HADETEC Temperature Swing Adsorption (TSA) air dryer packages are designed for high-capacity applications where stable pressure, ultra-low dew point and minimal compressed air loss are key requirements. These systems regenerate the desiccant using heat, rather than relying on large amounts of purge air, making them particularly suitable for continuous, large-scale industrial operations.
In standard TSA configurations, desiccant regeneration is achieved by applying external heat sources such as electric heaters or steam. This significantly reduces purge air consumption compared to heatless systems and ensures stable, long-cycle operation with consistent dew point performance. For further optimization, HADETEC offers advanced TSA configurations:
- Heat of Compression (HOC) dryers: These systems utilize the available heat from the compressor discharge air to regenerate the desiccant. By recovering and reusing this energy, HOC dryers eliminate the need for external heating, resulting in highly energy-efficient operation with minimal additional power consumption.
- Zero-purge loss dryers (closed-circuit systems): In this configuration, the regeneration process takes place in a closed loop, preventing the loss of compressed air during operation. This results in no purge air consumption, maximizing system efficiency and reducing operational costs, especially in high-capacity installations.
TSA air dryer packages are ideally suited for:
- Large air flow volumes
- Energy-optimized systems (HOC)
- Applications requiring stable pressure or very low dew points
- Continuous operation in demanding industrial environments
A typical TSA Type Air Dryer Package includes
- Pre-filtration / coalescing filter
- Twin adsorber vessels filled with high-performance desiccant
- After filtration / particle filter
- Heating system (electric or steam) for desiccant regeneration (for heated TSA systems)
- Blower unit for regeneration air circulation (for blower purge configurations)
- Heat recovery system (for Heat of Compression (HOC) dryers)
- Closed-loop regeneration system (for zero-purge loss configurations)
- Interconnecting piping and automatic switch-over valves for adsorption and regeneration cycles
- Field instruments including pressure, temperature, and flow measurement
- Dewpoint analyzer for continuous dewpoint monitoring
- Local control panel with indication, control & HMI interface compatible with plant DCS
