几个月前青岛有位张总，做海鲜贸易的，他的生意一直不错，找到我们的时候也是遇到了不小的问题。张总冷库一开始使用的是传统喷涂聚氨酯冷库，刚开始没什么大问题。随着生意越做越大，问题慢慢就暴露出来了。

A few months ago, Mr. Zhang from Qingdao, who is in the seafood trading business, encountered some significant issues despite his business doing well initially. Mr. Zhang's cold storage facility was originally built using traditional spray polyurethane insulation. At first, everything seemed fine, but as his business expanded, problems started to surface.

青岛入夏也是格外炎热，那阵子，由于传统喷涂聚氨酯冷库的保温效果不佳，冷库内的温度频繁波动。早上打开冷库，发现不少成本高，价值高的海鲜已经不再新鲜，有些甚至开始变质，正常售价一下子量也卖不出去，也不舍得低价出售，结果就是损失了不少钱。后来，张总经过朋友介绍了解到必发集团的产品口碑，决定把冷库板换成必发集团15公分厚的机制聚氨酯冷库板。这一换，效果简直是立竿见影！

Qingdao can get extremely hot in the summer, and during that period, the poor insulation performance of the traditional spray polyurethane cold storage led to frequent temperature fluctuations inside the facility. When he opened the cold storage in the morning, he found that many of the high-cost, high-value seafood products were no longer fresh, and some had even begun to spoil. As a result, he couldn't sell them at their usual prices, nor was he willing to sell them at a loss, leading to significant financial losses. Later, through a friend's recommendation, Mr. Zhang learned about the positive reputation of BRD products and decided to replace his cold storage panels with BRD's 15 cm thick panels. The results were immediate!

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!
