INVT provides an intelligent variable frequency control system for auxiliary fans. By replacing damper throttling with variable frequency speed regulation, it realizes variable frequency soft start and one-operation one-standby mode, achieving safe, efficient and unmanned operation.
High energy consumption: Damper throttling causes redundant power consumption.
Safety risks: Surge impacts equipment and slow emergency startup threatens underground ventilation safety.
High operation and maintenance costs: Requires manual on-duty monitoring plus frequent maintenance (bearing/blade wear).
Grid penalties: Low power factor (often < 0.8) triggers penalties from the power authority.
It integrates the fan drive control system and data acquisition system. Based on the collected data such as gas concentration, temperature, wind speed, carbon monoxide content and dust density, it can realize intelligent ventilation and intelligent gas drainage.Through the supporting IoT module, remote data monitoring is available. It is compatible with the standard communication interfaces of smart mines, facilitating access to the underground ring network and uploading data to the dispatch and command center.
View Larger Image- Redundancy: Equipped with two independent speed control systems in one unit, supporting variable-frequency soft start and one-operation one-standby mode.
- Safety: Eliminates surges and enables second-level emergency startup, directly addressing core pain points in coal mine ventilation.
- Cost Reduction: Labor savings combined with elimination of reactive power compensation devices deliver synergistic benefits.
- Long-Term Benefits: Extended equipment lifespan significantly reduces the full-life-cycle TCO (Total Cost of Ownership).
Reduces annual electricity cost and equipment wear.
With ±15% wide voltage adaptability, ensures stable and reliable operation, improves voltage sag recovery efficiency, and guarantees production continuity.
