FReE - Kurita's Fouling Removal Efficiency Program

Online Cooling System Cleaning Technology

Innovative Solutions for a Better World

At Kurita, we create shared value with customers and the environment. That’s why we developed our Value+ product portfolio, which aims to enhance productivity while reducing the total cost of operations (TCO) and supporting sustainability goals.

Our range of technologies, products, and services effectively minimizes water, waste, and energy consumption while also lowering carbon emissions.

FReE Concept

Increase heat transfer of your cooling system without plant shutdowns

REMOVE

Different types of deposit online

PROTECT

The whole water circuit system from corrosion

AVOID

Shutdowns & safe cleaning cost

COMBINE

With other actives or treatment programs

Fouling of cooling water system generates energy losses

An optimal heat transfer is the most important point in every water-cooled process.

Scale, corrosion, and biofouling negatively affect the heat transfer. That is why, cleaning is a “must”, because it minimizes the microbiological risks, reinstating the system efficiency.

Apply FReE and get rid of any kind of deposit

Kurita has developed the Fouling Removal Efficiency application, where a total cleaning is performed during operation, without being corrosive and with no generation of waste. We are committed to developing solutions which help both our customers in an environmentally friendly approach.

FReE achieves 100k €/y savings by avoiding downtime for cleaning in a Coke Plant in France

Big scaling in the quenching tower of a coke plant was causing a strong reduction in water flow rate with a high risk of blocking pipes. Scaling speed was >3cm/year with areas with more than 10cm thickness already, risking a pipe blockage, even regular cleanings, and reinforced maintenance. A total stop of production seemed inevitable. After 5 months of application of FReE! most of the scaling deposits were removed and the plant stoppage was prevented. 100k€ savings/a and Energy efficiency improved +30%

FReE increased 50% the flow rate in the water sealing unit of a steel plant

The water sealing pipelines of a major steel plant from Europe presented hardness deposits that were causing a strong negative impact on the production, nearly getting irreversible clogged. The flow rate was down to 15m3/h which was not enough to satisfy the cooling needs. 1 year after FReE! application the flow rate was recovered by 50% avoiding a very complex cleaning process for the plant and maintaining the production active all the time. Savings for the customer were 500k€.
