Project Overview
Most local fast-food stir-fry restaurants in Nanjing feature compact back kitchens of 15 to 22 square meters with 2–3 high-heat woks. Confined and poorly ventilated, these kitchens suffer from persistent high temperature and heavy lampblack in summer. A convenience fast-food restaurant in Qinhuai District, Nanjing owns an 18-square-meter kitchen with three stir-fry stoves operated by three chefs in shifts. The store previously installed an ordinary household wall-mounted air conditioner, which struggled with extreme stove heat, grease buildup and negative exhaust pressure. After only one and a half months, thick oil clogged its filter and evaporator, crippling cooling performance. Temperatures at cooking stations stayed above 43°C all day long. Working under sweltering conditions, chefs frequently suffered heat discomfort and resigned, lowering table turnover and bringing heavy operational pressure to the restaurant.
After comparing multiple cooling devices, the restaurant adopted a targeted station cooling solution with Lanchang 2HP commercial kitchen air conditioner. Lanchang’s engineers conducted on-site surveys to fit the kitchen’s constraints: limited floor height, narrow space and constant lampblack. The compact wall-hung 2HP high-static-pressure unit saves precious operating room. Equipped with two directional air ducts, it delivers cool air straight to chefs’ standing zones away from exhaust hoods, preventing cold air from being sucked away and wasted.
Fitted with a T3 high-temperature resistant compressor, the unit maintains stable cooling even under ambient temperatures up to 58°C. Its 5-layer composite oil-proof filter and nano oil-repellent heat exchange fins drastically cut grease adhesion. Daily maintenance only requires rinsing the filter, eliminating frequent full disassembly deep cleaning. The whole machine is built with anti-rust cold-rolled steel, resisting moisture and oil corrosion, ideal for Nanjing’s humid, muggy plum rain season. The variable-frequency energy-saving system adjusts output power automatically, cutting monthly power consumption by 18% compared with old household air conditioners.
Post-installation tests show station temperature dropped steadily from 43°C to 26°C, creating a comfortable working environment even during peak meal hours. Chefs’ working efficiency improved significantly, lifting lunch and dinner table turnover by 16% and resolving high staff turnover completely. Supported by Lanchang’s local after-sales service network in Jiangsu, the unit enjoys a 3-year full-machine warranty and a 5-year warranty on core components. 24-hour on-site maintenance service is available across Nanjing to avoid disruptions during peak business hours.
The Lanchang 2HP model perfectly fits small back kitchens of fast-food restaurants, casual diners, takeout stir-fry shops and noodle houses with 1–3 stoves across Nanjing. Thanks to its compact size, powerful anti-grease performance and energy-efficient cooling, it has become the mainstream renovation solution for micro catering kitchens in Nanjing, winning wide recognition from local fast-food operators.
