Proviseur de solution de stockage à froid en porcelaine
1. Project Overview
Client: China Agricultural Wholesale Market Holding Co. (State-owned Logistics Leader)
Emplacement: Pingxiang City, Jiangxi Province, Chine
Total Area: 11,000㎡
Completion Date: May 2020
Cold Storage Type: Agro-product cold chain logistics warehouse
This project was developed in collaboration with China Agricultural Wholesale Market Holding Co., serving as a regional distribution and storage hub for fresh produce, frozen food, and other agricultural goods. The facility was designed and built by Haoshuang Refrigeration and includes three floors of low-temperature storage chambers to support a wide range of cold chain demands.
