Submarine Manufacturing & Products Limited

We sell Sofnolime which is used in hyperbaric chambers for CO2 absorbtion.  This is usually contained inside a CO2 scrubber which draws air in through a fan through a steel cannister which contains the sofnolime.  As the air filters through the canister, the CO2 is filtered out meaning the air is cleaned for re-breathing.

Diving grade Sofnolime® absorbs carbon dioxide ensuring a breathable atmosphere is maintained. It is optimised for the removal of carbon dioxide from recirculated air/ nitrox/heliox in rebreathers and saturation dive systems.
• Commercial and leisure diving rebreathers
• Dive chamber / bell scrubbers / gas reclaim systems
• Dive gas conditioning units

• High intrinsic carbon dioxide capacity
• Available with white to violet ph change indicator
• Irregular shaped/sized granules for optimum packing
• High attrition resistance (low dust formation)

We offer the CD Grade Sofnolime which is a 2.0mm to 5.0mm extrudate with a D-shaped cross-section. The 797 Grade has a smaller particle size (1.0mm to 2.5mm) and has a triangular cross-section, which combine to give a higher CO2 absorption capacity.
