Mechanical cleaning of heat exchangers covers a wide range of measures to maintain performance and reliability. It includes internal cleaning – either on the tube side (carried out at the factory or directly on site) or on the housing side (at the factory).
Depending on the application, high-pressure cleaning or brush cleaning of the tube side is applied to remove deposits effectively. By cleaning both the inner and outer sides, the thermodynamic performance of the equipment can be significantly improved. This process not only optimises efficiency, but also contributes to corrosion protection, ensuring long-term durability and safe operation of your heat exchangers.
Key Service Solutions
Our cleaning machines ensure efficient maintenance of both shell & tube and air-cooled heat exchangers. For air-cooled exchangers, a pumping skid supplies water under pressure to the bundles, while a semi-automatic unit with manifold and spray nozzles cleans the finned surfaces. This process removes external fouling, safeguards performance, and reduces downtime.
For our Air Cooled Heat Exchangers we offer a special service. By carrying out an Energy Audit on-site, our service engineers will identify how the heat exchanger is performing and recommend any repairs or upgrades needed to optimise it.
By e.g. retrofitting parts with better, more efficient, equipment, the production viability of the heat exchanger is assured. Any bottlenecks constraining operation that were identified in the audit will be removed and efficiency improved, which in turn leads to savings on energy and costs, increases the MTBF and can reduce noise and vibration.
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.
With the Kelvion Tube Liners & Shields technology you can easily repair and restore damaged heat exchanger tubes. Whether you are dealing with leaks caused by localised erosion/corrosion at the tube ends or throughout the entire tube length, Kelvion’s Shields/Seals and Full-Length Tube Liners can extend the life of your heat exchangers to avoid costly downtime or bundle replacement. The advantages are: emergency repair services on failed equipment in-situ, long-term reliable, uninterrupted production on critical heat exchanger as well as proven and effective repairs for problems related to inlet and outlet tube ends with I.D. or O.D. damage.
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.
