Why become a DSAT Gas Blender for Nitrox or Trimix Blending?

It's a way to get the necessary knowledge to safely mix enriched air or to learn about the various hardware options available and the pros and cons of each. DSAT has just released a Gas Blender course, and even if you are not certain yet that you want to invest in an enriched air blending system it will pay you to attend this course. The knowledge you will gain will help you to make an informed choice as to whether this is logical direction for your business, and, if so, what your requirements would be.

The course takes you step-by-step through the essential information needed to mix diving gases, including helium mixes such as trimix, in a safe and accurate way. Concepts are introduced in an easy-to-follow manual and illustrated with instructor lesson guides. The importance of handling oxygen correctly is dealt with extensively, including why high-pressure oxygen can cause fires or explosion if handled improperly. You are shown what types of materials are compatible with oxygen and why some kinds of 'standard' materials must be avoided (eg silicone grease).

The type of oxygen you can use, the quality of air needed to mix with it, and the various mixing systems are all covered, including partial pressure mixing, continuous flow, pressure swing absorption and differential permeability. These represent some of the practical options you might use for filling a cylinder, from the simplest case where you just add some oxygen and top up with air, to a sophisticated, high-output system.

Best of all, you do not need to use a lot of complicated formulas to work out the amount of gases to add to make a mix. That's where the Gas Mix Calculator (software) comes in... Three coloured sliders allow you to enter what amounts of oxygen, nitrogen and (if applicable) helium are already in the cylinder to be filled, and three more sliders allow you to dial in what you want. The programme instantly tells you how much oxygen, nitrogen or helium you must add to get the target mix.

The DSAT Gas Blender course not only increases your professional qualifications, it also covers a fascinating subject in an easy-to-follow, uncomplicated way.

What will I need and how long is the course?

PADI Enriched Air Diver certification (or qualifying certification from another organization) Minimum age: 18 years old and DSAT Gas Blender Manual Gas Mix Calculator (need a week before the start of the Course to complete all Knowledge Reviews etc) Will be done over 1 day (half in classroom and half in dive centre/compressor room)

Calendar shows where I will be and duration of my time there. If I am in your area and you want to join a course, contact me for locations. If you see any dates free and would like me to visit your dive centre or location, drop me an email with location, course interest and possible dates.
Want to know more about how your cylinders weight changes during a dive..? Video has information on what effects the weight change and has tests showing cylinders at different air pressures during dives in salt and fresh water. It displays whether they have Negative, Neutral or Positive Buoyancy. More details found at www.sidemountscubadiving.com
