- Compact design with modular flexibility
Lightweight and space-saving, this desiccant air dryer allows convenient transport and installation. Each cartridge is under 30L, exempt from pressure vessel regulations, and achieves twice the drying performance of conventional twin-tower systems using only one-third the desiccant volume. The system design prevents channeling effects, ensuring consistent performance.
- High-performance adsorption
Uses a composite molecular sieve for enhanced adsorption efficiency with instantaneous absorption and discharge. Built with aluminum alloy, the housing resists corrosion and supports easy maintenance. Units can handle air flows from 0.5 to 30 m³/min and scale up through parallel configuration for large-capacity systems.
