Applicazioni tipiche
- High-density RAS grow-out
- Emergency oxygenation loops
- Marine hatcheries with tight DO targets
Dimensioni progetto
- Per unit: $10K–$150K
- Commercial RAS system: $100K–$3M
Criteri di selezione
- Transfer efficiency (%) at operating conditions
- Head loss and pumping cost
- Turndown ratio
- Materials for salinity and CIP
Domande da porre
- What transfer efficiency at my target DO and flow?
- What is the head loss curve?
- How do you handle CIP?
Errori comuni di procurement
- Choosing cones sized for average, not peak biomass
- Ignoring turndown at low load
Raccomandazioni RFQ
- Tender against transfer efficiency spec, not brand
