3. On-Site Gas Supply
What we Do
We provide a simple solution using cryogenic Argon in step with carefully designed delivery
systems.
Our specially selected ISO containers are placed on the project site where the liquid Argon can be
transferred into cylinders or smaller cryogenic vessels.
Our Impact
While the cost of Argon in overall project costs is often very small, the absence of Argon often
results in loss of production as the project comes to a standstill.
We were pleased to implement our full solution to a mine in the Katanga mining region in the DRC
where Argon availability improved from 30 % to 99.5% with our system.

4. Argon in Africa
Poor local infrastructure
• Poor Supply Reliability and Impurity of Gases
• High Costs associated with Supply
• No Local Manufacturing Capability or Capacity
Importing sometimes the only solution and Leads to:
• Shipping delays
• Clearing delays
• Cylinders need to be repatriated at a very high cost
• Hidden costs make Actual costs confusing
• Minimum order quantity 250 cylinders

6. What makes our Solution Unique
Focus on the minute details
• Choose the correct cryogenic equipment
- Only the best ISO tankers
• Carry out inter-trip maintenance
- Competitors only do annual or two yearly
• Follow unique filling procedure
- Personally supervised
- Load conditioning
- Filling ratios

7. Building the Supply Solution
Custom Tailored to Client Needs
• Each Cryogenic ISO tanker provides between 17-20 tonnes
• What is current cylinder population?
• What is monthly consumption?
• What would unconstrained monthly consumption be?
• What are Purity requirements?
• Designing and sizing Compressor and Manifold
Because Quality Matters

8. Proven Track Record
Systems installed in:
• Kenya
• Nigeria
• DRC
• Namibia
• Two existing systems in Namibia and DRC
• In all cases the costs have reduced and the reliability has improved
• Installation Copper Mine DRC - Operating 7 Years
