Heatless Air Dryer
High-Quality Moisture-Absorbing System for Clean and Dry Compressed Air
Athena Instruments introduces the Heatless Air Dryer, a durable, twin-tower desiccant air-drying system designed for efficient removal of moisture from compressed air. Built with high-grade desiccant material, precision switching valves, and corrosion-resistant construction, these dryers ensure stable dew-point levels and long-lasting performance across industries such as pharmaceuticals, food and beverage processing, packaging, chemical plants, and industrial workshops.
Available in multiple airflow capacities up to 100 CFM with working pressure up to 12 bar, each system undergoes strict testing for adsorption efficiency, regeneration reliability, and continuous dry-air performance.
Key Features :
- High Moisture-Absorption Performance: Uses premium desiccants (Activated Alumina / Molecular Sieves) to ensure consistently dry air.
- Durable Dual-Tower Design: Strong powder-coated steel towers deliver long operational life in harsh environments.
- Low Dew Point Capability: Achieves dew points as low as –20°C to –40°C for moisture-sensitive applications.
- Reliable Safety & Regeneration Controls: Automatic switching valves and stable purge-air regeneration support uninterrupted operation.
- Easy Integration: Connects easily with standard compressors, pre-filters, and downstream air systems.
Applications
