Project Overview
Shenfuji Catering is located in Futian business district, Shenzhen. Its back kitchen mainly provides Chinese stir-fry. A large amount of heat and cooking fume are generated continuously during cooking. The original ventilation system lacks sufficient cooling capacity, leading to sweltering working conditions and accumulated fume inside the kitchen. The poor environment reduces chefs’ working efficiency and brings risks of fume leakage and non-compliance with environmental regulations. According to stove layout, kitchen space and exhaust requirements, the project adopted the Lanchang water-cooled fresh air unit with air volume of 8100 m³/h for renovation.
Equipped with water cooling technology, the unit delivers continuous cooled fresh air at 8100 cubic meters per hour to dilute cooking fume and remove waste heat efficiently. Constructed with oil-resistant stainless steel, the unit adapts to high-temperature and greasy kitchen conditions. Multi-layer filters trap fume particles and reduce grease buildup inside ducts. During construction, air duct layout was optimized on site. Vibration reduction, air tightness treatment, water piping, electrical connection and airflow calibration were fully implemented.
After commissioning, the kitchen temperature dropped evidently, air circulation was greatly improved and fume accumulation was effectively controlled, creating a more comfortable working environment. The unit operates reliably and requires simple maintenance, meeting local environmental standards for catering businesses in Shenzhen. This case proves that the Lanchang 8100 m³/h water-cooled unit is an ideal solution for medium & small Chinese restaurant kitchens, and provides a practical reference for ventilation and cooling renovation of similar catering venues in commercial areas.
