Heat Exchanger Cleaning

Heat exchangers are used across various industries, including refineries, desalination plants, power generation stations, HVAC systems in food factories, and numerous other industrial facilities. These heat exchangers require regular maintenance and care to ensure high heat transfer efficiency. Timely and professional treatment protects valuable equipment and guarantees its proper and efficient operation.

Common Types of Heat Exchangers

Tube & Shell Heat Exchangers
Plate Heat Exchangers

Laur Engineering Ltd. has the expertise, equipment, and many years of experience in cleaning and maintaining heat transfer surfaces in heat exchangers at a high professional standard. By using one or more of the cleaning technologies available at Laur Engineering—whether high-pressure water cleaning, blockage removal, chemical cleaning, or a combination of methods—the result is restoring the heat exchanger to optimal operation while preserving the equipment itself.

Case Study – Cleaning a Heat Exchanger Clogged by Polymer

Problem: Severe clogging of a particularly hard polymer in the heat exchanger tubes. The client attempted to solve the problem using several technologies without success.
Solution: Hydro-dynamic cleaning using high-pressure water with specialized end tools, a dedicated high-pressure pump with high flow rates, and multiple specialized nozzles.
Benefit to the Client: The heat exchanger was restored to regular operation in the shortest possible time, improving performance and providing long-term energy savings.

Case Study – Cleaning a Graphite Heat Exchanger

Problem: Accumulation of deposits in a graphite heat exchanger. The goal was to perform efficient cleaning without damaging the heat exchanger itself.
Solution: Cleaning using dedicated technology and specialized end tools, including nylon cleaning brushes and a custom pump.
Benefit to the Client: The heat exchanger was restored to regular operation while preserving the structural materials.

Laur Engineering Ltd. performs controlled chemical cleaning of plate heat exchangers without disassembling the plates. This method is typically efficient and effective, and significantly faster compared to a full disassembly of the heat exchanger assembly.

During the cleaning process, laboratory tests (performed in a field lab) are conducted to ensure the protection of the structural metals and to limit the cleaning duration until the reaction is complete.

When a more thorough treatment is required, a full disassembly of the heat exchanger is performed using specialized hydraulic equipment. Each plate is then cleaned with high-pressure water, gaskets are replaced, and the heat exchanger is reassembled.

In both methods, inspections are conducted to ensure that the heat exchanger is clean and properly reassembled, guaranteeing optimal performance and operational safety.

Heat Exchangers – Essential Components in Industrial Systems

Heat exchangers serve as a central and critical component in many systems. Their use is widespread across various industries and applications. As their function requires contact with water (or another cooling fluid), lack of regular maintenance can lead to scale formation, sediment accumulation, and dirt buildup. To prevent these harmful factors from reducing system efficiency, heat exchangers must be cleaned periodically.

Due to the sensitivity of these components, it is highly recommended to entrust the cleaning process to a professional and experienced engineering company, such as Laur Engineering Ltd., which possesses the necessary equipment and advanced technologies to perform thorough and professional cleaning.

How Is Heat Exchanger Cleaning Performed?

For those new to the world of heat exchanger cleaning, it becomes clear that there are several techniques available, each based on advanced technology or the use of specialized chemical solutions. One of the most common and effective techniques is high-pressure water cleaning, which allows both internal and external surfaces to be cleaned, achieving a thorough and high-quality result.

When selecting a company to perform the cleaning, it is recommended to inquire about the specific methods and technologies they use and to gather as much information as possible to ensure the technique is effective. Some clients may have specific requirements regarding the preferred cleaning method, and it is important to choose a company that can meet those expectations.

How Heat Exchanger Cleaning is Performed

A heat exchanger is a critical component in industrial systems and facilities. Cleaning heat exchangers is essential across various industries, both for plate heat exchangers and shell-and-tube heat exchangers. Constant contact with water and liquids leads to the formation of dirt, scale deposits, oxides, and more.
Without periodic cleaning, heat exchange efficiency will suffer, impacting the performance of the entire system. These cleaning operations must be carried out by professionals with the necessary knowledge, experience, and equipment. Laor Engineering Ltd. performs industrial cleaning under the guidance of engineers who carefully assess the cleaning challenge and determine the most relevant and effective process. With Laor Engineering Ltd., you are guaranteed a professional team, rich knowledge, years of experience, specialized equipment, high availability, and courteous service.

High-Pressure Water Cleaning for Heat Exchangers

There are several methods for cleaning heat exchangers, with high-pressure water cleaning being one of the most effective. A powerful pump, with high pressure and flow rate, streams water through a customized nozzle; the water jet breaks down scale build-up and other deposits clogging the pipes, flushing the dirt out.
Cleaning heat exchangers with high-pressure water achieves excellent results with high efficiency and without the use of chemicals. Additionally, high-pressure cleaning is considered more environmentally friendly and cost-effective (lower operating costs compared to other methods). Please note: it is vital to perform the cleaning through professionals who know the systems and understand how to carry out this process without damaging the heat exchanger's structural materials.

Who Needs Heat Exchanger Cleaning?

Process industries, petrochemicals, power generation, water desalination, refining, and air conditioning all utilize heat exchangers. Periodic and professional maintenance of heat exchangers is essential for maintaining consistent output; therefore, ensure they are cleaned on time and at the appropriate frequency to preserve your expensive industrial equipment over the long term.

Laor Engineering Ltd. possesses the equipment and technological means required for maximum results. For example, specialized cleaning systems based on water pressure or chemical cleaning remove dirt, with an emphasis on scale deposits and oxides that accumulate inside the pipes. Laor Engineering's team of engineers knows how to offer a high-quality, precise, and customized solution for every industrial cleaning job. Contact us for more details.
