Commercial Oxygen Demand & LOX Cost Calculator
Oxygen is life-support and typically 3–10% of commercial OPEX. This sizes total daily O₂ demand from steady-state biomass and species-specific respiration, then converts it into liquid oxygen (LOX) tonnage and annual cost at a delivered LOX price.
Scenario modelling
Flexes temperature, safety margin, transfer efficiency and LOX price.
Calculator inputs
Peak in-water biomass, not annual harvest.
O₂ demand rises ~10% per 3 °C.
LOX cones ~90%. Aeration ~15%.

Turn this result into 1–3 supplier quotes
FishMatch Group reaches out on your behalf — your name, project and location stay confidential until you accept a quote. No sign-up, no listing fees, buyers never pay.
How supplier matching works
- 1. Private brief. Your spec goes only to manufacturers we have selected for the right category, capacity and export experience.
- 2. Confidential outreach. Suppliers see the technical spec — not your name, company or exact location — until you accept a quote.
- 3. 1–3 comparable quotes. Typically within 5–10 business days, aligned on scope so you can compare like-for-like.
- 4. Financing intro (optional). If needed, we introduce your project to a financing partner. No fee to buyers.
Notes
- Below ~5 kg O₂/day, aeration wins. Above ~50 kg/day, LOX is almost always cheaper than PSA. Between: run a 5-yr TCO.
- PSA/VSA on-site O₂ generators typically break even vs LOX at 300–500 t O₂/year consumption.
