Adsorption dryer technology

Adsorption dryers remove moisture from compressed air by passing it through a desiccant that absorbs water vapor. Once saturated, the desiccant is regenerated using a portion of the dried purge air. The PH 55-420 HE range uses this heatless technology to achieve a consistent pressure dew point of -70°C (-94°F) with minimal purge air loss. Designed for efficiency, these models provide ultra-dry air while keeping energy use and costs low, making them ideal for critical applications that require reliable moisture control.

Discover the key features of the PH 55-550 S

The PH 55-420 HE range combines advanced features for top performance and efficiency. It includes energy-saving technologies like compressor synchronization and purge nozzle optimization to reduce operating costs. The unique valve design ensures minimal pressure drop and optimal purge air expansion, cutting purge losses. These dryers operate quietly and achieve an ultra-low dew point of -70°C (-94°F) using high-efficiency molecular sieve desiccants. The spring-loaded design prevents desiccant crushing, while counter-current regeneration boosts energy efficiency. With optional wall-mounting kits, easy-to-service desiccant bags, and the Purelogic controller for precise monitoring, this range delivers reliable, cost-effective air drying.
