Description
WSAG is a specially formulated silica‑alumina adsorbent offering enhanced resistance to water ingress while maintaining high adsorption capacity and mechanical strength. It is suitable for continuous operation in air separation units, compressed air drying systems and gas purification lines where conventional desiccants may lose effectiveness.

Applications

• Drying of air separation and compressed air systems
• Gas purification and acetylene (C₂H₂) removal in liquid oxygen and nitrogen production
• Moisture adsorption and catalyst support in petrochemical, power generation and brewing processes
• Protective top layer for silica gel or silica‑alumina beds under wet conditions

Why choose WSAG from BERG Kompressoren GmbH?

• Water‑resistant formulation for high‑humidity or liquid‑contact environments
• Consistent, high adsorption capacity across humidity ranges
• High mechanical strength for extended service life
• Compatible with systems designed for silica gel or silica‑alumina adsorbents

Standard packaging & storage

• Standard packaging unit: approx. 25 kg
• Store in a dry, sealed environment to preserve adsorption capacity
