ETI EDH-5 Indoor/Outdoor Low-Pressure Waveguide Dehydrator

ETI EDH-5 Indoor/Outdoor Low-Pressure Waveguide Dehydrator

The ETI NETCOM EDH-5 is a compact, low-pressure air dehydrator designed to supply clean, dry air to small-volume antenna waveguides and coaxial-cable systems in indoor, outdoor, remote and mobile installations.

Well suited for Ku- and Ka-band applications, the EDH-5 provides an output pressure of 0.3-0.5 psig with a maximum flow rate of 4.77 scfh (2.25 lpm). Its microcontroller regulates pressure and manages dehydrator functions, while solid-state controls help ensure reliable operation.

A two-digit LED display provides pressure, internal temperature, flow rate, operating status, duty cycle and error-code information. The single desiccant container is accessible from the front for convenient replacement or manual regeneration. Continuous pump operation is limited to four hours to protect the dehydrator if a severe system leak occurs.
