ETi ADH NETCOM automatic Dehydrator

The ETi ADH NETCOM automatic Dehydrator supplies low pressure dry air to keep waveguide and coaxial cable dry. Output pressure is field 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.

The ADH NETCOM dehydrator is Ethernet network ready. Units can be configured and monitored using either built-in SNMP support or the web interface. Legacy system support is provided via RS-422/485 or RS-232 interfaces. Three programmable alarm relays are also included. User display shows output pressure, duty cycle, temperature, compressor hours and air-drying canister status.

The ETi ADH NETCOM automatic dehydrator uses a brushless dual-diaphragm pump for long life. Dehydrator operates with exceptionally low noise and vibration levels. The air-drying canisters use aluminum oxide desiccant for high efficiency. The humidity sensor signals for regeneration based upon current dew point rather than at fixed time intervals for additional energy savings and long desiccant life.

The ADH NETCOM dehydrator requires only 5-1/4″ (3-U) of rack space and is just 12.25″ (304.8mm) deep. Mounting hardware allows for flexible installation options including dual- and single-post rack mounting and wall mounting. The standard unit weighs just 16 lbs (7.26 kg). The ADH NETCOM automatic dehydrator operates from 100-240 VAC, 50/60 Hz. Optional units are also available at ±20-75 VDC. The dehydrator consumes a maximum of 150 watts during regeneration and about 40 watts otherwise. Heat dissipated is up to 512 BTU/hr during regeneration and about 136 BTU/hr otherwise. The ADH NETCOM creates an exceptionally low heat load for an automatic dehydrator.

A panel with display allows for IP configuration and status monitoring with or without network connection.
