Ace Aquatec Humane Stunner Universal (HSU)

Q: How does in-water stunning actually work?

Fish slide straight from a short de-waterer into the stunner water, where an electric field renders them unconscious immediately, before they are moved on to bleeding.

Q: What throughput does the standard unit handle?

The standard build is rated at 20 tonnes of fish per hour, and higher capacities are available as a bespoke build.

Q: How long are the fish in the stunner?

About 20 seconds — a dedicated water pump controls the flow through the stun tube so transit time stays consistent.

Q: Can it be used in seawater?

Yes — the stunner is built for either fresh water or salt water, so it suits both marine harvest and land-based processing.

Q: Where can it be installed?

In a land-based processing plant, on a boat or raft for dead-haul harvesting, or inside a container, with the stun tube straight or bent and either floor or wall mounted.

Q: Does stunning affect carcass quality?

No — the stun field shape and the smooth flow of fish through the tube give long pre-rigor times without internal haemorrhaging.

Q: How do I get a price?
