Water buildup in compressed air systems causes millions of dollars of damage every year. Air Options Inc., Houston, TX, says its new line of dryers represent a significant advancement in the field of compressed air drying. The dryers are specifically designed to address the shortcomings of competing technologies by eliminating the need for complex CFCs and desiccants. The company says the dryers have a longer life expectancy, virtually no maintenance requirements, reduced operating costs, and a lower purchase price. In addition, their smaller footprint and tolerance for harsh conditions make them suitable for the crowded industrial environments where most compressors operate.
