General Characteristics:

CALSIT is synthetic zeolite of type 5A having pore size of 0,5 nm. Molecular sieves are crystalline aluminosilicates of alkali metals or alkaline earth metals. They have a three-dimensional crystal lattice with basic structural units of SiO^-₄ a AlO^-₄ tetrahedrons so arranged, that regular alternating cavities are formed. The size of the intracrystalline cavities and of the intake openings - the pores to the cavities - are characteristic for the individual types of molecular sieves.
CALSIT has 60 - 70% of sodium ions exchanges by calcium. Its chemical composition in dehydrated state is given by the formula: CaO . Na₂O . Al₂O₃ . 2 SiO₂.

  RAK₄₃ - equlibrium adosrption capacity
This parameter is determining the capability of the zeolite to adsorb water vapour from air at 25° C and with 43% of relative humidity. The value is expressed as; water grams per 100 grams of anhydrous zeolite.
  V 30 - cylindrical extrudates with 3,0 mm diameter

Packaging and Storage:

Zeolites are packed and supplied in 20 litres or 200 litres metallic packages. The maximum water content in granulated packed products is 1,5% wt.
