Chemical cleaning is a highly effective method for removing deposits, scaling, and corrosion products from heat exchangers. The process uses specially formulated cleaning agents that circulate through the equipment to dissolve unwanted residues without causing damage to the base material.​

Depending on the fouling type and material of the heat exchanger, different chemical solutions are applied, such as acidic, alkaline, or neutral detergents. ​

This method ensures thorough cleaning of even hard-to-reach areas inside the equipment, where mechanical methods may be limited.

Kelvion provides a full-service offering for heat exchangers. Components are checked against new equipment standards, allowing for sustainable reuse and environmental benefits. Depending on the damage, Kelvion delivers the right solution – from thorough cleaning to retubing or part replacement. If, for example, cleaning is no longer sufficient due to excessive fouling and corrosion, we can go straight to the next level and, for example, carry out any necessary retubing or replacement of parts.​

Kelvion’s recoating service restores and protects heat exchangers exposed to fouling, corrosion, or aggressive operating conditions. After a thorough inspection and surface preparation, we apply advanced protective coatings that significantly improve resistance against corrosion and chemical or biological attack. ​

Retubing is a proven method to restore the performance and extend the service life of heat exchangers. Over time, tubes can suffer from fouling, corrosion, erosion, or mechanical damage, leading to reduced efficiency or leakage. During retubing, the old tubes are carefully removed, tube sheets are cleaned and prepared, and new tubes are installed, expanded, and sealed to OEM specifications. This process restores the unit to like-new condition, improves reliability,and minimises the risk of unplanned downtime – all without the need to replace the complete bundle or heat exchanger. ​

Our Condition Analysis service for finned tube heat exchangers provides a comprehensive assessment of the condition of your heat exchangers. This includes leak tests as well as a detailed examination and assessment of the fin side and the tube side. Deposits and corrosion are analysed in depth.
Optionally, further analyses such as water testing, the targeted assessment of corrosion issues, and endoscopic inspections to identify fouling, corrosion and erosion can be carried out.

Spare parts and replacements play a crucial role in maintaining equipment reliability, performance, and longevity.​

When your equipment reaches the end of its lifecycle or no longer meets your operational requirements, our replacement service provides a seamless transition to a new, optimised solution.​

An effective spare parts management strategy ensures minimal downtime, optimised maintenance schedules, and cost-efficient operations. By keeping critical spare parts readily available, companies can respond quickly to unexpected failures and maintain continuous production. Additionally, using genuine or high-quality replacement parts helps preserve system efficiency, safety, and compliance with technical standards.​

Upgrading or replacing heat exchangers improves energy efficiency, reliability, and system performance. Modern designs enable higher thermal efficiency,reduced pressure losses, and better integration into existing systems.​

When upgrades are no longer sufficient, replacing aging heat exchangers provides a sustainable long-term solution, lowering maintenance needs and supporting current efficiency and regulatory requirements. Both options represent a strategic investment in operational performance and energy efficiency.​
