Medium & High Voltage VFD Solutions for Petrochemical Industry
Sunsin three-level medium & high voltage VFD features explosion-proof, anti-corrosion and low harmonic design, ideal for chemical pumps, compressors and reactor equipment in petrochemical plants.
- Flammable & explosive mixed gas in chemical workshops, strict safety protection standards for all electrical equipment
- Corrosive chemical vapor, acid mist and dust erode circuit boards and metal parts, accelerating equipment aging
- Long-term continuous operation of chemical pumps and compressors, huge power loss under constant frequency operation
- Small factory self-owned power grid, harmonic distortion easily triggers instrument misoperation and power grid resonance
- Sudden load fluctuation during chemical reaction production, requiring strong overload and anti-impact performance
- High ambient temperature inside chemical plant buildings, demanding reliable heat dissipation structure for drives
Four Core Product Advantages
Safety & corrosion resistant customized VFD for petrochemical harsh environment
Explosion-proof & Intrinsically Safe Cabinet Design
Optional explosion-proof cabinet structure compliant with chemical industry safety standards. Isolated air channel design blocks flammable gas from contacting internal power modules, eliminating hidden fire risks for refinery and chemical workshop installation.
Anti-corrosion & Three-proof Circuit Protection
All circuit boards pass special damp-proof, mildew-proof and anti-corrosion coating treatment. Sealed IP54 cabinet prevents acid mist, chemical dust and corrosive gas from entering the unit, greatly extending service life in chemical plant environments.
Ultra-low Harmonic Three-level Topology
NPC three-level output waveform is close to standard sine wave, effectively reduce total harmonic distortion. No extra filter equipment needed, avoids interference with precision chemical control instruments and factory power distribution system.
Heavy-duty Stable Energy-saving Control
Support 150% overload for 60s, perfect for variable loads of chemical compressors and reaction pumps. Stepless speed regulation matches real production flow, achieving 18%-35% long-term power saving rate for petrochemical enterprises.
