids pass through the heat exchanger in the same direction. However, as for counter flow, the fluids flow against each other in opposite directions.

Counter flow creates a more uniform temperature difference between the fluids through the entire heat exchanger. Further, since the temperature difference is more even, the heat exchange rate is also more consistent.

How do I Choose the Right Plate Heat Exchanger?

When choose the plate heat exchanger, you should take many factors into consideration, like the applications you are using a heat exchanger in, the fluids characteristics, working pressure and temperature…

Filson has a professional team of engineers, workers and sales with rich experience in heat exchanger. So you don’t need to worry about how to select the right plate heat exchanger for your industry, just send your specifications or requirements, Filson will solve your problems.

How to Clean My Plate Heat Exchanger?

Plate heat exchanger, a corrugated high-efficiency heat exchanger, is now commonly used in various industries. But long-term use will cause fouling, so you are recommended to clean your plate heat exchanger after a period of use.

Some substances after heating will be decomposed into calcium carbonate—a kind of deposit which will precipitate in the heat exchanger. Then a thick layer of scale will be formed over time. At the same time, loose and non-fixed shape magnesium hydroxide is generated which makes the formation of scale more easily.

When clean the plate heat exchanger, you are supposed to disassemble the frame and plates. Its cleaning method is to use acidic cleaning agent for cleaning.

At present, the using cleaning agents are mostly organic or inorganic acids. Acid cleaning can effectively help remove scale because acid can dissolve and destroy the structure of the scale, so that you can achieve a good cleaning effect.

12. How Long do Plate Heat Exchangers Last?

It depends.

The life of a plate heat exchanger is determined by the application. In general, a plate heat exchanger can last for more than 8 years.

But in the most common chemical processing industry, the plate heat exchanger always works under the tough conditions with high temperature, pressure and corrosion, thus those equipments has a relatively shorter lifespan of 2 or 3 years.

Even in some heavy duty factories, they change plate heat exchanger once a year.

plate heat exchanger maintenance

13. What is the Minimum Temperature Difference You Can Have Between the Two Sides of a Plate Heat Exchanger?

Generally speaking, the minimum temperature difference between the two sides of a plate heat exchanger is 5 to 2℃.

Sometimes for a plate heat exchanger, 1℃ temperature difference between the two sides can be realized. But it has to meet a certain condition, that is, the heat transfer area should be large enough and the water flow of the cold end should also be as large as possible.

understand temperature difference between two plates

Can I Use Any Type of Media in a Plate Heat Exchanger?

Of course not any type of media can be used in a plate heat exchanger.

As plate heat exchanger is an ideal device for liquid to liquid and liquid to gas heat exchange, the type of media can be water, oil, milk, cosmetics, pharmaceuticals and other medias. But you’d better not use viscous fluids in a plate heat exchanger.

If you are not sure that whether the media is available in your plate heat exchanger, just feel free to inquire our professional specialists. They will solve your problems patiently.
