CTS designs and manufactures Type 4 carbon fiber diving cylinders specifically engineered for technical and professional underwater applications
Key Features of our Diving Cylinders
Thanks to their advanced multilayer composite design, CTS diving cylinders offer:
- Greater comfort and mobility underwater: Their lightweight structure allows divers to distribute weight more evenly across the body, rather than concentrating it all on the back. This leads to improved balance and a customizable swimming position for better efficiency and comfort.
- Versatility beyond the dive: Once out of the water and additional weights are removed, the diver is left with a lightweight and highly manageable SCBA system. This system can also be used in CBRN (Chemical, Biological, Radiological, and Nuclear) scenarios, firefighting, or any emergency that requires respiratory protection.
All CTS carbon fiber cylinders are built to withstand high working pressures and rigorously tested in compliance with the most stringent international standards, including EN 12245 and ISO 11119-3. They are PED and/or DOT certified, ensuring maximum safety and reliability in any situation.
Designed for universal compatibility, CTS diving cylinders feature valve threads that conform to international standards, ensuring seamless integration with most equipment used worldwide.
