Company DOLSIN
Almost a decade ago the company began MAGPROM cooperation with DOLSIN.
   DOLSINs a leading manufacturer of fillings such as Białecki rings, Raschig rings and Pall rings, which are the highest achievement in the field of column fillings. As column fillings, Białecki and Pall rings are widely used in chemical, petrochemical and coking industries, in power plants and in the widely understood environment protection, such as in water and sewage treatment technologies.

Pall rings
Raschig rings
Białecki and Pall rings are used:
•in the absorption and desorption processes;
•in rectification of continuous and periodic liquid-liquid extraction;
•for direct condensation of steam and cooling gases;
•as demister fillings (drop catchers) and air-oil separators;
•for separation of droplets and oily sewage;
•as static liquids and gases mixers;
•for air humidification;
•for treatment of drinking and boiler water, as well as water from the aerator;
•as deposits in biological sewage treatment plants for aeration of water and sewage;
•for the plate columns reconstruction;
•as a replacement for shelves, disc separators, Raschig rings in deaerators and desorbers.
We produce fillings in two versions:
1. wersion - as individual rings, designed to create loose layers (unordered form). It is most commonly used in the chemical and petrochemical industry, as well as in sewage treatment plants and for drinking and boiler water treatment. 

2.  wersion - in the form of packages, formed by the fusion of the rings (ordered form) for columns of any diameters and shapes, according to the parameters specified by the client. Application of the packages can further increase the efficiency of the column by reducing the flow resistance and energy consumption. Moreover, the organised form facilitates the exchange and regeneration of the fillings. 
The rings are made of such materials as:
metals - various types of steel, copper, aluminium, titanium and others.
plastics - polypropylene (PP), polyethylene (PE), polyamide (PA), PVC and PVDF, as well as glass fibre reinforced plastics, such as POLYFORT.
