Uzbekistan 1,500㎡ Controlled Atmosphere Preservation Warehouse Project
Jinzhao Yuan Refrigeration successfully delivered a 1,500㎡ controlled atmosphere (CA) preservation warehouse project in Uzbekistan, providing a complete solution from system design to equipment supply and technical support for installation.
Uzbekistan is one of Central Asia’s most important fruit and vegetable producers, renowned for its grapes, apples, apricots, and pomegranates. The client, a large agricultural cooperative, sought to modernize their post-harvest storage infrastructure to reduce losses and capture higher-value export markets in Russia, the EU, and the Gulf region. Traditional cold storage was insufficient to maintain the freshness quality demanded by premium export buyers.
