Dehydrator - Pressurizer

Pressurisateur, Déhydrateur pour SatCom, Télécoms

SELECOM offers dehydration and pressurization equipment for wave guides, coaxial cables and UH heads

Indeed, in order to preserve moisture, HF transmission lines (wwaveguide, coaxial aerial….) supplied by high-power transmitters (several kW) ;, it is necessary to pressurize and dry these lines in order to avoid the ionization of the water molecules and to avoid  any risk of electric arc phenomena which have alle the chances of destroying the transmission line or even of provoking fire.


The pressurizer is intended to inject dry air into any HF system. The moisture content of the dried air is kept low enough to prevent condensation. This lowering of the dew point considerably increases the reliability and longevity of the system.
