While the target of an adsorbent product can be any kind of foreign contaminant, like gases, vapors, oxygen, or odors, the most common contamination is moisture. Moisture is a primary cause of damage in products, during transportation, and in general packaging. The Flow Dry line of available desiccants is engineered to deliver the highest drying capacity for any given application without sacrificing cost-effectiveness or system operating reliability. Moisture control was the original thrust for products as the company created its line of products used in Automotive Air Conditioning systems. These products keep the refrigerants dry and eliminate system failure due to acid formation, corrosion, and system blockage.
