4 - OPERATION
4.1 - Commissioning
- Make sure that the heat exchangers do not operate under conditions that are more challenging than the design conditions
(pressure, temperature, flow rate, fluid type).
- Make sure that the tightening dimension matches that shown on the data plate. Never allow this dimension to fall below the
minimum value indicated.
- Open the valves slowly to avoid water hammering and thermal shocks,starting with the hot circuit and then the cold circuit.
Sudden changes in temperature or pressure as well as a sudden intake of hot fluid in a cold unit (or vice versa) may damage the
gaskets and plates and cause leaks.
- Make sure that the heat exchanger is not subject to vibrations or frequent stops/restarts.
- Drain the air from the two circuits after circulating the fluids. Air left inside the circuits may cause product overheating, reduce
the exchanger’s efficiency and increase the risks of corrosion.
4.2 - Post-commissioning tests
After running the system for one hour:
- Check that there are no leaks; small leaks during commissioning are normal.
- Check the pressures and temperatures of all the fluids being circulated.
5. MAINTENANCE
- All maintenance operations must be carried out by qualified, trained personnel.
- The heat exchanger may not be altered in any way without CIAT’s consent.
- As the maintenance intervals depend on several parameters (fluids, temperature, etc.), the frequency of preventive maintenance
is left to the operator’s judgment. Nevertheless, a maintenance inspection is recommended at least once a year.
- Periodically check the condition of the corrosion protection coatings and apply touch-ups as needed.
5.1 - Preventive maintenance
- Our experience shows that, when used under normal operating conditions, plate heat exchangers have a service life of over
10 years. We advise against opening them too often.
- It is the user's responsibility to enquire about applicable environmental standards and prevailing legislation, particularly
regarding the frequency of checks and what to do in the event of a leak.
- Once a year, test the operation of all safety devices, check the condition of the insulation, look for signs of external corrosion
and test the pressure on the heat exchanger outlet.
