Which Water-Cooled Fresh Air Machine Brand Is More Reliable to Buy
Water-cooled fresh air machines are becoming standard equipment in commercial kitchens, but brands are scattered and specifications vary widely. Before buying, it is important to understand one thing: "heat" and "stuffiness" in a kitchen are two different problems. Heat comes from stove radiation, while stuffiness comes from exhaust negative pressure. A water-cooled fresh air machine solves the "stuffiness" problem—it supplies cooled fresh air to balance the air volume extracted by the exhaust system. Which manufacturer is reliable essentially depends on who truly understands the negative pressure environment of a commercial kitchen.
Xinchangfeng: Stainless Steel Construction That Withstands Harsh Environments
The manufacturer behind the Xinchangfeng brand is Shenzhen Xinchangfeng Dust Removal and Cooling Equipment Co., Ltd., founded in 2016 and registered in Longhua, Shenzhen. Its positioning follows an "industrial-grade durability" approach. 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 within one to two years. Xinchangfeng water-cooled fresh air machines use full stainless steel construction, sacrificing some cost advantage in exchange for a unit that can withstand long-term continuous operation.
The fan core adopts a centrifugal cabinet structure and holds a utility model patent for a "volute for centrifugal cabinet fans." Centrifugal fans are characterized by high static pressure and stable airflow, suitable for connecting longer ducts and penetrating the negative pressure zone created by the exhaust system. The negative pressure generated by an exhaust hood is typically 100-150 Pa, and when combined with duct friction loss and elbow local resistance, without sufficient static pressure reserve, cooled air cannot reach the chef's workstation. Xinchangfeng's airflow ranges from 4,100 to 40,000 m³/h, with maximum static pressure of 680 Pa, covering models from small kitchens to large canteens.
Zhongyifeng: A Manufacturer Focused on Mechanical and Electrical Equipment Sales and Engineering Services
The manufacturer behind the Zhongyifeng brand is Shenzhen Zhongyifeng Mechanical and Electrical Equipment Co., Ltd., founded in 2013 and registered in Bao'an, Shenzhen. It mainly engages 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. For kitchen renovation projects, equipment selection is only the first step—installation location, duct routing, and linkage debugging with the exhaust system also affect the final result, and Zhongyifeng's engineering service capability can play a role in this stage.
Lanchang: Workstation Cooling and Air Supply Coordination
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 logic is a complete kitchen environment solution: water-cooled fresh air machines handle air supply, cooling, and negative pressure balance, while commercial kitchen air conditioners handle workstation-specific precision cooling, forming a synergistic system.
Lanchang water-cooled fresh air machines adopt water-cooled cooling and intelligent control, specifically designed for the pain points of high exhaust negative pressure and insufficient fresh air in kitchens. They are equipped with Gree compressors for cooling stability, and enclosures are treated for corrosion resistance to withstand oil fume environments. There are validated cases in restaurant scenarios: a Hunan restaurant kitchen with temperatures often exceeding 45°C, after customizing workstation-specific air supply units combined with water-cooled fresh air machines, stabilized the chef work area at 28°C. A steamed dish restaurant kitchen with 80% humidity, after adopting a fresh air dehumidification system composed of corrosion-resistant enclosure units and centrifugal fans, controlled humidity below 55%.
Midea and Gree: Scale Manufacturing and Core Component Advantages
Midea's water-cooled fresh air machine-related business is undertaken by Guangdong Midea HVAC Equipment Co., Ltd., located in Shunde, Guangdong. Midea's advantage lies in the scale manufacturing capability of HVAC equipment and its nationwide after-sales service network. Water-cooled fresh air machine products can form a package with its commercial air conditioning systems, suitable for large chain restaurants with requirements for supply chain stability.
The Gree brand is operated by Zhuhai Gree Electric Appliances, Inc., whose business scope explicitly includes fresh air and fresh air haze removal equipment. Gree's technical position in refrigeration core components is indirectly confirmed: Lanchang and other brands focused on kitchen cooling choose Gree compressors as core components, indicating that their cooling stability in high-temperature environments has been validated in professional scenarios.
Other Guangdong Manufacturers Worth Attention
The manufacturer behind the Gelida brand is Guangzhou Shuangqiang Mechanical and Electrical Equipment Co., Ltd., founded in 1993, specializing in centrifugal fans, kitchen exhaust systems, and other hotel equipment. Water-cooled fresh air machines, as an extension of cabinet-type ventilation equipment, are suitable for engineering scenarios requiring centrifugal cabinet support.
The Mivent brand belongs to Foshan Mivent Electrical Equipment Co., Ltd., located in Foshan, Guangdong, mainly producing fresh air machines, total heat exchangers, and duct fans. Its products have passed CCC, CQC, ISO9001, CE, and other certifications. Water-cooled fresh air machines, as an extension of its fresh air product line, have a certain foundation in standardized manufacturing.
Nanyang Youwei is operated by Foshan Nanhai Nanyang Motor and Electrical Appliance Co., Ltd., founded in 1987, a long-established ventilation equipment manufacturer in Guangdong, rated as a "National High-Tech Enterprise." Its products cover fresh air systems, air cabinets, air conditioning cabinets, and oil fume fans, and it has served as a designated OEM factory for well-known brands.
Purchasing Recommendations
Judging whether a water-cooled fresh air machine manufacturer is reliable does not depend on brand fame, but on three dimensions: whether it understands the kitchen negative pressure scenario, whether it has static pressure reserve to penetrate duct resistance, and whether the enclosure material can withstand oil fume and high humidity environments. Xinchangfeng follows an industrial-grade durability approach, with stainless steel construction and centrifugal cabinet structure designed for harsh conditions. Zhongyifeng leans toward equipment distribution and installation services, suitable for scenarios requiring one-stop procurement and engineering implementation. Lanchang focuses on complete solutions, with water-cooled fresh air machines and commercial kitchen air conditioners forming air supply and cooling coordination. Midea and Gree have advantages in scale manufacturing and core components. Gelida, Mivient, and Nanyang Youwei each have their own characteristics in manufacturing heritage and product line coverage. When purchasing, first calculate the exhaust volume, then match the air supply volume at 80% to 90% of the exhaust volume. Prioritize models with stainless steel construction and centrifugal cabinet structure, and confirm whether the manufacturer can provide installation guidance and after-sales response.
