Oxygen Cones & Contactors — Dissolution Systems Buyer's Guide
Oxygen cones (Speece cones) and low-head oxygenators dissolve pure oxygen into water at 85–95% transfer efficiency. In intensive RAS they replace inefficient venturis and aeration for peak biomass.

Typical applications
- High-density RAS grow-out
- Emergency oxygenation loops
- Marine hatcheries with tight DO targets
Project sizes
- Per unit: $10K–$150K
- Commercial RAS system: $100K–$3M
Selection criteria
- Transfer efficiency (%) at operating conditions
- Head loss and pumping cost
- Turndown ratio
- Materials for salinity and CIP
Questions buyers should ask
- What transfer efficiency at my target DO and flow?
- What is the head loss curve?
- How do you handle CIP?
Common procurement mistakes
- Choosing cones sized for average, not peak biomass
- Ignoring turndown at low load
RFQ recommendations
- Tender against transfer efficiency spec, not brand
