Service for Plate Heat Exchangers

Gasketed Plate Heat Exchangers

Even the highest performing plate heat exchangers are subject to wear and tear. Regular monitoring and servicing will keep equipment running effectively for longer and avoid costly and disruptive unscheduled down time - periodic inspections will extend the lifetime. The Kelvion Service includes performance auditing, reconditioning, resizing and leakage testing – all to the highest standards. We believe that installing new gaskets to the highest standards are crucial for extending their service life. Our ten-step process, which leaves nothing to chance, includes inspections, replacing old gaskets, cleaning and dye testing, to ensure a first-class result every time.

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.

Cleaning Machine

Our cleaning machines ensure efficient maintenance of both shell & tube and air-cooled heat exchangers. For shell & tube units, the system cleans the water side, removing chalk, rust, and corrosion products, and is suitable for copper-nickel alloys, stainless steel, titanium, and brass.

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.

Reconditioning Process

Our 10-Step-Process for installing new gaskets equals a first-class result. First, we inspect the equipment before removing the old gasket and cleaning the plates. This is followed by a dye test and second inspection, removal of the dye residue, cleaning the gasket groove and final plate inspections.
The new plates are then fitted and quality checked. This plug and play, ‘problem-free’ solution, using original spare parts, ensures that plate heat exchangers will return to their optimal performance and extend their lifetime, giving you peace of mind.

Hydrogen Leakage Test

Plate heat exchangers can sometimes be exposed to external influences that may cause microscopic leaks. With our innovative leakage test we can track down any material fatigue by feeding a hydrogen/nitrogen mixture into the closed plate heat exchanger on the water side. This is faster and more efficient than conventional methods and can also be used as a preventative tightening test.

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, optimized solution.

An effective spare parts management strategy ensures minimal downtime, optimized 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 andsupporting current efficiency and regulatory requirements. Both options represent a strategic investment in operational performance and energy efficiency.
