Plastic VSP ring's full name is plastic very special packing, and it has reasonable geometric symmetry. The inner arc are folded evenly along the axial direction and replaced alternated arranged. This design contributes a continuous surface for extremely high voidage and evenly distribution. Compared with pall Ring, its flux efficiency is 15-30%, its pressure drop is reduced by 20-30%.
As a leading manufacturer of plastic VSP rings, we have the expertise in the operational requirements and compliance and standards of many different industries across the globe, we can help you choose the best product for your requirements.
Materials: PE, PP, RPP, PVC, CPVC, PVDF, etc.
Large flux and low pressure drop
Strong resistance to chemical corrosion
Energy saving and easy to operate
High separation efficiency
With lowest pressure drop among comparable packings, plastic VSP ring can be used in packed towers for the stripping (removal) of volatile organic carbons (VOCs) and other gases, in scrubbers at rendering and municipal wastewater treatment plants achieving over 99.8% hydrogen sulfide absorption, in degassing applications to remove carbon dioxide or radon and in aerators to oxygenate water for aquaculture applications, etc.
