Compabloc Heat Exchanger Reconditioning and Cleaning

The process of reconditioning and cleaning a Compabloc heat exchanger involves the steps below. This process ensures your Compabloc welded heat exchanger continues to perform as designed and that the energy losses are minimized over the lifetime of your heat exchanger.

Reconditioning a Compabloc involves the following steps:

  • Inspecting the unit for leaks, internal leaks (cross contamination),
  • Chemical or heat exchanger mechanical cleaning
  • Attaching Alfa Laval factory-certified new gaskets.
  • A final hydro testing to the design pressure and making sure the bolts are tightened according to the unit's manual.

Servicing a Compabloc Heat Exchanger 

Servicing a Compabloc heat exchanger at one of our Canadian facilities brings your equipment back to its original performance. Using Alfa Laval Reconditioning Services ensures that the equipment performs and is as reliable as the original manufacturer's specifications.

Alfa Laval's workshops are located in Alberta and in Ontario. We clean, recondition, overhaul, rebuild and repair your heat exchanger according to your specific needs, summarizing our activities in a report once the work is completed.

Our state-of-the-art Alfa Laval Service Centres, which use the latest technologies and environmentally sound process, provide the same high quality of service regardless of location.


Let Alfa Laval reduce your maintenance costs over the lifetime of your Compabloc heat exchangers. 

Ten top tips Alfa Laval CompablocTen Top Tips To keep your Compabloc in tip top condition

  1. Ensure that key operating conditions (pressure, temperatures and flow rates) match the original design specifications.

  2. Use pre-filters and strainers to protect the Compabloc from foreign objects and fouling.

  3. Open and close valves slowly to avoid water hammer from pressure surges during start-up and shutdown.

  4. Make sure that the unit is properly vented. For large units the vent connections should be kept opened/connected.

  5. To ensure stable operation and smooth temperature and pressure ramp up during start up or shut-down, check that the control system complies with the Compabloc manual.

  6. Use predictive maintenance including regular checks of the pressure drop to determine the Compabloc heat exchanger cleaning frequency required.

  7. Use chemical Cleaning-In-Place (CIP) or mechanical cleaning (steam or high pressure water jets) to remove deposits and fouling to avoid having to open the exchanger unnecessarily.

  8. Panel gaskets must be changed after each panel opening, so keep a spare set of panel gaskets on site.

  9. Operations of a Compabloc heat exchanger.jpgAfter a long shutdown, double-check the tightening torque of all panel bolts before re-starting operation.

  10. In case of an external leakage, through the gasket, tighten the panel bolts to nominal torque values or replace the panel gaskets. If the leakage cannot be fixed, contact Alfa Laval for advice. Field repair and cleaning may be possible.
