Which brands are considered the best for the air separation equipment used by various companies? This applies to major equipment in air separation such as air compressors, expanders, cryopumps, boosters, vaporizers, and process pumps
For air compressors and boosters, Mann is used; for expanders, Atlas or CryoStar are used. For liquid pumps, CryoStar or ACD will do, as well as Cryomac. It’s a heat exchanger rather than a vaporizer – we use Chatel, but Norton is also good, along with Mitsubishi from Japan. For process pumps, domestic or joint-venture products are generally suitable. If you want to use domestic equipment, leave it to professional companies such as Hangyang.
In China, the most influential companies are mainly these: Beijing Feida Jieneng, Wenzhou Ruiqi, Jiangsu Sujing, and Sichuan Meisail – all of them are used in the chemical industry. You can look them up online to learn more about them~~
It depends on the requirements of the poster; among brands with high quality, Linde Technology is the best. If cost-effectiveness is a priority, Kongkong Air and Chuankong Air are the most affordable options. Among domestic brands that are relatively good, Hangyang is a notable choice. Domestically produced centrifugal cryogenic liquid pumps have poor quality, while other domestic products are acceptable. For extremely large-scale technologies, it’s better to consider importing them.
