Service
Service & support
We recalculate existing heat exchangers thermodynamically, clean and repair gasketed plate heat exchangers and shell-and-tube systems, and train your operating personnel. We supply spare parts for ETS units and common third-party makes from stock in Switzerland.
Engineering & sizing
Has your process data (mass flows, media, temperatures) changed? We recalculate your existing heat exchanger thermodynamically and check the optimization potential for increasing duty or reducing pressure loss.
Cleaning & repair
We carry out professional, complete chemical (CIP) and mechanical cleaning of gasketed plate heat exchangers and shell-and-tube systems, including non-destructive crack testing of the plates.
Spare parts service
We supply replacement gaskets (NBR, EPDM, Viton) and replacement plates for ETS units as well as for third-party makes such as Alfa Laval, GEA/Kelvion, APV/SPX and Sondex, directly from stock in Switzerland.
Training & commissioning
Training for your operating personnel on the optimal operation of thermal systems, on avoiding water hammer (cavitation), and on carrying out simple preventive maintenance steps.
Maintenance intervals by product type
Guideline values for industrial use. A closed heating water circuit often runs for years without cleaning; in dairies (milkstone formation) or with raw water cooling, the intervals are significantly shorter.
Brazed heat exchangers
Closed systems (HVAC, refrigeration), compact design without gaskets.
- Inspection: visual check annually
- Cleaning: CIP flushing (every 3-5 years)
- Replacement: full replacement in case of leakage
Gasketed heat exchangers
Industry, chemicals, food. Modularly expandable, elastomer gaskets.
- Inspection: visual check semiannually
- Cleaning: mechanical/CIP (1-3 years)
- Replacement: gaskets (3-7 years)
Shell-and-tube heat exchangers
High pressure, high temperature, steam, aggressive special media.
- Inspection: crack testing/pressure test (5 years)
- Cleaning: high-pressure lance (1-3 years)
- Replacement: retubing as needed
Service and

Frequently asked
questions
How often do heat exchangers need to be cleaned?
That depends largely on the medium. While closed heating-water circuits often run for years without cleaning, heat exchangers in dairies (milkstone formation) or those used to cool raw water must be cleaned regularly. We determine the optimal cleaning cycle based on your pressure-loss monitoring.
Does ETS also supply spare parts for other manufacturers’ equipment?
Yes. We supply plates and gaskets from almost all well-known manufacturers (such as Alfa Laval, GEA/Kelvion, APV/SPX or Sondex) from stock in Switzerland. We carry replacement gaskets in NBR, EPDM, and Viton.
How does thermal optimization work?
You provide us with the current operating data. Our project engineers simulate the exchanger in our documented in-house software, which can also reliably calculate special gas and liquid compositions. Optimization modules enable additional material and cost savings. Often we can significantly increase efficiency with a different plate corrugation pattern or a modified bundle layout, thereby saving material and cost without having to replace the casing or the piping.
