INVT's Medium-voltage VFD solution for SO₂ fans is tailored to the operating conditions of SO₂ fans in copper smelting. It features anti-corrosion, anti-shock performance and precise speed regulation, ensuring stable operation, environmental compliance, cost reduction and efficiency improvement.
Highly corrosive operating conditions: SO₂ flue gas contains acid mist and sulfide dust, which corrode components and circuit boards, resulting in a high failure rate.
Risk of environmental penalties: High equipment stability is required; shutdowns caused by failures lead to excessive SO₂ emission concentrations and trigger alarms from online environmental monitoring systems.
Lack of fault location and early warning: Incomplete fault data collection makes it difficult to predict hidden failures (e.g., power unit aging), and troubleshooting after sudden shutdowns is time-consuming.
Poor adaptability to harmonics and power grid: Grid voltage fluctuations and harmonic interference cause false tripping and unwanted protection actions of VFDs, leading to unplanned downtime and risks to production continuity.
INVT GD5000 series medium-voltage VFDs feature high reliability, precise control, easy maintenance and full compliance as their core strengths.They adapt to the harsh medium-voltage working conditions of SO₂ fans in copper smelting, solve pain points such as corrosion, load fluctuations and environmental non-compliance, and ensure continuous equipment operation, environmental compliance, cost reduction and efficiency improvement.
View Larger ImageAnti-corrosion & Weatherproof Protection: Power units with enhanced three-proof treatment plus high-protection enclosure, resisting acid mist and dust corrosion to ensure stable insulation.
High-Overload & Precise Speed Regulation: 150% heavy overload design combined with high-precision algorithms, resisting load impact and meeting environmental air volume requirements.
Grid Self-Adaptation: LVRT (Low Voltage Ride-Through) for uninterrupted operation during momentary power dips, and automatic power unit bypass technology.
IoT-Based O&M: Integrated remote IoT system enabling remote monitoring, active fault alarm, remote diagnosis and predictive maintenance.
The "automatic bypass for faulty units" technology eliminates unplanned downtime caused by VFD failures and improves production efficiency.
Operation continues despite grid voltage fluctuations; reduces unexpected shutdowns and ensures stable production.
Multi-level topology combined with dedicated fan energy-saving algorithms significantly reduces power consumption per ton of acid, greatly cutting long-term electricity costs.
Real-time remote system monitoring enables rapid fault location and diagnosis, avoiding losses from production halts.
