Silica Gels
Silica gels are essential adsorbents in many gas and compressed air drying applications. Compared to activated alumina and zeolites, these generally consume less energy in water desorption and are resistant to most acids. For standard applications, we provide silica gels of high water adsorption capacity, and our product portfolio also includes a water-resistant product and a type with indicator properties (deep orange > transparent color modification). With silica gels, the desorption of water adsorbed occurs at a temperature of approximately 150 °C / 300 °F.
