Vacuum CO₂ stripper – enhanced N₂ and CO₂ stripping
Overview of production – central location with short distances
Flexible production – adjustable tank sizes to secure optimal density
High turnover – up to two tank volume through RAS per hour
Prepared for additional features – hydrogen peroxide injection, protein skimmer with ozone and additional oxygen injection
RAS2020 – a cost-effective grow out system
