Drying of water**-Catch All  filters will use of the desiccant particles in the water cooling system lock, hybrid desiccant adsorption of water particles can be much drier than normal, so that it can avoid security expansion valve suffered by the ice block.

Impurities **- the oxide within the refrigeration system, welding slag, sludge and other debris will affect the compressor, solenoid valve, expansion valve and other important components, must be removed.
Catch All  dry filter to filter the impurities in the most efficient manner and will not have a huge buck, which have benefited from its large area and
