- In general the box cooler system is a maintenance free system for most applications. However depending on the area of sailing and on several operational conditions biological fouling can occur.
- The type of organism most responsible for biological fouling on box coolers is mussels.
- Biological fouling can appear on coated as well as un-coated box coolers.
- In case of severe biological fouling the thermal performance of the box cooler is deteriorated.
- To avoid this biological fouling an anti fouling system is recommended.
- When some bio-fouling has settled on the box cooler, the negative effect on the thermal performance is hardly noticeable. Only when the box cooler is totally covered with bio fouling, causing a blockage of the flow between the tubes, the thermal performance will be influenced. Due to the external coating on the tubes of the GEA Bloksma box cooler, bio-fouling and other deposits cannot cause the so feared under deposit corrosion.
