Refrigeration filter driers typically consist of a shell made of steel or copper, which contains a filter element made of a porous material, such as activated alumina, molecular sieves, or blend of both. The filter element acts as a barrier that captures and removes contaminants from the refrigerant as it flows through the filter drier.
Combining flexibility with reliability, Rotary Dryers handle a vast range of materials ranging from pharmaceutical grade sweeteners to phosphate rock. The design permits the use of the highest possible drying temperatures (where product allows) and is not sensitive to fluctuations in throughput or particle size.
