Dehydration of compressed air on brake systems of heavy- and medium-duty trucks, buses and trains
Shanghai desikenshi Molecular sieve CO.,Ltd
Melocular sieves 4A
Melocular sieve 4A is an alkali alumino silicate,it is the sodium form of the type A crystal structure.
Molecular sieve 4A has an effective pore opening of less than 4angstroms and exclude those larger.Such adsorbable molecular include simple gas molecular such as oxygen,nitrogen,carbon dioxyde and straight chain hydrocarbons.Branched chain hydrocarbons and aromatics excluded.

Recommended application:
·drying and removing of CO2 from natural gas,LPG,air,inert and athmospheric gases,etc.
·removal of hydrocarbons,ammonia and methanol from gas streams(ammonisa syn gas treating)
·in the air break uints of buses ,trucks and locomotives.
·dehydration of electronic element,pharmaceutical,food,etc.
Packing:
·55 gallon air-tight iron drum,and each drum has inner PE bag.
·25 kg/carton,and each carton has inner PE bag.
·other packing according to your requirement.
Instruction: prevent molecular sieve from exposing directly to the air.
Waring: molecular sieve adsorption activity is an exothermic reaction,any contact to human body is dangerous.
