Cold Box

Based on different processes, there are mainly two types of fractionation column single stage column and double stage column.
The fractionation column designed and manufactured by us has a superior systematic performance, flexible and stability The purity and recovery both have been equivalent with the most advanced international technologies. We equip plate-fin type heat exchanger and full aluminium structure to main part of internal components of the cold box, which is close sealed and filled in gas to preserve pressure. Thus the cold loss caused by heat in leak is reduced to large extent. Cold box below 6000Nmh can be assembled within our workshop, which could reduce work load at customer's work site and supplied as a packaged unit.
