Full effect with zero chemicals
The lice have a low level of tolerance for sudden changes in temperature. This fact is exploited by the Thermolicer where the fish are bathed briefly in lukewarm water. The lice die and fall off the fish, after which they are collected and destroyed.
The Thermolicer is a machine for commercial scale dip or bath treatment of fish. A sudden rise in water temperature is a well-known method of killing lice. The Thermolicer is developed to be able to bathe the fish in temperate water for a short period.
In practice, the Thermolicer is a water trap where the fish are constantly moving in the tube. This ensures that the fish do not come into contact with moving parts or are given space to accelerate and possibly hit a wall or an edge during the process.
The fish are crowded and pumped into the machine where it passes through the processing loop in 25–30 seconds. The treatment water holds 28–34 degrees depending on ambient sea temperature. The treatment water is filtered, aerated, oxygenated and reused in the system.
- Fish enters Thermolicer after pumping.
- Water separation.
- Sea water is filtered and released.
- The fish is exposed to lukewarm water.
- Treatment loop.
- Water surface.
- Water separator for treatment water.
- Fish exits the system.
- Heated water is circulated to water tank for filtration, aeration and reheating.
- Treatment water is pumped back to the treatment loop.
NB. The water treatment system is not shown.
The Thermolicer can be fitted on board service vessels, wellboats and barges. Fish are collected and pumped through the Thermolicer and then back into the same pen, or into an empty pen. Along with the Thermolicer, you receive training and recommendations to ensure that you are able to treat the fish when necessary rather than being dependent on third parties.
A standard Thermolicer is positioned in a 25 foot container. The length of the water trap is 22 meters and it has a capacity of up to 90 tons per hour. The actual capacity will vary somewhat depending on temperature, the size of the fish, the fish pump and the rate of crowding of the fish.
The Thermolicer is a patented method of delousing fish in a water trap. The capacity of a standard Thermolicer is limited by the length and breadth of this water trap. ScaleAQ can also customize treatment loops. This ensures that you can achieve a significantly higher capacity (tons/hour) per line and that the treatment loop can be adapted to suit most vessels.
