TDI GAS BLENDER SUITE
TDI Gas Blender Suite
Confidence, safety, and precision in every blend.
TDI Gas Blender Suite is structured around three separate certifications: Nitrox Gas Blender, Advanced Gas Blender, and O2 Service Technician. The eLearning is delivered as a single, unified program that incorporates the full theoretical content of all three courses. This approach eliminates redundancy and allows for a more efficient, progressive learning experience. Complete the theory once and apply it across multiple certification levels.
TDI Nitrox Gas Blender
Master the essential skills of enriched air blending and take control of a critical part of modern diving. Learn to safely handle oxygen, analyze mixtures, and produce consistent nitrox fills with precision and confidence. This course builds a strong foundation for safe, reliable gas blending in real-world environments. Explore this course
TDI Advanced Gas Blender
Take your skills further and step into advanced gas mixing. Learn to handle helium and create complex blends such as trimix with accuracy and control. This course prepares you to plan, execute, and verify precise mixes while maintaining the highest safety standards in technical diving environments. Explore this course
TDI O2 Service Technician
Go beyond blending and learn to prepare equipment for oxygen service with confidence. Focus on inspection, cleaning, and safe handling in high-oxygen environments. This course gives you the knowledge to manage contamination risks and support safe diving operations behind the scenes. Explore this course

Step One:
TDI Nitrox Gas Blender
Take Control of Every Fill. Master Nitrox Gas Blending.
What happens behind the fill station matters just as much as what happens underwater. This course puts you in control of one of the most critical parts of modern diving: creating safe, accurate nitrox blends. Learn how to handle oxygen, apply precise blending techniques, and deliver consistent results every time. Whether you’re working in a dive center or expanding your technical skillset, this is where real responsibility begins.
Master Nitrox Blending Systems
Understand and apply the most common nitrox production methods, including continuous blending, partial pressure blending, and banked gas systems. Learn when to use each method, how they work, and how to produce reliable mixes under real operational conditions.
Blend with Accuracy and Confidence
Control fill rates, manage heat buildup, and apply proven formulas to hit target mixes every time. You’ll learn how pressure, temperature, and gas behavior interact, so you can avoid costly mistakes and deliver consistent, accurate results.
Reduce Risk. Increase Responsibility.
Work safely with high-pressure oxygen systems, understand fire risks, and follow procedures that protect you, your team, and your customers. From proper documentation to gas analysis and certification verification, you’ll learn what it takes to operate professionally and responsibly.
Step Two:
TDI Oxygen Service Technician
Take Control of Oxygen Equipment Safety
Working with oxygen is one of the most critical responsibilities in diving operations. This course teaches you how to properly clean, prepare, and maintain equipment for high oxygen exposure. Learn the procedures, materials, and standards required to reduce risk, prevent contamination, and ensure every component is ready for safe use.
Oxygen Cleaning and Equipment Preparation
Learn how to properly clean cylinders, valves, and components to oxygen service standards, removing contaminants that can cause serious hazards.
Component Compatibility and Materials
Understand which materials, lubricants, and parts are safe for oxygen use and how to identify and replace incompatible components.
Safe Procedures and Risk Control
Apply proven procedures to reduce fire risk, control contamination, and maintain safe working environments when handling oxygen systems.
Step Three:
TDI Advanced Gas Blender
Take Your Blending Skills to the Next Level
Advanced gas blending takes everything you know about nitrox and pushes it further. Learn how to work with helium, create complex trimix blends, and manage the precision required for deep diving operations. This course builds the skills, control, and confidence needed to produce accurate mixes where there is no room for error.
Blend with Helium
and Trimix
Learn how to safely incorporate helium into your mixes and produce trimix for deeper diving applications. Understand how each gas behaves and how to control the final result with accuracy.
Precision Blending for Complex Mixes
Master the calculations and techniques required to blend multi gas mixtures. Small mistakes matter more at this level, and you will learn how to plan, execute, and verify every step.
Control Risk in Advanced Operations
Work with hypoxic gases, manage labeling and verification, and understand the risks involved in advanced blending. Build the discipline required for high level fill station operations.
