High-Efficiency Oxygenation Systems for Aquaculture RAS

Features

• High Oxygen Transfer Efficiency
  The system integrates fine-bubble diffusers and low-head oxygen cones, enabling rapid DO recovery in high-density tanks. In tests across overseas hatcheries, oxygen saturation consistently remained above 90% at 1.2–1.5 m tank depth, even under peak biomass load.

• Modular for Multi-Tank Deployment
  Each unit is independently plumbed and PLC-ready, making it suitable for staged installations or central manifold setups. This is especially practical for RAS operators scaling gradually or running mixed-species programs.

• Corrosion-Resistant, Marine-Grade Construction
  All wetted components—pipes, chambers, and clamps—use FRP, HDPE, or 316 stainless steel depending on salinity level. Several international clients operating brackish water systems have reported zero structural degradation after 18–24 months.

• Low Energy Demand
  System achieves target DO with less than 25% of the kWh/t·O₂ typically consumed by venturi systems. This directly translates to cost savings in facilities with 24/7 aeration demands—one farm in Chile recorded a $420/month drop in operating cost per tank block.

• Built-in Safety Redundancy
  Integrated bypass valve and alarm-linked flow sensor prevent over-pressurization or oxygen backflow. This is a common request from clients in remote facilities where staff rotation may delay incident response.

• Compatible with O₃ and UV-Integrated Loops
  Designed to function seamlessly with protein skimmers, ozone contactors, or UV sterilizers in the same loop—reducing plumbing complexity and potential dead spots. System tests in European RAS facilities confirmed balanced flow velocity at all connection points.

Packing:
All oxygenation units are securely mounted on fumigated plywood pallets with shock-absorbing fasteners. Key interfaces are capped and bag-sealed to prevent moisture or dust entry during transit. Each shipment includes a full set of connection fittings, operation manual, and serialized QC labels for traceability.

Shipping:
We ship globally from our Guangdong-based export warehouse. Standard lead time for regular models (YT-OXY300/500/800) is 10–12 working days after deposit confirmation. For OEM variants or container-mixed orders, lead time may extend by 5–7 working days. Express air freight is available for hatchery emergencies, subject to dimensional limits.

Delivery Options:
EXW, FOB Shenzhen, and CIF main ports supported. Long-term partners often consolidate with other aquaculture units (e.g., biofilters or skimmers) to optimize container fill rate. We assist with customs documentation, HS code declaration (8419601900), and CE form-A for eligible regions.

After-Sales Support:
Remote commissioning support and initial setup walkthrough are provided via video call or localized agent (where available). For first-time international installations, we provide oxygenation performance charts based on water flow and DO demand curves. Spare membrane kits and diffusers can be shipped in advance with main cargo or separately on reorder cycle.

FAQ – High-Efficiency Oxygenation Systems for RAS & Hatcheries

Q1: Can this oxygenation system handle high stocking density in recirculating aquaculture setups?
Yes. Our models such as YT-OXY800 are engineered for intensive RAS operations, capable of maintaining dissolved oxygen (DO) above 6.5 mg/L even in systems with over 50 kg/m³ biomass density. Performance remains stable under continuous flow and varying load.

Q2: What’s the difference between your oxygen diffusers and common venturi injectors?
Unlike venturi systems that rely on pressure drop, our fine-bubble ceramic diffusers offer consistent microbubble output with minimal backpressure. This increases oxygen transfer efficiency (OTE) up to 85%, especially in vertical contact columns or sump-integrated loops.

Q3: Are these systems compatible with ozone or UV sterilization in the same loop?
Yes, as long as correct sequencing is followed. We usually recommend placing oxygenation after UV and before biofiltration. If ozone is used, check for oxidation-resistant seals (EPDM or Viton) on all relevant components.

Q4: What kind of maintenance is required, and how often?
Routine maintenance is minimal. Ceramic diffusers only require acid soaking every 3–6 months depending on water quality. Oxygen generator units (if included) follow a 1000–2000 hr service interval for filters and membrane replacement.

Q5: Can you provide sizing support for my hatchery layout?
Absolutely. Send us your flow rate, DO targets, tank volume, and species stocking density. Our team will run the oxygen demand projection and suggest suitable models, including diffuser spacing and pipe routing if needed.

Q6: How is the system shipped and what’s included?
Each unit comes preassembled (or modular with labeled quick-connect points) and includes diffusers, oxygen inlet connectors, mounting clamps, and instruction manual. We also include startup guidelines and performance calibration chart for reference.
