Heat exchanger fouling
Posted: Wed Dec 28, 2016 6:47 am
We have successfully installed devices on board two well known cruise ships that have almost totally eliminated bio-fouling within their engine heat exchangers. Requiring no attention by the crew, other than a simple 5 minute cartridge change once a month, the device eliminated the need for back flushing. Previously back flushing weekly, after 24 weeks of no back flush, when opened for examination, there was only one bio-foul point!
The system installs simply and infuses a few minutes each hour low dose iodine vapor as bubbles which doesn't allow for the formation of bio-foul. It also does not impart excessive biocides to the water stream and can improve a fouled exchanger in an emergency. Having undergone numerous studies by the US Navy, it reduced hard hull fouling by more than 75% and increased the time between heat exchanger cleaning by 300%. Is there interest in hearing more about this?
