The Challenge: Why Commercial Kitchens Need Better Exhaust Solutions
In any bustling city, commercial kitchen exhaust is a growing problem. Dense cooking smoke drifts toward residential buildings. Grease accumulates inside ductwork, creating serious fire hazards. Traditional metal mesh filters capture only 40%–60% of grease particles — the rest becomes a ticking time bomb.
As environmental regulations tighten worldwide, a high-efficiency exhaust purification system is no longer optional — it is the lifeline of every commercial kitchen.
Electrostatic precipitation (ESP) technology is the answer. By using high-voltage electrostatic fields to capture grease at the molecular level, ESP systems achieve 90%–99% removal efficiency without disposable filters — far beyond what any passive mesh or baffle filter can deliver.
Our Story: 20 Years Dedicated to One Mission
Founded in 2004 in Zhangjiagang, Jiangsu Province, Polygee has spent two decades focused on a single mission: manufacturing the world’s most reliable commercial kitchen electrostatic precipitators.
- 2004 — Company founded in Zhangjiagang, dedicated to ESP R&D and manufacturing
- Corporate Restructuring — Transformed into a joint-stock company with modern governance
- NEEQ Listing (920802) — Secured capital for technology expansion and global market development
- 2010s — Achieved CE, RoHS, ISO 9001, ISO 14001, and ISO 45001 certifications
- 2020 — Recognized as a "Demonstration Smart Workshop"; launched IoT-enabled DESP series
- 2023 — IPO on Beijing Stock Exchange (BSE: 920802) — China’s first A-share listed fume purification company; UL certified for North America
Today, Polygee holds 179 patents, operates a 100,000+ sqm smart factory with 300+ employees, and exports to 50+ countries across five continents.
Our Core Technology: Plate-Type Electrostatic Field
At the heart of every Polygee ESP is our proprietary dual-zone plate-type electrostatic field — the technology that sets us apart. Unlike honeycomb designs, our plate-type architecture separates ionization and collection into two independent, optimized stages.
Stage 1 — Ionization: High-voltage wires (12–13kV) charge every grease and smoke particle, including sub-micron oil mist invisible to the naked eye.
Stage 2 — Collection: Flat aluminum plates with alternating polarity attract and deposit charged particles. Grease drains to collection trays automatically.
Why Plate-Type Outperforms Honeycomb
- 90%–99% efficiency — Independent ionization and collection with zero interference
- Easy cleaning — Flat plates with no dead zones; soak in degreaser or run through a dishwasher
- 10+ year lifespan — Washable and reusable collector cells with zero consumable costs
- Lower maintenance — Quarterly cleaning vs. monthly for honeycomb designs
Intelligent Power Supply
- Adaptive voltage — Auto-adjusts output based on real-time exhaust load
- Arc suppression — Automatic fault detection, instant cut-off and self-recovery
- 30% energy savings compared to traditional line-frequency power supplies
These core technologies are protected by 179 authorized patents (39 invention + 81 utility model + 59 design).
