 PRODUCTS DSN DOLSIN

DSN DOLSIN is a leading manufacturer of Pall rings, Bialecki's rings and Rashig's rings fillings, which are the supreme achievement in the field of column fillings.

Pall's rings, Bialecki's rings, as the column fillers are very widely used in the chemical, petrochemical, coke industries, in thermal power plants and general environmental protection, among others in water treatment and sewage treatment technologies.

Pall's rings and Bialecki's rings are used:
• in absorption and desorption processes; • in rectification of continuous and periodic liquid-liquid extraction;
• for direct condensation and cooling of gases;
• as a filler of demisters (splash heads) and air oil separators;
• for the separation of droplets and oily waste water;
• as static mixers for liquids and gases;
• for air humidification;
• for air humidification;
• for the treatment of drinking water and boiler water, and in aerators;
• as a deposits in biological wastewater treatment plants for aeration of water and wastewater;
• for the reconstruction of the plate columns;
• to replace plates, disc distributors, Raschig's rings in degassers and desorbers.

We produce fillings in two options:




option 1 - as single rings, designed to create cover layers (unstructured form). This is the most commonly used form in the chemical, petrochemical industries, wastewater treatment plants and for drinking water and boiler water treatment.








option 2 - in the form of packages, formed by ring welding (structured form) for any diameter and shape of the column, according to the parameters indicated by the customer. The use of the packages increases the efficiency of the column performance by reducing the flow resistance and reducing energy consumption. In addition, the structured form facilitates the replacement and regeneration of the fillings.

Rings are made of materials such as: metals - various grades of steel, copper, aluminium, titanium and others. plastics - polypropylene (PP), polyethylene (PE), polyamide (PA), PVC and PVDF and of glass fibre reinforced materials such as POLYFORT.
