Heat exchanger maintenance for industry and commerce
Plate heat exchanger service. Greater efficiency, less downtime, longer service life – thanks to heat exchanger maintenance.
Full performance through professional heat exchanger maintenance
Is your system no longer working as efficiently as it used to?
Increasing differential pressure or reduced performance are clear warning signs and a reason to take action!
API Heat takes care of all maintenance and cleaning of your plate heat exchangers—regardless of manufacturer, documented, and with certified quality.
Our service technicians detect deposits, material wear, or leaks at an early stage – and restore your system to full performance. Hydrostatic water pressure testing (integrity test) included.
On request, we also clean shell and tube heat exchangers in composite systems.
Original SIGMA spare parts ensure a perfect fit and fast availability.
Why regular heat exchanger maintenance is so crucial
✅ Permanently reduce energy costs – through maximum heat transfer and lower pressure loss.
✅ Your system runs more reliably and for longer – maintenance protects against breakdowns and expensive consequential damage.
✅ You gain planning security – with fixed maintenance intervals, clear documentation, and fewer surprises during audits.
✅ You benefit from tested quality – original OEM spare parts ensure a perfect fit and long-lasting performance.

Industries & Applications – Your process, our experience
Chemicals & Pharmaceuticals
Sensitive media require maximum process reliability.
Regular heat exchanger maintenance and cleaning ensure stable temperatures, prevent media mixing, and reduce energy losses—for safe, auditable production processes.
Food & Beverages
In food and beverage production, hygiene determines product quality. Professional cleaning of plate heat exchangers removes grease, sugar, and protein residues, keeps heat output and efficiency constant, and supports IFS and HACCP-compliant audits.
Energy & Utilities
Whether district heating networks, combined heat and power plants, or power plants—reliable heat exchangers mean predictable energy flows. Regular maintenance prevents efficiency losses, reduces downtime, and measurably lowers operating costs.
Marine & Offshore
High exposure to salt, biofouling, and vibrations?
Targeted cleaning and seal testing ensures the cooling performance of your systems and prevents corrosion and failures—for operational safety at sea and on offshore platforms.
Paper, metal & process industry
Deposits, solid particles, and aggressive media reduce heat output. Reconditioning plate heat exchangers keeps temperature profiles stable, reduces energy consumption, and significantly extends system operating times.
Frequently asked questions
How long is the service life of heat exchangers?
With consistent maintenance: 10–20+ years, depending on the medium & temperature.
How often should a plate heat exchanger be serviced?
As a rule, maintenance is recommended once a year – depending on the medium, temperature, and operating hours. For heavily loaded systems (e.g., chemicals, food, energy), a shorter interval may be advisable.
What to do in case of leakage?
Stop the system, check the pressure, call service.
Having a heat exchanger repaired—what are the costs?
The cost of repairing a plate heat exchanger depends heavily on its condition, size, and medium. Talk to us – we will find out what needs to be done and then estimate the costs.
Heat exchanger repair vs. complete replacement – what should I do?
In many cases, repair is significantly more economical than complete replacement, as existing components can continue to be used.
Do you offer chemical cleaning using the CIP process?
No – we rely on mechanical cleaning followed by a water pressure test to protect the material and seals.
What documentation will I receive?
Cleaning & pressure test reports, photos, parts lists, maintenance recommendations (digital or as PDF).
