Intersorb® RG Carbon Dioxide Absorbent — 4 to 8 mesh Indicating + Non-indicating soda lime
Intersorb® Subsea 408 NI (non-indicating) | Intersorb® Subsea 408 WV (indicating)
Intersorb RG Carbon Dioxide Absorbent is a refinery grade product which removes low levels of acid gases such as CO2 and Sulphur Compounds from liquid and mixed phase hydrocarbon streams and petrochemical products. Ideally used in a polishing step after caustic wash or similar bulk cleaning steps to remove impurities.
- Particle size — 4-8 Mesh (3mm cylindrical granules)
- Higher CO2 capacity and longer duration compared to standard soda lime formulations
Application | Use:
Rebreather, Recreation Rebreather Diving, Commercial Diving, Military, Mine Safety Equipment.
Properties:
Intersorb® Subsea 408 is comprised of 3 mm cylindrical granules and has been developed specifically for use in saturation diving systems and other industrial applications where humidity levels can be significantly lower than in personal protection closed circuit applications. In these applications, Intersorb® Subsea shows a significant increase in CO2 absorption capacity compared with standard sodalime formulations.
Intersorb® Subsea has been tested to NATO test standard STANAG No 1411.
