Fouling Cure
Fouling Cure
FoulingCure – is an add-on cleaning system to any existing plate heat exchangers. Cleaning during operation and full load – without any energy loss or operational downtime. We provide a revolutionary and patented technology cleaning with high velocity flow that fits any exchanger brand. Installing FoulingCure on your heat exchanger removes fouling immediately and maintain 100% heat transfer performance. FoulingCure also integrate Backflush and CIP modules when needed
There are several different types of fouling, depending on the type of liquid used for the energy transfer and the material used in the plate heat exchanger
- Particulate fouling by particles suspended in water or gas
- Biofouling is undesirable accumulation of micro-organisms
- Chemical fouling is the reaction on contacts with process fluids and heat transfer surface
- Solidification fouling is when a component of flowing fluid “freezes” onto the heat transfer surface
- Corrosion fouling is created by corrosion of the substrate like iron oxide from carbon steel
- Precipitation – Scale formation due to dissolved substances like calcium carbonate or salts
FoulingCure Concept – Cleaning during full operation and load – with no down time
Background for the development – The FoulingCure technology has been developed and patented based experience within the plate heat exchanger industry. Wanted to find a solution to prevent the fast deterioration of heat exchangers’ effectiveness, which can be a very expensive in energy loss and time-consuming maintenance task.
The decline in effectiveness explained – A plate heat exchanger requires a large heat transfer area and a low flow rate to procure high performance. In fact, a plate heat exchanger is the piece of equipment in a process line with the lowest flow rate. Therefore, fouling can easily settle and accumulate.
At the same time, the plate heat exchanger is designed to create liquid turbulence – which ensures optimal transfer of energy via the plates. In addition, the turbulence further ensures that fouling are washed off the plates – also known as the self-cleaning effect.
The self-cleaning effect is a function of the turbulence, and the turbulence increases exponentially to the liquid flow rate. By doubling the flow rate, the self-cleaning effect increases by 4. When tripling the flow rate, the self-cleaning effect increases 9 times, etc. In other words, FoulingCure uses the flow effect to keep the heat exchanger free from fouling.
The FoulingCure cleaning system – Based on an increase in the flow rate of 200–300%, the FoulingCure system secures an increase in the self-cleaning effect of 400–900% – leaving the plate heat exchanger as good as new in terms of performance after every cleaning cycle. The increased flow rate is provided by an external pump. The FoulingCure rinsing head covers 1–3 plate channels at a time.
Your advantage – The cleaning process is performed while the plate heat exchanger is in full operation – without any energy loss or operational downtime. We simply flush the plate heat exchanger with regular intervals and keep it clean for years before carrying out the next full service.
