TAIZHOU CHIYE ELECTROMECHANICAL CO., LTD.
Three Decades of Air Dynamics Engineering Excellence, Manufacturing Robust Kitchen Ventilation & Industrial Exhaust Infrastructure.
Founded in 1995 (formerly known as Wenling Zeguo Wanfang Mechanical and Electrical Parts Factory), TAIZHOU CHIYE ELECTROMECHANICAL CO., LTD. has grown into a premier industrial backbone enterprise specializing in high-performance ventilation technology, industrial blowers, air conditioning supply units, and commercial kitchen-dedicated fans. Based in Taizhou, Zhejiang—China's electromechanical manufacturing hub—Chiye Enterprise operates state-of-the-art standard factory buildings, extensive modern logistics warehouses, an advanced wind turbine aerodynamic research center, and a dedicated precision wind turbine processing division.
Modern commercial catering, hospitality kitchens, and industrial processing operations demand ventilation hardware capable of operating reliably under severe thermal, grease-laden, and chemically aggressive conditions. A kitchen ventilation fan service provider and manufacturer must deliver more than just basic airflow; it requires systemic fluid dynamics engineering, high structural rigidity, low-noise acoustic management, and long-term energy efficiency. Chiye has spent nearly three decades refining OEM/ODM solutions supporting major domestic and international ventilation brand manufacturers, environmental dust extraction system integrators, boiler equipment manufacturers, and commercial building contractors.

Kitchen Exhaust Dynamics & Technical Fan Architecture
Resolving key technical challenges: grease accumulation, high static pressure requirements, continuous duty cycle thermal management, and noise compliance.
1. Multi-Wing & Centrifugal Airflow Mechanics (11-62, DFA, SRE, & BCF Series)
Commercial kitchen grease exhaust ducts usually feature extended horizontal runs, electrostatic precipitators (ESP), carbon filters, and multiple 90-degree elbows. Traditional axial fans fail to overcome the high static pressure drop of these systems. Chiye’s centrifugal series—such as the 11-62 ODM Kitchen Fan, DFA High-Efficiency Centrifugal Fan, and SRE Multi-Wing Low Noise Fan—employ forward-curved and backward-inclined multi-wing steel impellers.
- Oil Fume Centrifugal Separation (CY-16 Series): Specifically engineered for commercial fryers and high-smoke Asian cooking setups. The centrifugal force generated by high-speed rotation throws airborne oil droplets onto the casing walls, where they drain into internal collection channels, protecting the downstream motor from oil degradation.
- Low Noise Acoustic Volute Design: Scroll casings designed via computational fluid dynamics (CFD) minimize internal air turbulence and vortex shedding, significantly reducing dBA noise output while maintaining maximum volumetric flow rates (CFM).
2. Fire Protection & High-Temperature Smoke Evacuation (HTF Series)
In modern commercial buildings, kitchen exhaust systems frequently double as emergency smoke extraction systems. Chiye’s HTF Series Fire Protection High-Temperature Smoke Dedicated Fan is engineered to withstand extreme elevated thermal conditions. Built with specialized heat-resistant alloys, Class H insulated copper-wound motors, and direct/belt-drive isolation chambers, these fans are rated to operate continuously at 280°C to 300°C for over 0.5 to 2 hours during building fire events, maintaining structural integrity to allow occupant evacuation.
3. Heavy Corrosion Resistance: 304 Stainless Steel Construction (9-19A Series)
For high-moisture, chemical, or saltwater-exposed kitchen environments (such as marine catering or chemical washing kitchens), Chiye offers the Custom 9-19A Stainless Steel (304 Material) High-Pressure Centrifugal Fan. Featuring precision-welded 304 grade austenitic stainless steel casings and impellers, these units offer absolute immunity against organic fatty acid oxidation, alkaline detergents, and environmental rust.

Frequently Asked Questions (FAQ)
Expert engineering answers regarding kitchen fan selection, maintenance, aerodynamic sizing, and compliance standards.
Q1: How do centrifugal kitchen fans compare to axial fans for grease fume exhaust?
Centrifugal fans (such as the 11-62 and DFA series) generate significantly higher static pressure compared to axial fans. Grease-laden exhaust air from commercial kitchens must pass through hood filters, duct bends, grease traps, and filtration units (ESP), creating high static resistance. Centrifugal blowers maintain stable volumetric airflow against this resistance, preventing grease build-up and backdrafts.
Q2: What makes the HTF Series suitable for fire smoke extraction?
The HTF Series is designed with high-temperature resistance features, including specialized metal alloys, dual-speed motors, thermal barrier chambers, and Class H insulation. It performs standard continuous ventilation during daily operations and can automatically switch to emergency high-speed smoke exhaust during a fire, operating at 280°C–300°C for up to two hours under international fire code standards.
Q3: Why is dynamic balancing crucial for commercial kitchen fans?
Commercial kitchen fans frequently accumulate grease onto impeller blades over time. If an impeller is not precisely balanced from the factory (to ISO 1940 G2.5 standards via digital balancing machines), small weight imbalances can lead to motor vibration, excessive noise, premature bearing failure, and casing stress. Chiye uses 6 computer digital dynamic balancing systems to verify every fan wheel prior to assembly.
Q4: When should a 304 Stainless Steel centrifugal fan (like the 9-19A) be specified?
Stainless steel 304 fan construction is essential in highly corrosive environments, such as seafood processing kitchens, chemical treatment plants, salt-spray marine environments, or facilities using aggressive alkaline cleaning agents. Stainless steel prevents rust, corrosion, and organic fatty acid degradation, drastically extending the service life of the fan.
Q5: What customized OEM services can Chiye provide for international ventilation brands?
Chiye offers comprehensive OEM/ODM services: housing dimensions, impeller geometry tuning, powder-coating or galvanizing finishes, custom motor voltage/frequency options (e.g., 60Hz North American or Middle Eastern grids), specialized laser-cut mounting flanges, branded nameplates, and export seaworthy packaging.
Q6: How does Chiye ensure short lead times for bulk global procurement orders?
With a 20,000 square meter factory floor, automated CNC laser cutters, robotic welding cells, and an inventory of raw materials, Chiye manages production cycles efficiently.
