Random Packing--Plastic Pall Ring

Detailed Product Description

 

Plastic Pall Ring detail

Plastic is versatile. This product was invented on the basis of Plastic Rasching Ring. Both of them have similar cylindrical dimensions but the Plastic Pall Ring has two rows of punched out holes, with fingers or webs turned into the centre of the cylinder, which significantly increases the performance of the packing, in terms of throughput, efficiency and pressure drop.

 

Advantages:
It has features such as 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. 

 

Application:

Absorption, scrubbing, and stripping services. Versatile alternative to metal Pall rings.
 

A variety of different sizes of products provide the ability to optimize capacity and efficiency based on different application requirements, and the application temperature in media ranges from 60to 150.
