Waveguide Automatic Air Dehydrator with Ethernet Communications

The ADH NETCOM automatic waveguide dehydrator supplies low pressure dry air to keep waveguide and coaxial cable dry. Output pressure is configurable between 0.10 psig and 7.50 psig (7mbar – 517mbar) in 0.01 psig (0.67mbar) increments. Factory default pressure is 0.5 psig (34.5mbar). Operational monitoring and alarms are software based making them highly configurable in the field. Future software features can be installed while in service over the internet or local Ethernet network. Tested and complies with many Military Standard specifications around the world.
