In particular, the liquid spreader should be cleaned and no debris should be allowed to fall into the diffuser. It is necessary to ensure that the diffuser is detached from the diffuser before entering the tower.
Vulnerable and volatile parts, such as Plastic Raschig Ring, nuts, connecting ribs and other small parts, should be stored in the warehouse according to the standard according to the standard.
