For overseas aquaculture farmers, unstable oxygen levels in fish tanks can lead to massive fish deaths—costing thousands of dollars yearly. As a professional China inverter manufacturer, AUSENIST developed the YS620 Variable Frequency Drive (also called an inverter) to solve this pain point, specifically for oxygen pumps in fish farms.

This frequency converter connects to oxygen sensors in water, automatically adjusting pump speed based on real-time oxygen levels. When levels are high, it slows the pump to save energy; when levels drop, it speeds up to boost aeration. A fish farm in Vietnam tested 10 YS620s and saw a 15% increase in fish survival rates—compared to their old fixed-speed pumps, which often over-aerated (wasting 22% electricity) or under-aerated (causing mortality).

“The YS620 doesn’t just keep our fish alive; it cuts our electricity bills by $300/month,” said the Vietnamese farm owner. AUSENIST also optimized the YS620 for aquaculture’s harsh conditions: its anti-corrosion coating resists saltwater damage, and the IP54 rating keeps out moisture. As a China frequency converter supplier, AUSENIST even provided Vietnamese-language manuals and 24/7 local-language support, so the farm’s staff could operate it easily.

Overseas wineries know: grape quality depends on precise irrigation—too much water dilutes flavor, too little stunts growth. AUSENIST’s YS620 pump inverter (a Variable Frequency Drive) is designed to solve this, making it a top choice for vineyards in France, Italy, and Chile.

This AC Drive syncs with soil moisture sensors and grape variety data (e.g., Cabernet Sauvignon needs 20% less water than Chardonnay) to adjust watering automatically. A French winery in Bordeaux reported a 5% increase in grape sugar content (critical for wine flavor) and 28% less water use after installing YS620s. “We used to water all vines the same way—now the YS620 tailors it to each row,” said the winemaker.

As a China inverter manufacturer, AUSENIST ensured the YS620 meets EU standards: it’s CE-certified, RoHS-compliant, and has the EU Ecolabel for energy efficiency—critical for customs clearance in Europe. It also runs quietly (under 58dB), so it doesn’t disturb vineyard tours. “Our customers never notice the pumps now,” added the winemaker. AUSENIST even provided a 2-year warranty and fast spare parts delivery to Europe, so downtime is minimized.

Overseas greenhouse growers need irrigation that matches plant growth stages—seedlings need light watering, mature plants need more. AUSENIST’s YS620 pump VFD (a frequency converter) makes this easy, connecting to greenhouse climate controllers to adjust water flow and frequency.

A Dutch tomato greenhouse tested 8 YS620s and saw a 12% increase in yield: the Variable Speed Drive waters seedlings for 2 minutes/hour and mature plants for 5 minutes/hour, avoiding overwatering (which causes root rot) and underwatering (which stunts growth). It also saves 25% energy vs. fixed-speed pumps, critical for Dutch growers facing high electricity costs.

As a China AC Drive manufacturer, AUSENIST optimized the YS620 for greenhouses’ humid environments (IP54 rating) and provided integration support with Dutch climate control systems (e.g., Priva). “The YS620 works seamlessly with our existing setup—no extra wiring needed,” said the greenhouse manager. It also has a data logging function, so growers can track watering patterns and optimize yields further. AUSENIST’s 24/7 English support ensures any issues are fixed fast, even during peak growing seasons.
