Air Dryer Packages
HADETEC Air Dryer Packages are designed to deliver reliable, dry compressed air by effectively removing moisture and contaminants. Moisture removal is a vital step following air compression. By reducing the dew point of the compressed air, the system prevents corrosion, freezing, and premature wear of equipment and instrumentation.
HADETEC specializes in desiccant drying technologies, offering solutions tailored to demanding applications where reliable, ultra-dry air is essential. These packaged units ensure stable operation, protect downstream equipment, and support critical processes across a wide range of industrial applications. Each system is engineered as a complete, ready-to-install solution, integrating drying technology, filtration, controls, and safety components into a compact and efficient configuration. Packages can be supplied as standard units or fully customized systems, suitable for challenging environments, including severe ambient conditions like off-shore and hazardous areas.
Key features of HADETEC Air Dryer Packages include:
HADETEC Air Dryer Packages are based on two proven desiccant drying technologies: Pressure Swing Adsorption (PSA) and Temperature Swing Adsorption (TSA). Within the TSA range, advanced solutions such as Heat of Compression (HOC) dryers and zero-purge loss systems are available to further improve energy efficiency and reduce operational costs.
The main difference between these technologies lies in the regeneration method of the desiccant material. PSA dryers use the pressure differential between adsorption and regeneration and a portion of dry compressed air (purge air) to remove moisture, resulting in a simple and robust system suited for smaller capacities and high-temperature environments.
In contrast, TSA dryers use external heat or recovered heat (HOC) for regeneration, significantly reducing or eliminating the need for purge air. This makes TSA systems more energy-efficient (for HOC) and cost-effective for larger installations, particularly where minimal air loss and stable long-term performance are critical.
| Feature | PSA (Pressure Swing Adsorption) | TSA (Temperature Swing Adsorption) |
|---|---|---|
| Principle | Pressure-based adsorption / regeneration | Heat-based desiccant regeneration |
| Typical application | Small to medium flow rates | Medium to large flow rates |
| Dew point capability | Low | Low to ultra-low |
| Regeneration method | Uses dry purge air | Uses external heat (electric, steam, or HOC) |
| Purge air consumption | Moderate (continuous purge required) | Very low to near-zero (blower or heater purge) |
| Pressure stability | Fluctuating pressure due to cyclic pressurization/ depressurization and continuous purge air blow-off | Constant, stable pressure as regeneration is heat-based without significant depressurization |
| Cycle time | Short switching cycles (5–10 minutes) | Long regeneration cycles (8 hours) |
| Ambient suitability | Suitable for high temperature environments | Best suited for mild, controlled environments |
Reliable compressed air treatment is essential for ensuring system integrity and operational continuity. By combining proven desiccant drying technologies with tailor-made engineering, HADETEC Air Dryer Packages provide a dependable supply of clean, dry air for critical industrial environments.
