On-site Oxygen Generators For Aquaculture
Description
Technical Parameters
Boost Health & Growth:
Higher dissolved oxygen supports strong metabolism, faster growth, and less stress-lowering mortality, improving feed conversion, and yielding quality aquatic products.
Stable 24/7 Supply:
On-site generation cuts external delivery reliance, avoiding disruptions from delayed or depleted cylinders.
Cost-Saving & Fast ROI:
Eliminate cylinder rental, delivery, and ADR fees; achieve ROI in months, reducing long-term costs for all farm scales.
Improve Water Quality:
Sustained oxygen breaks down waste, regulates ammonia/CO₂, and serves as ozone generator feed gas for enhanced purification.
Eco-Safe:
Reduce transport emissions and eliminate hazardous high-pressure cylinder handling, minimizing risks and environmental impact.

FAQ
1.What benefits can the on-site oxygen generator bring to fish growth and health?
It maintains higher dissolved oxygen levels to boost fish metabolism, shorten production cycles, and reduce stress. This lowers mortality rates, improves feed conversion efficiency, and ultimately yields healthier, high-quality aquatic products.
2.How does the on-site generator ensure uninterrupted oxygen supply for aquaculture?
On-site generation eliminates reliance on external oxygen deliveries. It provides 24/7 stable oxygen, avoiding disruptions caused by delayed deliveries or depleted cylinders that affect continuous aquaculture operations.
3. What cost savings can be achieved, and how long does it take to get ROI?
It cuts expenses for cylinder rentals, deliveries, and ADR fees. The system often achieves return on investment within months, reducing long-term operational costs for both small farms and large-scale facilities.
4.Is the generator suitable for different types of aquaculture operations?
Yes, it's highly scalable and flexible. It adapts to land-based RAS facilities, sea cages, hatcheries, offshore farms, and even specialized habitats like zoo aquatic enclosures, with configurable setups for diverse needs.
5. What makes the product eco-friendly and safe for use?
It reduces transport-related emissions by replacing delivered oxygen cylinders. It also eliminates the need to handle hazardous high-pressure cylinders, minimizing safety risks and reducing environmental footprint.
