THALES BROADCAST & MULTIMEDIA

Pure Water Cooling System

•Requires Constant Filtration

•Requires Constant Conductivity Monitoring

> Can take the HPA Off The Air

•Components must be made from:

> Stainless Steel

> Plastic Based

•Requires the use of “hose loops” for electrical isolation

•

•Does not insulate outside the vacuum envelope

•

•Requires external collector RF shielding
