Heat conductive and exchanger coating series

To improve the protection of heat exchangers and its tubes, CP Phenolics offers a specially developed phenol coating series. These coatings are heat conductive and can withstand large temperature fluctuations between -120°C and 220°C. The heat exchanger protection coating is extremely resistant to strong alkaline to acid media. Its most important features are:

  • Erosion protection
  • Corrosion protection

    Baked Phenol coating protects the plate of the Plate Heatexchanger

    Coated plateheatexchanger

  • Anti-fouling
  • Flow improvement

Depending on the type of exchanger we can apply the coating using:

  • Flooding technique
  • Tube lining technique
  • Immersion technique
  • Spraying technique

The process of a heat exchanger protection coating

Heat-cured phenol epoxy coating:

A heat exchanger is a very important part in the chain of processes. It is therefore essential to ensure its reliability and optimum performance. To achieve this, a good conservation is required. Through years of experience in the field we have learned us that our CP Phenolics® coating (phenolic epoxy coating) has such outstanding characteristics to meet even the toughest of expectations.

CP Phenolics ® heat cured coating systems bring great value to customers thanks to their high chemical resistance to aggressive media even in high concentration and high temperatures (up to 220°C).
The CP Phenolics® coating prevents corrosion and fouling and incrustation in the tubes. Consequently, by applying the coating on a heat exchanger tubes, optimal protection is guaranteed and operational costs are reduced. The heat conductivity remains almost constant which results in better efficiency and allows for a simple cleaning process.

Benefits of a coated shell tube

Treatment of an heat exchanger’s shell tube with a CP Phenolics® coating will lead to:

  • Low resistance coefficient (maximum flow through the tubes)
  • Optimal heat transfer
  • High operational reliability
  • Extended lifetime of the heat exchanger
  • Protection against galvanic corrosion

Application description

The coating is a thermosetting coating of minimum DFL of 180 mµ. It is applied in multiple sessions where every session gets an oven treatment on a different time and temperature schedule. During the final polymerization session, the coating sessions cross link with each other on molecular level. As a result, the coating offers high-end corrosion protection against all sorts of aggressive substances that can lead to deterioration of the heat exchanger tube.

Cost reduction

The aforementioned properties will ensure that your investment and maintenance costs will be reduced. We therefore recommend not only to provide a protective coating on new heat exchangers but also on those who are already in use.

Example case Project BASF

Entry temperature of condensate: 98 – 103 °C, cooling water speed: 0.3 m/sec.

Conclusion

Due to the absence of our protective coating, the heat transfer reduced more than 60% in 36 months!
