Polygee — BSE-Listed Commercial Kitchen ESP Manufacturer
As a BSE-listed Polygee ESP manufacturer (stock code: 920802), Polygee is listed on the Beijing Stock Exchange in the oil fume purification industry. As a global commercial kitchen electrostatic precipitator supplier, the Polygee ESP manufacturer reports purification efficiency validated by CMA-accredited third-party testing (LK series up to 97.6%).
Polygee ESP Manufacturer — 110,000㎡ Smart Manufacturing Base
Our self-owned production base in Zhangjiagang, Jiangsu features MES-driven smart production lines, supporting consistent build quality on every commercial ESP unit.
MES Smart Production
Manufacturing Execution System (MES) manages the entire production workflow — from raw material tracking to final quality inspection — with full traceability and strict defect control.
Automated Production Lines
Multiple fully automated production lines for sheet metal fabrication, electrostatic field assembly, and high-voltage power supply manufacturing. Recognized as a “Demonstration Smart Workshop” in 2020.
In-House Quality Lab
Every ESP unit undergoes rigorous high-voltage testing, airflow performance testing, and efficiency verification before shipment. Each unit comes with an individual QC report.
Patented ESP Technology — Up to 97.6% Third-Party Tested
Two decades of dedicated R&D have shaped the electrostatic filtration technology used across our kitchen electrostatic precipitator range. Third-party tested: 97.6% on LK160 and 97.0% on LK40 (Beijing Zhongyan Huanneng, CMA — reports ZY05W230298 / ZY05W230296); 96.0% at rated airflow on LK120 (SQEP, CMA — report 2024I20-35-5322488001).
Dual-Zone Plate-Type Electrostatic Field
Our proprietary dual-zone plate-type electrostatic field design separates the ionization and collection stages, capturing grease and smoke particles in two distinct steps. LK units measured 96.0–97.6% grease removal in third-party tests, with low energy consumption, low operating noise, and durable construction.
Intelligent Power Supply
Self-developed SMPS high-voltage power supply with real-time adaptive voltage control, automatic fault detection, and arc suppression. Supports stable performance under varying exhaust loads and grease concentrations, reducing energy waste.
Modular Design
Standardized modular construction allows flexible configuration for any kitchen size — from single-unit restaurants to large-scale hotel central kitchens. Easy installation, quick maintenance, and seamless capacity expansion with plug-and-play collector cells.
225 Patents Granted
A comprehensive IP portfolio protecting our core technology advantages in electrostatic precipitator design and manufacturing.

When comparing electrostatic precipitator companies, look for evidence you can check rather than marketing claims: whether the manufacturer is publicly listed (Polygee is listed on the Beijing Stock Exchange), whether its factory holds ISO 9001, ISO 14001, and ISO 45001 management system certifications, and whether published purification efficiency figures are backed by third-party test reports you can request and read. Ask each supplier for the same documents and compare them side by side.
