Case Studies > Plasma Cooling 
Overview 
A UK Plasma Power Specialist contacted TES with a requirement to use raw and deionised water to cool a mix of plasma torches and sub circuits. Power electronics were also to be cooled at lower temperatures. Each circuit was to be linked to a distribution manifold delivering metered raw and deionised water plus Nitrogen and Argon gas to multi circuit outlets.  
The whole system was to be installed in a cellar, the only access being via a service lift.  
 
The Solution 
The overall project was designed to have three cooling circuits all at different pressures. The electronics cooling system having a dedicated fail safe pressure circuit.  
 
The whole constructed upon a very strong base frame in four parts with easy to connect sections.  
 
Outcome 
The complete system was built and tested at TES. The cooling unit transported in four parts to South Korea. Here via the lift was re-assembled into single base allowing the system to be installed quickly without problems.

Technical Details 
The four section steel base supporting all three unique cooling systems.  
 
One delivering 91 lpm of pure water at 7 bar.  
One delivering 530 lpm of raw water at 6 bar.
