After more than two months of production and debugging testing, and third-party acceptance by SGS, we finally achieved the goal of ensuring the liquid nitrogen parameters for our customers. Producing 2L per hour with a purity of 99.999% is currently a precedent for high-purity liquid nitrogen.

Usually, users mainly use cooling capacity when using liquid nitrogen, and rarely use high-purity liquid nitrogen. But the customer has put forward new requirements for purity based on their own usage. We focus on meeting the customer's requirements, and ultimately design, produce, debug, and successfully pass third-party acceptance according to these requirements.

During this acceptance process, we did encounter some new problems, which actually provided us with room for improvement and made us aware of our shortcomings. However, after rectification, the final acceptance was passed. In the later stage of production, attention should still be paid to details, such as clear labeling and standardized wiring, in order to gain recognition from foreign customers.
