水产养殖高效增氧系统 RAS | YUTANK

特征

• 高氧转移效率
  该系统集成了细气泡扩散器和低头氧锥，能够在高密度水箱中快速恢复溶解氧。在海外孵化场的测试中，即使在生物量负荷达到峰值的情况下，水箱深度1.2至1.5米时，氧饱和度也能持续保持在90%以上。

• 模块化，适用于多罐部署
  每个单元均独立连接管道并配备 PLC，适用于分阶段安装或中央歧管设置。这对于逐步扩大规模或运行混合物种程序的 RAS 操作员尤其实用。

• 耐腐蚀、海洋级结构
  所有湿润部件（管道、腔室和夹具）均采用玻璃钢、高密度聚乙烯或316不锈钢材质，具体取决于盐度。多家运营咸水系统的国际客户报告称，其结构在18-24个月后仍未出现任何老化。

• 低能耗
  该系统达到目标溶解氧 (DO) 所需的能耗不到文丘里系统通常消耗的 kWh/t·O₂ 的 25%。这直接转化为全天候曝气设施的成本节省——智利一家养殖场的每池单元每月运营成本下降了 420 美元。

• 内置安全冗余
  集成旁通阀和报警联动流量传感器可防止过压或氧气回流。这是偏远地区客户提出的常见要求，因为这些地区的人员轮换可能会延迟事件响应。

• 与 O₃ 和 UV 集成环路兼容
  设计旨在与蛋白质分离器、臭氧接触器或紫外线消毒器在同一回路中无缝运行，从而降低管道复杂性并减少潜在死角。在欧洲 RAS 设施中进行的系统测试证实，所有连接点的流速均达到平衡。

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.
