ETI ADH NETCOM NEMA Outdoor Automatic Waveguide Dehydrator

ETI ADH NETCOM NEMA Outdoor Automatic Waveguide Dehydrator

The ETI ADH NETCOM NEMA is an outdoor automatic air dehydrator that supplies dry, pressurized air to protect antenna waveguides, dielectric coaxial cables and other pressurized systems in harsh, remote and high-vibration environments.

The dehydrator combines the monitoring and control capabilities of the standard ADH NETCOM with a durable IP66/NEMA 4X enclosure. It supports remote operation through an Ethernet web interface or SNMP, while RS-422/485, RS-232 and programmable alarm relays provide compatibility with legacy monitoring systems.

A brushless dual-diaphragm compressor and demand-based desiccant regeneration provide quiet, energy-efficient operation. The pressure range, alarm levels and master/slave configuration are field programmable. Mil-Spec connector configurations are also available for specialized installations.
