Core Function Positioning
This product is designed for high-density cod farming scenarios, focusing on improving the dissolved oxygen concentration in water bodies and optimizing the growth environment of fish, especially for the low temperature and high oxygen consumption characteristics of cod farming in cold waters.
Differentiation Highlight Design
Full-cycle worry-free service: one-year warranty + free on-site installation
365-day ultra-long warranty: covering core components (such as oxygen production membrane group, control system), providing free fault repair service, and reducing the maintenance cost of farm equipment.
Professional technical team on-site installation: customize oxygen pipeline solutions according to the layout of the breeding pond to ensure seamless connection between the equipment and the breeding environment, and avoid efficiency loss caused by improper installation.
Low Temperature Adaptive System
In view of the cold water environment (usually 4-10℃) where cod survive, cold-resistant oxygen-generating membrane materials are used to ensure that the oxygen output rate is stable at ≥90% at low temperatures.
Layered Dissolved Oxygen Control
The vertical dissolved oxygen gradient of the water body is adjusted through a multi-stage diffuser to match the layered habitat habits of cod and reduce oxygen waste.
IoT remote monitoring
Supports real-time viewing of dissolved oxygen content, equipment energy consumption and other data on mobile phones/PCs, and automatically alarms and pushes solutions for abnormal conditions.
Energy-saving mode linkage
Automatically switches operating power according to feeding time and water temperature changes, and saves 15%-20% of energy in total.
FAQ
Q: How to calculate the oxygen generator capacity required for cod farming?
A: Cod is a high oxygen consumption cold water fish. The breeding density and water temperature fluctuations directly affect the oxygen demand.Key parameters: fish density (kg/m³), water temperature (low temperature requires an additional 5-10% oxygen supply), water circulation efficiency.
Calculation formula:
Oxygen demand (kg O₂/h) = fish weight (kg) × oxygen consumption rate (cod is about 0.2-0.3kg O₂/ton fish/hour) × safety factor (1.5-2)
Q: In a seawater aquaculture environment, how does the oxygen generator resist salt spray corrosion?
A: Technical points:
1. Material selection: 316L stainless steel body, titanium alloy diffuser.
2. Protection design: IP68 waterproof grade + anti-salt spray coating.
3. Maintenance cycle: It is recommended to check the seal every 3 months.
Q: Will the dissolution efficiency of the oxygen generator decrease in a low temperature (<5℃) environment?
A:1. Adopt nano bubble technology (bubble diameter <30nm), the dissolution rate at low temperature is increased by 40%.
2. Equipped with water temperature sensing system, automatically adjust the air pump pressure to compensate for dissolution efficiency.
User real data: measured in Nordic cod farms, 6.5mg/L dissolved oxygen is still maintained at -2℃.
Q: How to balance oxygen supply and energy consumption cost?
A:1. Choose variable frequency PSA oxygen generator, which saves 30% energy compared with traditional models.
2. With intelligent dissolved oxygen controller, dynamically adjust oxygen supply according to real-time monitoring data.
3. It is recommended to configure oxygen storage tanks in peak and valley electricity price areas (buffer low load demand at night).
Q: How to ensure the survival of cod in case of sudden power outage?
A: We are equipped with the following facilities:
1. Dual power supply redundant system: automatic switching of mains power + diesel generator (switching time <15 seconds).
2. Spare liquid oxygen tank: at least 12 hours of oxygen reserve (calculated according to maximum breeding density).
3. Low power consumption alarm device: automatically send SMS/APP notification when power is off.
