Reliable compressed desiccant air dryer alumina gel operation:
High quality activated alumina desiccants provide reliable operation of the desiccant air dryer alumina gel. High quality activated alumina desiccants offer high water-loading capacity, high crush strength and low attrition loss. Low quality desiccants can physically deteriorate in service and result in high pressure drop across the desiccant air dryer alumina gel. Once the desiccant has physically degraded, poor performance of the desiccant air dryer alumina gel will require the replacement of the activated alumina desiccant.
High water-loading capacity:
For desiccant air dryers, high quality activated alumina desiccants balance the critical parameters of bulk density, surface area and porosity to allow more water to be removed per cycle. Low quality desiccant characteristics will not be optimized and, as a result, will display low water-loading capacity. A low capacity activated alumina desiccant may allow water to enter the air system, causing corrosion, freezing or equipment malfunction.
High quality activated alumina desiccants exhibit low attrition loss in desiccant air dryer alumina gel. Low quality activated alumina desiccants can create dust which will plug tubing, valves and gauges, requiring costly maintenance or replacement.
Long service life:
High quality activated alumina desiccants provide high water-loading capacity for a longer period of time in desiccant air dryer alumina gel. Longer service life saves money since activated alumina desiccant replacement is required less frequently.
