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.



·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.
