Waveguide & Cable Dehydrators
Dehydrators protect waveguides, feeds, radomes, and antenna assemblies by supplying dry, pressurized air. Maintaining a slight positive pressure (typically a few kPa) prevents moisture ingress and condensation, avoiding attenuation increase and VSWR degradation.
Depending on the application, systems use membrane or desiccant drying with oil-free micro-compressors. Modern units provide dew point monitoring, pressure control, SNMP/relay alarms, bypass/redundancy options, low-noise operation, and indoor/outdoor variants. Typical use cases include satellite earth stations, VSAT, microwave links, Ka/Ku/C/X-band feeds, and test benches.
