Heat exchanger cleaning
A cleaned heat exchanger performs better. Guaranteed
Maximum performance. Minimal downtime. Just the way your process needs it.
Heat exchangers are indispensable for cooling, heating and efficiency in any production process. But after thousands of operating hours, fouling occurs: scale, sludge, oil, salt, product residue or even biological fouling.
Result of dirty heat exchangers:
The consequence when heat exchangers are not cleaned in a timely manner are not tender:
decreasing capacity
increased temperatures
more energy consumption
risk of failure
shorter life
At Blue Orange, we keep heat exchangers clean, strong and reliable – with chemical cleaning for heavy deposits and ultrasonic cleaning for deep, delicate soiling.
For industry, shipping and agricultural businesses that cannot and should not stand still.
How will we clean your heat exchanger?
Maintenance and repair is more than cleaning and replacing.
It’s about thinking ahead, identifying, improving and taking responsibility.
Therefore, our method consists of four fixed steps:
For heavy scaling, lime, silt, rust and water-side deposits.
Suitable for:
plate heat exchangers
shell & tube heat exchangers
condensers & evaporators
water/glycol systems
industrial coolers
Advantages:
safely dissolves hard deposits
quick result
ideal for industry and agriculture
can be done on location and in our workshop
For deep, hard-to-reach soiling in fins, fins and small openings.
Suitable for:
charge air coolers
oil coolers
air coolers
marine coolers
delicate plate changers
Advantages:
extremely thorough cleaning
ideal for salt, silt and biofouling
perfect for marine applications
always in controlled ultrasonic bath
Heat exchanger cleaning: here’s why it’s necessary:
Heat exchangers always pollute. But if it grows too far, the whole process becomes unbalanced.
Pollution leads to:
efficiency losses (in practice we see losses as high as 40% for severely fouled heat exchangers)
higher energy costs
pressure differential / reduced flow
rising engine temperatures (maritime)
deterioration of plates, tubes or fins
breakdowns and unplanned downtime
Cleaning is not a cosmetic procedure – it is crucial process optimization.
With the right method (chemical or ultrasonic), we restore the full capacity of your heat exchanger.
Sectors
Recognizable for your industry?
How do we proceed?
Every project at Blue Orange goes through the same clear structure. So we work quickly, precisely and completely transparently, from intake to completion.
Analysis & inspection
We begin with a focused inspection of the heat exchanger.
We check fouling type, flow, any leaks, and determine which cleaning method will provide the most efficiency.
Cleaning (Ultrasonic or Chemical)
Based on the diagnosis, we choose the optimal approach:
ultrasonic for deep, delicate or marine soiling
chemical for lime, sludge or water side scale
The heat exchanger is completely cleaned according to strict safety and environmental procedures.
Recovery &
Test
After cleaning, we retest the heat exchanger:
pressure test or leak tightness test
visual inspection
performance recovery compared to the initial situation
That way you know exactly how much capacity has been recovered.
Delivery & Reporting
You will receive a clear report with test results, photos and a recommendation for preventive maintenance.
If required, we also provide transportation or planning for another round of cleaning.
What cleaning method does your heat exchanger need?
Blue Orange inspects, tests and then chooses the cleaning that provides the greatest return – never standard, always customized.
| Situation | Best method |
|---|---|
| Lime / scaling | Chemical |
| Waterside fouling | Chemical |
| Salt deposits / seawater residues | Ultrasonic |
| Fine sludge in fins | Ultrasonic |
| Biofouling / fouling | Ultrasonic |
| Severe corrosion deposit | Chemical + inspection |
| Oil contamination | Both (analysis dependent) |
What will your heat exchanger cleaning do for you?
up to 40% more efficiency
lower energy costs
longer service life (3-7 additional years)
cooling capacity fully restored
fewer failures and less downtime
improved engine performance (marine)

Request heat exchanger cleaning
Want to keep your heat exchangers in top condition?
Or is there an acute outage that needs to be resolved immediately?
Get in touch – our specialists are standing by.
We determine that during the inspection. For scale, rust and water-side fouling, we usually choose dry cleaning. For fine contamination in fins or fins (as in CACs and air coolers), ultrasonic is almost always the best choice.
No. We always choose the safest method for the type of material and contamination.
Ultrasonic and specialty cleanings remove dirt deep into plates and fins without damage to the metal.
We test each exchanger afterwards to confirm this.
This varies per situation, but in practice we see that a cleaned heat exchanger delivers 20-40% more capacity than a dirty one. We measure this afterwards with a performance measurement.
Yes. Dry cleaning can often be done on site. Ultrasonic cleaning is always done in our workshop because an ultrasonic bath is required.
Small plate exchangers are often completed within one business day. Larger shell & tube, marine or industrial coolers may take 1-3 days, depending on contamination and required testing procedures.
We dispose of all residues in an environmentally friendly way and according to applicable laws and regulations. You don't have to make any arrangements yourself.
Yes, but with severe corrosion or cracking we sometimes recommend overhaul or repair. We discuss this during the inspection and always show the underlying damage.
On average, once a year. In marine and heavy industrial environments it may be needed more often. After the cleaning, you will receive a customized recommendation.
Not always. We can ultrasonic clean small exchangers as a whole, but for fixed installations in industry or shipping, disassembly is sometimes necessary.
Cleaning does not solve leaks, but it does make leaks visible. If damage is found, we can repair or replace immediately.
