Description

Service for Plate Heat Exchangers

WELDED PLATE HEAT EXCHANGERS

Regular inspections of your heat exchanger’s performance allow preventative measures, including mechanical cleaning, CIP and welding repairs, to be taken to minimise the risk of unscheduled and costly downtime. They also help to extend the lifecycle of the equipment. In the event of failure, our service engineers will assess any damage, carry out tests and advise on the best solution, quickly and efficiently.

Thermal 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.

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 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.

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.
