OptimICE®
Overview
OptimICE® is an advanced slurry ice technology that replaces conventional flake ice. It uses seawater or saltwater to create liquid slurry ice that quickly cools fish to below 0°C / 32°F, ensuring freshness and extending shelf life throughout the cold chain.
Rapid cooling of the catch is key
As soon as a fish is caught, its decay begins and the sooner it gets refrigerated, the less bacteria will grow, shelf life will be prolonged and maximum quality maintained.

Revolutionizing fish preservation
The OptimICE® liquid Ice system cools the fish down to below 0°C / 32°F in less than one hour. Using traditional flaked ice, it takes around fifteen hours to reach the same temperature.
It is a recognized fact that treatment and cooling speeds are the most important in maintaining fresh fish quality. The key to increasing the quality of fish is rapid cooling, thus reducing microbial and bacterial formation.
Numerous studies have been performed on the cooling systems and all show similar results. The graph above is from Seafish Scotland. Matís, the Icelandic Food and Biotech research institute and the University of Akureyri as well as the International Journal of Refrigeration etc. have also researched slurry ice cooling and published similar results.

Fresh Product From Sea To The Consumer
The rapid and efficient cooling of the catch ensures the freshness and maximum quality of the product. The cooling never ends when the fish is in transport onshore. Even though cooling in a trailer fails, the cooling of the fish doesn’t stop because of OptimICE®.
The fish can finish the journey across the country and be complete and in top condition all the way, due to OptimICE®. The ice-less sub-chilling solutions are, on the other hand, very sensitive in transport.

Unique features
Unlike conventional ice-based systems, OptimICE® ensures a consistent and reliable temperature (-0.5°C / 31.1°F), which prevents the fish from freezing while maintaining maximum freshness.
This technology offers a significant advantage over traditional cooling methods in both performance and sustainability.
