Service Center

The scope of the heat exchanger service, including the total price, is always agreed upon and confirmed in advance, ensuring full control over the service and its costs.

In our modern service center, we restore heat exchangers to full performance, tightness and reliability. We address fouled plates, deposits, leaks, hidden damage, upgrades and modernization.

Chemical bath cleaning gently removes both organic and mineral deposits, thoroughly cleaning even the internal structure of the heat-exchanger plates.

UV Plate Inspection reveals hidden cracks or damage that are not visible to the eye.

The usual service interval is 1–3 years, but it depends on:

  • the type of medium (hard water requires shorter intervals),
  • operating load,
  • temperatures,
  • the presence of oils and contaminants,
  • the heat exchanger manufacturer.

In industrial operations, food processing, or systems using hard water, annual servicing is recommended. For less demanding applications a 2–3 year interval is usually sufficient.

A clogged heat exchanger can be identified by several warning signs:

  • a higher temperature difference between inlet and outlet,
  • reduced flow or increased pressure drop,
  • longer heating times or slower system performance,
  • higher energy consumption,
  • vibrations, noise or irregular operation.

These issues occur due to deposits (scale, sludge, oil layers) that reduce heat transfer efficiency.

Mechanical cleaning is suitable for heavy deposits, hard scaling and fouling on plates or tubes, but it usually requires partial disassembly of the unit.
Chemical cleaning (CIP) is ideal for limescale, corrosion and organic buildup. It is performed without dismantling and is time-efficient.

In practice, both methods are often combined: CIP first, followed by gentle mechanical finishing.

Most heat exchangers can be effectively cleaned without disassembly using chemical CIP.
Disassembly is required only when:

  • the heat exchanger is heavily corroded,
  • nozzles or deep channels are clogged,
  • gaskets or damaged plates need to be replaced,
  • there is suspicion of leaks or mechanical wear.
Modern plate heat exchangers are designed to be serviced directly on-site.

The service price usually depends on:

  • the size of the heat exchanger,
  • the type of cleaning required (mechanical / CIP),
  • whether gaskets, plates or other components need to be replaced
  • the distance and time required for a technician to come on-site.

Yes. Regular servicing keeps the heat exchanger clean and efficient, which means it requires less energy to transfer the same amount of heat. As a result, the entire system can operate more economically and with lower operating costs.
