Heat Exchanger cleaning is the process of removing internal fouling, scale, residue and debris from the tubes within a heat exchanger to restore efficient heat transfer and reliable operation. Using high-pressure and ultra-high-pressure water jetting, deposits are removed along the full internal diameter of each tube without damaging the parent material. Cleaning can be carried out on both horizontal and vertical Heat Exchangers, using manual methods or automated systems such as Peinemann equipment, supported by flexi lances, specialist nozzles and certified Back-Out prevention devices that secure hoses and protect operatives during high-pressure operations in confined or restricted spaces.
This approach avoids harsh chemicals and abrasive mechanical methods while allowing the process to be tailored to different exchanger designs and tube materials. The use of automated equipment and engineered safety controls reduces operator exposure to risk, improves consistency and ensures compliance with industry best practice, particularly on larger bundles or shutdown projects. When carried out correctly, heat exchanger cleaning enhances performance, reduces energy consumption, minimises unplanned downtime and extends overall equipment service life.





Hydroblast provides specialist Heat Exchanger Cleaning using high-pressure and ultra-high-pressure water jetting to remove internal fouling, scale and debris from tube bundles. Regular cleaning is essential to restore efficient heat transfer, maintain consistent flow rates and prevent the loss of thermal efficiency that leads to higher energy consumption and operating costs. The controlled, non-destructive process also allows for visual inspection and integrity testing of tubes once deposits are removed, helping to identify thinning, pitting or damage before failure occurs.
Each project is carefully planned, starting with a site survey and risk assessment to determine the most effective cleaning method and pressures. Where appropriate, remote or automated systems are used to maximise safety, improve consistency and reduce downtime during shutdown periods. Wastewater is captured and managed responsibly, delivering a clean, efficient and environmentally considerate Heat Exchanger Cleaning service that improves performance, supports compliance and extends overall equipment life.
