Plate condenser L300

Plate condenser is a new type of highly efficient heat exchanger composed of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between various plates, and heat exchange occurs through half plates. Compared with the conventional shell and tube heat exchanger, under the same flow resistance and pump power consumption, its heat transfer coefficient is much higher, and there is a trend to replace the shell and tube heat exchanger within the applicable range.

What is a plate condenser?

Plate condensers are specialized equipment used for condensing steam in evaporation or distillation systems. They are based on semi-welding technology and consist of special plate groups and gaskets. During operation, the cooling medium flows and heats up in the channel with a gasket, while the steam condenses in the welding channel on the other side. This equipment is equipped with a large-sized steam inlet and a small-sized condensate outlet.
Working principle of the plate condenser

The plate condenser significantly enhances the influence of flow rate on condensation heat transfer through narrow flow channels and top-down steam flow. When steam flows in the same direction as the liquid film, the force will thin the liquid film and enhance heat transfer. When reversed, it thickens the liquid film and deteriorates heat transfer. However, once the force exceeds gravity, the liquid film is carried away from the wall surface, and the heat transfer coefficient will increase sharply. This design not only enhances heat transfer but also achieves low pressure drop and smooth discharge of condensate.
Characteristics of Plate Condenser

1)The addition of vertical ribs on the plates aims to achieve a dual effect: one is to form unequal flow channels, and the other is to significantly enhance heat exchange efficiency by creating turbulence.
2) After the diameter of the opening on the steam side was increased to 700mm, reinforcing ribs were set around it to compensate for the weakened rigidity of the plate. Empirical calculations and hydrostatic tests confirm that this design can meet the rigidity requirements.
3) The chocolate flow diversion zone is formed by using completely symmetrical mesh flow guide blocks. Its advantage lies in that it can force the fluid to be distributed throughout the entire heat transfer area. Meanwhile, the design of symmetrical node superposition also provides effective rigid support for the plates, ensuring the stability of the wide flow channels.
Advantages of Plate condensers

1) Performance advantages: Compared with the tubular type, the plate condenser has a better structure under the same working conditions (more compact, lighter, and lower cost), and due to the smaller flow channel equivalent diameter, its heat exchange capacity (Q), heat exchange capacity per unit area, and heat transfer coefficient (K) are significantly increased by 16.79%, 76.63%, and 89.11% respectively, showing great potential for substitution.
2) Design features: In addition to the common advantages of plate heat exchangers such as high efficiency, light weight, compness, easy cleaning, and high elasticity, it also features unique designs like low resistance, low pressure drop, inclined corrugations, wide channels, and large connecting pipes. These designs not only enhance the heat transfer coefficient but also effectively control the water pressure drop for cooling.
3) Application value: Widely applied in various evaporation steam condensation processes, it can recover cooling water and significantly reduce costs. Its applicable scenarios include the condensation of low-pressure steam, secondary steam, fractionation systems, small power plants, and light fuels such as jet fuel. It has a remarkable effect in replacing traditional mixed condensers, with outstanding economic and environmental benefits.

FAQ

What is a Plate Condenser and how does it work?
+

A Plate Condenser is a compact and efficient type of heat exchanger used to condense vapor or steam into liquid by transferring its latent heat to a cooling medium (typically water or air). It consists of a series of corrugated plates assembled together. The vapor flows in alternating channels, comes into contact with the cooler plates, condenses, and releases its heat to the cooling fluid flowing in the adjacent channels.
What are the main advantages of using a Plate Condenser over a traditional Shell and Tube Condenser?
+

Our plate condensers offer several key benefits:
Higher Efficiency: The corrugated plates create high turbulence, leading to superior heat transfer coefficients and very close temperature approaches.
Compact Size & Light Weight: They can provide the same duty as a shell and tube unit in a fraction of the space and weight, reducing installation costs and footprint.
Lower Cost: Often, both the initial investment and the total cost of ownership are lower due to reduced material and installation requirements.
Flexibility & Scalability: Capacity can be easily adjusted by adding or removing plates in a frame (for gasketed models).
Reduced Fouling: High turbulence helps minimize scaling and fouling.
What types of Plate Condensers do you offer?
+

We provide the right condenser for every application:
Gasketed Plate Condensers: Ideal for non-hazardous, non-corrosive applications like HVAC and standard process cooling. They offer easy maintenance and cleanability.
Fully Welded Plate Condensers: Designed for high-pressure, high-temperature duties, corrosive media, or applications where gasket failure would be critical (e.g., with refrigerants or toxic vapors). They are gasket-free and highly durable.
Brazed Plate Condensers: A compact, cost-effective solution for smaller systems, commonly used in refrigeration and chiller units.
How do I clean a Plate Condenser? Is it difficult?
+

The cleaning process depends on the type:
Gasketed Models: These are the easiest to clean. The unit can be opened, and the plates can be mechanically or chemically cleaned individually.
Fully Welded Models: While not openable, many are designed to be cleanable in place (CIP) using chemical solutions. Some fully welded designs also allow for mechanical cleaning from one side.
Brazed Models: These are generally not cleanable and are intended for clean, closed-loop systems.
We will recommend the best type based on your fluid's fouling potential.
What materials are your plates and gaskets made from?
+

Plates: We offer a wide range, including Stainless Steel 304/316, Titanium (for chlorides), Hastelloy (for highly corrosive chemicals), and Nickel alloys.
Gaskets: For gasketed models, we use various elastomers like NBR (standard), EPDM (for high temperatures), and FKM/Viton (for aggressive chemicals and oils), ensuring compatibility with your specific media.
