Achieve consistent low dew points (to -40°C, customizable to -70°C) for your critical processes.
Adsorption Air Drying for Oil-Free Compressed Air Systems
Adsorption Dryers
Find the right technology for your oil-free system based on your priorities for initial cost, energy efficiency, and performance.
Key Performance Ranges: Heatless & Heated Regeneration
DS-H Series: Heatless Regeneration
Reliable drying with proven PSA technology. Uses a portion of dried air for regeneration. Best for simplicity and lower upfront cost.
- Continuous dry air supply
- Robust and easy maintenance
- Regen. Air Usage: ~13-15%
DS-R Series: Heated Regeneration
Reduces purge air needs compared to heatless dryers. Uses a heater to improve regeneration efficiency and lower running costs.
- Lower compressed air consumption
- Good balance of cost & efficiency
- Regen. Air Usage: ~7-8%
Key Performance Ranges: Blower Purge Regeneration
DS-E Series: Blower Purge (Micro-Consumption)
High energy savings. Uses a blower and heater with ambient air, preserving almost all your compressed air for production.
- Significant energy efficiency gain
- Minimal process air loss
- Regen. Air Usage: ≤ 2-3%
DS-F Series: Blower Purge (Zero Loss)
Maximum efficiency and sustainability. Eliminates compressed air use for regeneration via blower, heater, and closed-loop cooling.
- Ultimate energy savings
- Ideal for high energy cost environments
- Regen. Air Usage: 0%
Key Performance Ranges: Heat of Compression Regeneration
DS-G Series: Heat of Compression (Micro-Consumption)
Leverages 'free' heat from your oil-free compressor. Drastically cuts external energy needs for very low operating costs.
- Utilizes compressor waste heat
- Requires compatible compressor (Inlet Temp: ≥ 100°C)
- Regen. Air Usage: ≤ 2-3%
DS-Y Series: Heat of Compression (Zero Loss)
Peak energy efficiency. Uses compressor heat and advanced cooling for zero loss of processed compressed air during regeneration.
- Eliminates purge air loss
- Lowest OPEX for compatible systems (Inlet Temp: ≥ 110°C)
- Regen. Air Usage: 0%
Addressing Critical Needs in Oil-Free Air Systems
Oil-free compressed air is vital for sensitive industries. However, residual moisture can still compromise processes and equipment if not adequately addressed.
Prevent Microbial Contamination
Moisture in oil-free systems can foster microbial growth, a critical concern in food & beverage, pharmaceutical, and medical applications. Our dryers ensure a hygienic air supply by maintaining extremely low dew points.
Ensure Process Stability
Fluctuations in air quality due to moisture can disrupt sensitive processes. HANDE dryers deliver consistent, low dew points, ensuring the reliability of your pneumatic controls, instrument air, and product conveying systems.
