Pre-designed.
Plug and play.

Ontec delivers pre-designed tanks and production modules for land-based aquaculture — to upgrade an existing site, grow in stages or build a complete facility. Simpler planning, fewer interfaces, a shorter build and lower cost.

What we deliver

Start where your site is.

Pre-designed tanks and modules instead of one complex facility designed from scratch, corner to corner. Simpler planning, fewer interfaces, a shorter build and lower cost.

Services
Two system types

Parametric hybrid or RAS.

Water is treated at each tank or group of tanks, not in one central plant. Choose a system type to see how the water moves.

Why it matters

Simplification and safety by design.

Conventional plants pipe every tank to one central treatment building, through large pipes in the ground. Ontec treats water at each tank or small group of tanks, so little more than floor drains goes under the floor.

Floor drains

Simpler civil works

No large consolidated pipes in the ground, with the flanges and valves they bring, and far less concrete and ground work.

Clean split

Clear interfaces

A simple boundary between building and civil works and the process plant installation.

Per tank

Biosecurity

Tanks don’t share water. In a facility built on IPUs, each tank stands alone; in modules, water is shared only within the module.

60–70 %

Lower capex

Of the industry-average capex per kg, thanks to simpler piping and concrete, a standardised design and a better area-to-volume ratio.

Proven on our own fish.

Ontec’s system was proven at Ontec Academy, on our sister company OFS Måløy’s site on the strait, licensed for 15,000 tonnes. The group farms there itself, so every design choice is tested by people who carry the risk.
