After the replacement, even though the outdoor temperatures remained high, the cold storage consistently maintained a stable low temperature between -18°C and -25°C. The 15 cm panels acted as a robust barrier, keeping the heat firmly outside. The seafood, stored at an optimal temperature, retained its freshness and vitality as if it had just been caught.

What surprised Mr. Zhang even more was that the new panels not only provided excellent insulation but also significantly reduced energy consumption. Previously, maintaining the cold storage temperature was a considerable expense due to high electricity bills, but now the costs have noticeably decreased. With the freshness of the seafood guaranteed, Mr. Zhang's business has been thriving, attracting more and more customers. His seafood is not only popular locally in Qingdao but, with the support of BRD cold storage, is also being shipped nationwide, ensuring freshness on the tables of seafood lovers across the country!
