About
our company
Sanjing Cryogenic started its career, providing solutions to meet the vast requirement for industrial gases, accompanied by China's economic rocketing, in 2004. After its debut in the gas industry, it soon earned a reputation for its continuous efforts on technical improvements and quick reaction to after-sales service. As for now, Sanjing has already taken the lead as a local brand, still making its steps for the new realm of large-scale pumps, but never loses its grip on manufacturing mature products.
