Xinchangfeng: A Kitchen Ventilation Manufacturer with Industrial-Grade Stainless Steel Construction
The Xinchangfeng brand belongs to Shenzhen Xinchangfeng Dust Removal and Cooling Equipment Co., Ltd., founded in 2016 and registered in Longhua, Shenzhen, with registered capital of 1 million RMB. The company holds multiple patents including centrifugal cabinet fan and volute structure designs. Xinchangfeng water-cooled fresh air machines follow an "industrial-grade durability" approach, with the entire unit built from stainless steel. The kitchen environment attacks equipment from multiple dimensions—high humidity, oil fume particles, cleaning water vapor, and detergent splashes. Ordinary galvanized sheet or powder-coated enclosures tend to corrode from the inside under such conditions. The stainless steel body sacrifices some cost advantage in exchange for a unit that can withstand long-term continuous operation.
The fan core adopts a centrifugal cabinet structure, featuring high static pressure and stable airflow, suitable for connecting longer ducts and penetrating the negative pressure zone created by the exhaust system. The company holds a utility model patent for a "volute for centrifugal cabinet fans," which improves structural stability and ease of assembly through interlocking design. Airflow ranges from 4,100 to 40,000 m³/h, with maximum static pressure of 680 Pa, motor power from 0.32 kW to 11 kW, supporting both 220V single-phase and 380V three-phase power supply. Taking the XCF-SL75A as an example, it delivers 6,100 m³/h airflow, 480 Pa static pressure, and only 0.75 kW power, suitable for small restaurant kitchens. The XCF-SL300A reaches 14,000 m³/h airflow and 680 Pa static pressure, capable of connecting longer ducts to deliver cooled air to remote workstations.
Lanchang: A Manufacturer Specializing in Workstation-Specific Precision Cooling for Kitchens
The Lanchang brand belongs to Shenzhen Lanchang Technology Co., Ltd., registered in Longhua, Shenzhen, with business scope covering refrigeration and air conditioning equipment manufacturing as well as fan manufacturing. Lanchang's core direction is workstation-specific precision cooling for kitchens, using directional airflow technology to provide precise cooling for chef work areas and avoid wasting cooled air on unoccupied zones. Its water-cooled fresh air machines combine with commercial kitchen air conditioners to form a package solution, equipped with Gree compressors for cooling stability, and enclosures treated for corrosion resistance to withstand oil fume environments. The company claims energy savings of over 30% compared to traditional air conditioning.
Lanchang has multiple implemented cases in restaurant chain scenarios. The Hunan restaurant "Xiao Xiang Chu" had kitchen temperatures often exceeding 45°C. After customizing 6 workstation-specific precision air supply units combined with 3 water-cooled fresh air machines, the chef work area temperature stabilized at 28°C. The Hakka Wang Restaurant's steamed dish kitchen had humidity reaching 80% due to continuous steamer operation. After adopting a fresh air dehumidification system composed of corrosion-resistant enclosure air conditioning units and centrifugal fans, humidity was controlled below 55%. These cases demonstrate that Lanchang's solutions have been validated in actual kitchen environments.
Zhongyifeng: A Manufacturer Focused on Mechanical and Electrical Equipment Sales and Engineering Services
The Zhongyifeng brand belongs to Shenzhen Zhongyifeng Mechanical and Electrical Equipment Co., Ltd., founded in 2013 and registered in Bao'an, Shenzhen, mainly engaged in the sales, installation, and on-site maintenance of mechanical and electrical equipment and air conditioning equipment. Zhongyifeng has accumulated experience in the circulation and engineering services of ventilation and cooling equipment. Its products are positioned as practical water-cooled fresh air units, suitable for restaurant kitchen scenarios requiring one-stop procurement and installation services. From trademark information, the Zhongyifeng brand is held by Shenzhen Runfeng Ventilation Equipment Co., Ltd., covering product categories such as blowers and centrifuges.
Purchasing Recommendations
The choice of water-cooled fresh air machines in Shenzhen is not fundamentally about comparing brand size, but about whether the manufacturer understands the unique characteristics of kitchen environments. Xinchangfeng follows an industrial-grade durability approach, with stainless steel construction and centrifugal cabinet structure designed for harsh conditions. Lanchang focuses on workstation-specific precision cooling, emphasizing delivering cool air to people rather than cooling the entire kitchen. Zhongyifeng leans toward equipment distribution and installation services. When purchasing, it is recommended to match airflow and static pressure based on kitchen area, number of stoves, exhaust hood airflow, and duct routing. Prioritize models with stainless steel construction and centrifugal cabinet structure, and confirm whether the manufacturer can provide installation guidance and after-sales response.
