Kelvion Service

Service for Box Coolers

The Kelvion box coolers are robust and built to last, but the anti-corrosion coatings may degrade over time. This can lead to a buildup of unwanted biological organisms, such as seaweed, algae and bacteria, that will restrict the flow and in turn lowers the thermal performance of the cooler – which affects the operation of equipment connected to the box coolers. The Kelvion refurbishment program will ensure a long service life and high availability. The Service includes sea chest inspections, cleaning, recoating and repairs to keep box coolers running efficiently.

Key Service Solutions

Mechanical Cleaning

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.

Chemical Cleaning

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.

Thermal Cleaning

Thermal Cleaning is the process of thermal decomposition of organic materials at elevated temperatures, in an inert atmosphere without access to oxygen.

This allows us to perform recoating to OEM specification again, extending the coolers life cycle.

Recoating

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.

Standard Retubing

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.

Spare Parts

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.

Upgrades & Replacements

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.
