Plastic Ralu Ring is an improved pall ring, it is the fourth-generation packings which have prominent characteristics compared to the other types. Its open structure ensures a regular flow through the packed bed resulting in a minimal pressure drop.
Plastic Ralu Rings are featured with high free volume, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high mass transfer efficiency and so on, and the application temperature in media ranges from 60°C to 280°C.
Plastic ralu ring is widely apply in all kinds of separation, absorption and desorption device, atmospheric and vacuum distillation device, decarburization and desulfurization system, ethylbenzene, iso-octane and toluene separation.
Package: Plastic bags. Working Temperature: 60-150℃
