Tank Integration Applications

Pillow plates can also be installed inside tanks as internal heat exchange surfaces.

In this configuration, they:

• Provide uniform temperature distribution
• Improve mixing in agitated tanks
• Act as flow-guiding surfaces for better process control

Advantages of Pillow Plate Heat Exchangers

Pillow plate heat exchangers offer several advantages compared to traditional shell and tube or plate heat exchangers.

1. High Heat Transfer Efficiency

The dimpled structure creates turbulence, significantly improving heat transfer coefficients.

2. Customizable Design

Pillow plates can be customized in:

• Shape
• Size
• Thickness
• Material

This makes them suitable for a wide range of industrial applications.

3. Excellent for Fouling and Dirty Media

Pillow plate heat exchangers perform well in:

• High-fouling fluids
• Scaling media
• Slurry or particulate-containing fluids

They are widely used where traditional plate heat exchangers fail due to clogging.

4. Suitable for High Temperature and Pressure

Since pillow plates are fully welded and do not require gaskets:

• They can operate under high pressure
• They tolerate high temperatures
• They require less maintenance

5. Low Maintenance Design

External surfaces are easy to clean using:

• Water washing
• Chemical cleaning (CIP)
• Steam cleaning

However, internal channels are not mechanically accessible and require chemical cleaning or backflushing.

6. Wide Range of Applications

Pillow plates can be used for:

• Liquid-to-liquid heat transfer
• Gas-to-liquid heat recovery
• Gas-to-gas heat exchange
• Solid-to-fluid heating
