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

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)

Oxygen Generators

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

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
