Heat Exchangers generally fall into two categories within industry, either tube bundle heat exchangers or plate heat exchangers, with a further sub-category of having some heat exchangers as fully sealed units. Precision Processing is experienced at processing all types of heat exchangers and has successfully cleaned heat exchangers for cement works, chemical manufacturing, plastic component manufacturing, power generation, dairy industry, as well as other heat exchangers such as marine engine coolers and industrial lube oil coolers.

With our range of chemicals and techniques, we can offer a process that will best remove the process contaminants from your heat exchangers. Each overall process involves a series of process steps which build together to enable the successful refurbishment of the parts. We also can strip down and rebuild heat exchanger units at our dedicated processing facility. We can rebuild, re-seal and gasket units, as well as effect minor repairs and offer both pneumatic and hydrostatic testing of cleaned units.


What is heat exchanger cleaning?

Heat exchanger cleaning is the removal of fouling and scale build-up from the heat exchanger. Fouling and scale build-up prevent the heat exchanger from operating efficiently. Over time fouling and scale build-up can become so prevalent that the flow within the channels is restricted, thus reducing heat exchanger efficiency to a great extent. Depending on the type of heat exchanger in question, cleaning can be either mechanical cleaning, chemical cleaning or a mixture of both.

Where are heat exchangers typically used?

Heat exchangers are used in a range of process industries and are typically used to heat or cool various process fluids through indirect heating and cooling. As the range of industries varies, the range of fouling varies, but common uses of heat exchangers are in boilers where you will have rust and hard water scale fouling, oil cooling systems where you will have oil varnish fouling, and hot gas cooling systems where you will have combustion product fouling.


How often should heat exchanger cleaning occur?

Heat exchanger cleaning should be undertaken when the efficiency of your heat exchanger is reduced, which you typically notice by temperature drift of your process fluids, or when the flow of material through the heat exchanger reduces (in line pressure increases). Depending on your process and conditions you may not see either of these two effects, in which case your heat exchanger should be taken off line for inspection at least on an annual basis to ensure it is fit for purpose. 


What chemicals and equipment should be used when cleaning heat exchangers?

High pressure water jetting and wet blasting techniques are common methods to mechanically clean your heat exchangers. These methods are only useful when you can physically see and treat the surface of the parts which are fouled. Alkali or Acid processes are typically used to chemically clean your heat exchanger, although this should be undertaken by a specialist cleaning company who knows what they are doing.


How much does heat exchanger cleaning cost?

The cost of cleaning a heat exchanger is typically a fraction of the cost of replacement, and good maintenance and upkeep of your heat exchangers especially through routine cleaning, will ensure the heat exchanger is fit for purpose and running as efficiently as possible.

How successful/ useful is heat exchanger cleaning?

Routine cleaning of your heat exchangers maintains the efficiency in your process equipment, which therefore has an overall positive effect on your process. Almost all heat exchangers can be cleaned, some to a greater extent than others. Success of heat exchanger cleaning can be quantified by testing flow through the heat exchanger and comparing to manufacturers data, but also following cleaning when the unit has been returned to service, the efficiency can also be measured, thus giving a positive indication of success.
