Diving Gases

Certified breathing gas mixtures for recreational, technical and professional diving

Safety and Performance

Trimix (Oxygen, Helium, Nitrogen)

Ideal for deep dives beyond 40 meters. Thanks to helium, nitrogen content is reduced to avoid narcosis, and breathing stays comfortable and light. Perfect for technical divers and extreme dives.

We offer the following Trimix blends:

TRIMIX-18/45-EN 12021 50L (18%O2, 45%He/N2) TRIMIX-15/55-EN 12021 50L (15%O2, 55%He/N2) Supplied in 50-liter steel cylinders

Heliox (Helium, Oxygen)

The ideal blend for very deep dives, where nitrogen is completely eliminated (for example, for underwater work or specific technical challenges). Heliox offers maximum safety and reduces risks during deep dives.

We offer the following Heliox blends:

HELIOX-23/77-EN 12021 50L (23%O2/He)
HELIOX-18/82-EN 12021 50L (18%O2/He)
Supplied in 50-liter steel cylinders

Nitrox (Oxygen, Nitrogen)

The ideal gas blend for recreational divers wanting to extend their dives at moderate depths up to about 30 meters. A higher oxygen content reduces nitrogen absorption and increases your no-decompression time. Lower decompression risks for more comfort and safety.

We offer the following Nitrox blend:

NITROX-32-EN 12021 50L (32%O2/N2)

Supplied in 50-liter steel cylinders
