Heat exchangers

Service and maintenance of industrial heat exchangers

For industrial heat exchangers to maintain their optimal performance as well as their lifetime, regular servicing and careful maintenance are required. As these components play a central role in heating, cooling and process systems, it is important to keep them in good condition to avoid downtime, reduced energy efficiency and unnecessary repair costs. By implementing a structured maintenance program, companies can ensure reliable and cost-effective production.

Cleaning and deposit control

One of the most common causes of reduced performance in a heat exchanger is scale or deposits. Lime, dirt, oil residues and other particles can accumulate on plates or tubes over time, reducing heat transfer and increasing energy consumption. Regular cleaning is therefore essential to maintain efficiency.

Depending on the type of heat exchanger and operating conditions, different cleaning methods can be used:

• Chemical cleaning – dissolves limescale, corrosion products and other deposits without damaging the material.
• Mechanical cleaning – Mainly used for shell and tube heat exchangers where high pressure flushing or brushes can remove deposits.
• Ultrasonic cleaning – An effective method to clean heat exchanger components at a microscopic level.

Inspection and preventive maintenance

Regular inspections of the heat exchanger are important to detect potential problems before they lead to serious malfunctions. Some of the critical points to check include:

• Leak test – Detects small cracks or defects in gaskets or plates.
• Pressure test – Ensures that the heat exchanger can withstand the loads it is subjected to in operation.
• Plate inspection – Identifies damage or wear to the plates in plate heat exchangers.

Planning and carrying out these inspections regularly can prevent unexpected downtime and reduce the risk of major repairs.

Replacement of wearing parts

Gaskets, plates and other components of a heat exchanger are exposed to high temperatures, pressures and chemical loads, which over time lead to natural wear and tear. To ensure continued operation, these parts should be replaced when necessary. Using high-quality spare parts from a reliable supplier is essential to maintain performance.

Optimization and energy efficiency

A well-maintained heat exchanger not only helps keep operating costs down but also contributes to more sustainable and energy-efficient operations. By monitoring temperature differences, flow rates and pressure conditions, areas for improvement can be identified and the system adjusted to achieve maximum heat recovery.
