Product details
The ETI ADH NetCom is an automatic, regenerating air dehydrator that keeps antenna waveguide and dielectric coaxial cable filled with dry, pressurized air so moisture never degrades the signal. A brushless dual-diaphragm compressor feeds aluminum-oxide desiccant canisters that regenerate on measured dew point rather than a fixed timer, saving energy and desiccant. Output pressure is programmable from 0.3 to 7.5 psig, and the unit is monitored and controlled over Ethernet with a web interface or SNMP, with RS-422/485, RS-232 and three alarm relays for legacy systems. It fits 3U of rack space (or mounts on a wall), runs from 100-240 VAC or optional ±20-75 VDC, and supports master/slave operation for parallel or redundant pumping.

Frequently asked questions
Why do satellite antenna waveguides need a dehydrator?
Moisture that condenses inside waveguide and coax raises loss and VSWR, corrodes the line and can arc at high power. A dehydrator keeps the line filled with dry air at a slight positive pressure so moist air cannot leak in; Digisat can size the dehydrator and manifold to your waveguide runs and antennas.
Does Digisat supply ETI dehydrators and Snow Switch controls?
Yes. Digisat supplies ETI NetCom waveguide dehydrators, manifolds and Snow Switch de-icing controls and sensors with quote-based pricing, and our engineers can size and install them with your antennas and RF chain.
