Features

Corrosion and water resistant:
All components are stainless steel, high strength polymer, or aluminium and where electrolysis might be an issue, protective coatings and coverings have been applied to ensure electrical isolation and corrosion resistance.

High velocity stunning:
The captive bolt has been designed to more effectively provide a consistent instantaneous, irreversible stun. This has been achieved by providing greater velocity and less momentum causing greater shock to the fish's brain without causing inefficient penetrative damage. The SI~5 is effective with only a single hit.

Reliability:
The captive bolt has also been designed so that it cannot slip down and returns to the same position each time thereby delivering all blows with equivalent force.

Size Range:
The size and species range has been extended to cover fish in the range 500g to 14.0kg.

Low maintenance and service costs:
Constructed for durability in the Marine Environment. All components are modular and can be replaced in minutes even in the field. Pneumatic controls are located in a purpose built protective casing. A full time oiler in incorporated in each machine.

Self-feeding delivery and flow through design:
The SI~5 feed table (Patent Pending) draws fish to the stunner inlet channels while the SI~5 trigger system allows the fish to actuate the stunner and pass right through.

In the automated setup, one operator can now control the fish pump as well as up to five SI~5 machines producing up to 75 fish per minute.

As a benchtop unit, the new SI~5 is much faster than other benchtop stunners due to its flow through system. This means that a sudden surge of fish can now be handled with ease, and flow is maintained on the harvest line. Fish are therefore handled quickly and stress is reduced to an absolute minimum.

The SI~5 is also easy on the operator with the one-way flow system meaning no fish can escape or bypass the stunner and only one action is needed to operate the stunner. When fish farmers and processors have seen the SI~5, it quickly becomes apparent that this machine is the natural evolution from earlier benchtop stunners that they have been asking for.
