8. Diving Rebreathers
Proven product supplied to most of the world’s major navies
Formulated for ultimate performance and firmly established as the leading diving absorbent
Irregular granular form ensures superior packing in all diving canisters
Hard granules resist dust formation thus maintaining reproducible and minimal breathing resistance

9. Diving Rebreathers
High porosity and large surface area to volume ratio for the most efficient removal of CO2
Different granular sizes available to suit design requirements for a variety of rebreather manufacturers
Maintains high efficiency even in hostile environments (temperatures as low as -2°C or pressures up to 30 bar)

10. Oxygen Generators

11. Oxygen Generation
Used as a simple, safe, reliable and economical source of oxygen for both operational and emergency uses
Available as self contained or unit mounted variants
Minimum stowage space when compared with alternative oxygen sources
Long shelf life
No external power sources required

12. Critical Filtration
A variety of unwanted gases can be generated within a closed environment such as a submarine
These can include Carbon Monoxide, Hydrogen and other volatile organic compounds (VOC’s), which are hazardous to crew and equipment
Most common method of removal is a catalytic burner incorporating a bed of Hopcalite specially blended with Lithium Hydroxide
Catalytic oxidation can be high temp i.e Moleculite at 300°C, or low temp i.e. Sofnocat at 60°C

13. Carbon Monoxide Technology Hicap CO
High capacity CO removal
Rapid removal of CO over minutes
