PADI Tec Trimix Blender
Blend helium-based gases with precision, manage complex systems, and produce trimix safely for technical diving operations
Duration
1 day
Max Depth
Not applicable (non-diving course)
Level
Technical Support / Gas Management
Overview
The PADI Tec Trimix Blender course expands on basic gas blending, training divers and professionals to safely produce helium-based breathing gases, including trimix.
This program focuses on advanced blending procedures, oxygen and helium handling, and the systems required to produce accurate gas mixtures for technical diving. Divers develop the ability to manage increased complexity, precision, and safety requirements associated with mixed gas production.
At N9BO℠, this course is positioned as a critical operational capability — moving beyond nitrox blending into full technical gas production with control and accountability.
