There are a few steps you can take to clean your heat exchanger:

  • Shut down the system and release all pressure.

  • Remove the plates from the heat exchanger.
  • Clean the plates with mild detergent and warm water.

If, after cleaning, you’re still experiencing blocked plate heat exchanger symptoms, it’s time to replace your gaskets.

Replace faulty Gaskets

Gasket failure is one of the most common causes of blocked heat exchangers.

If your gaskets are damaged, it’s important to replace them as soon as possible.

Failing to do so can result in expensive repairs down the line. It can also lead to more serious problems, such as leaks.

To replace your gaskets, you’ll need to purchase a new set from a heat exchanger supplier (like ourselves).

Once you have the new gaskets, remove the old ones and clean the mating surfaces.

Then, install the new gaskets according to the manufacturer’s instructions.

  • Gaskets can be replaced relatively easily, and it is a job that most professional PHE specialists can carry out.
  • Replacing the gaskets will help to ensure that your PHE is running efficiently.
