Refrigerated Air Dryers
Annair Silverline Heatless Air Dryers are compact, lightweight, and engineered to deliver ultra-dry air for critical process and instrumentation applications. With fully automatic operation, low maintenance, and robust aluminium construction, they provide a reliable and efficient solution for maintaining compressed air quality in compliance with ISO 8573-1 standards.
Salient Features:
1. No External Heat Required
🔹 Operates using purge air from the compressed air system—no heaters or electrical regeneration.
2. Compact & Space-Saving Design
🔹 Designed for installations with limited space; suitable for wall-mounted or floor-mounted setups.
3. Tower Construction: High-Strength Aluminium
🔹 Corrosion-resistant aluminium towers for durability, lightweight handling, and thermal efficiency.
4. Capacity Range: 10 to 60 CFM
🔹 Covers small to medium-duty applications in labs, CNC machines, packaging, and instrumentation.
5. Pressure Dew Point as Low as -40°C to -70°C
🔹 Delivers ultra-dry air for critical applications in electronics, pharmaceuticals, and food processing.
6. Twin Tower Design with Desiccant Beds
🔹 Alternating operation ensures continuous drying—one tower dries while the other regenerates.
7. Long-Life Desiccant Media
🔹 Uses high-efficiency desiccants like activated alumina or molecular sieves with low dusting and high adsorption capacity.
8. Fully Automatic Operation
🔹 Equipped with timer-based or PLC-controlled cycle logic for seamless switching between towers.
9. Integrated Filtration Options
🔹 Pre-filters and after-filters (optional) protect desiccant and ensure oil and particle removal in line with ISO 8573-1 standards.
10. Low Maintenance Requirements
🔹 Simple design with no heaters or blowers; only periodic filter and desiccant replacement required
