水產養殖高效能增氧系統 RAS | YUTANK

特徵

• 高氧轉移效率
  該系統整合了細氣泡擴散器和低頭氧錐，能夠在高密度水箱中快速恢復溶解氧。在海外孵化場的測試中，即使在生物量負荷達到高峰的情況下，水箱深度1.2至1.5公尺時，氧飽和度也能持續維持在90%以上。

• 模組化，適用於多罐部署
  每個單元均獨立連接管道並配備 PLC，適用於分階段安裝或中央歧管設定。這對於逐步擴大規模或運行混合物種程式的 RAS 操作員尤其實用。

• 耐腐蝕、海洋級結構
  所有濕潤部件（管道、腔室和夾具）均採用玻璃鋼、高密度聚乙烯或316不銹鋼材質，取決於鹽度。多家營運鹹水系統的國際客戶報告稱，其結構在18-24個月後仍未出現任何老化。

• 低能耗
  該系統達到目標溶氧量 (DO) 所需的能耗不到文丘里系統通常消耗的 kWh/t·O₂ 的 25%。這直接轉化為全天候曝氣設施的成本節省——智利一家養殖場的每池單元每月營運成本下降了 420 美元。

• 內建安全冗餘
  整合式旁通閥和警報連動流量感知器可防止過壓或氧氣回流。這是偏遠地區客戶提出的常見要求，因為這些地區的人員輪調可能會延遲事件回應。

• 與 O₃ 和 UV 整合環路相容
  設計旨在與蛋白質分離器、臭氧接觸器或紫外線消毒器在同一迴路中無縫運行，從而降低管道複雜性並減少潛在死角。在歐洲 RAS 設施中進行的系統測試證實，所有連接點的流速均達到平衡。

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.
