Shrimp Farm Aeration Upgrade: Replacing 132 kW Roots Blowers with 95 kW Maglev Turbo Blower
In modern shrimp farming, aeration is not just a supporting utility — it is a core production system. Dissolved oxygen levels directly affect shrimp survival rate, growth speed, feed conversion ratio, and overall pond stability. Any fluctuation or failure in aeration can quickly lead to biological stress and economic loss.
This project involved a large-scale shrimp farm that had been operating with traditional Roots blowers for years. While the system was familiar and proven, rising electricity costs, increasing maintenance effort, and concerns about long-term operational risk pushed the farm to look for a more stable and efficient aeration solution.
Existing System Challenges
Before the upgrade, the shrimp farm relied on 132 kW Roots blowers to supply air for pond oxygenation. Over time, several challenges became increasingly apparent:
- High energy consumption, especially during long continuous operation
- Frequent maintenance, including belts, lubrication, and mechanical wear
- Noise and vibration, affecting on-site working conditions
- Operational risk, as oil-based mechanical components always pose contamination concerns in aquaculture environments
While the Roots blowers could meet airflow requirements, the overall system efficiency and reliability no longer aligned with the farm’s long-term operational goals.
The Upgrade Solution: RAETTS 95 kW Maglev Turbo Blower
After technical evaluation, the farm decided to replace the existing Roots blower system with a RAETTS 95 kW magnetic levitation (maglev) turbo blower designed specifically for continuous-duty aeration applications.
Unlike conventional blowers, the RAETTS maglev turbo blower uses oil-free, contact-free magnetic bearings, eliminating mechanical friction and lubrication requirements. This design is particularly suitable for aquaculture, where cleanliness, reliability, and stable airflow are critical.
Key Results and Performance Improvements
1. Energy Efficiency Improvement
By replacing the 132 kW Roots blower with a 95 kW maglev turbo blower, the shrimp farm achieved approximately 30% energy savings while maintaining the required oxygen supply.
This reduction in power consumption translates directly into lower operating expenditure (OPEX), which is especially important for aquaculture facilities running aeration systems 24 hours a day.
2. Stable Oxygen Supply
Beyond energy savings, the most noticeable improvement was operational stability. The maglev turbo blower provides precise airflow control and fast response to load changes, resulting in a more consistent oxygen supply across the ponds.
For shrimp farming operations, this stability helps reduce stress on the stock and supports healthier growth conditions.
3. Oil-Free and Low Maintenance Operation
The RAETTS maglev turbo blower operates without oil, gears, or belts. This eliminates the risk of oil contamination and significantly reduces routine maintenance work.
Maintenance is largely limited to periodic filter replacement, allowing farm operators to focus more on production management rather than equipment upkeep.
4. Improved Working Environment
The upgrade also resulted in lower noise and vibration levels compared to the previous Roots blower system. This improvement enhanced on-site working conditions and reduced the need for additional soundproofing measures.
Why Maglev Technology Fits Aquaculture Applications
Aquaculture aeration systems require equipment that can run continuously with minimal intervention. Maglev turbo blowers are increasingly adopted in shrimp farming and fish farming due to their:
- High efficiency at partial and variable loads
- Oil-free and contamination-free operation
- Low vibration and quiet performance
- Long service life with minimal mechanical wear
For farms facing rising energy prices and stricter environmental standards, maglev technology offers a future-proof aeration solution.
Conclusion: From Utility Equipment to Production Asset
This shrimp farm aeration upgrade demonstrates that aeration systems should not be viewed merely as a utility cost. When properly designed and selected, they become a strategic production asset that improves stability, reduces risk, and lowers long-term operating costs.
By replacing traditional Roots blowers with a RAETTS maglev turbo blower, the farm achieved meaningful energy savings, improved oxygen stability, and a more reliable, aquaculture-friendly aeration system.
For shrimp farms and aquaculture operators seeking to optimize oxygenation while controlling energy and maintenance costs, maglev turbo blowers represent a proven and sustainable upgrade path.
