INVT provides a ventilation system based on intelligent variable frequency control, enabling precise air volume regulation. Its value lies in energy saving, high efficiency, improved production safety, and reduced operation and maintenance costs.
High energy consumption risk: Huge fan energy consumption and high electricity costs.
Potential safety hazards: Unstable air volume leads to insufficient oxygen supply and risks of underground accidents.
Operation and maintenance difficulties: Frequent equipment failures, high maintenance costs and long downtime.
Low reliability: Aging equipment or inaccurate regulation results in continuous production interruptions.
WithMedium-voltage frequency converters as the core equipment and combined with the Internet plus monitoring platform architecture, intelligent closed-loop control of air volume is realized. The control logic optimizes fan start-stop and speed regulation to precisely match mine requirements. Supplemented by remote diagnosis and predictive maintenance services, efficient and stable operation is ensured. The strategy emphasizes intelligence, energy efficiency and proactive operation and maintenance.
