Environmental Technology ETI ADH Netcom NEMA Outdoor Waveguide Air Dehydrator
Fully weatherized enclosure, light-weight with multiple antenna mounting options makes installation easy, Low energy use minimizes operational costs
ETI ADH Netcom Outdoor NEMA Enclosure Waveguide Air Dehydrator
The Environmental Technologies Inc. ETI ADH Netcom Dehydrator provides dry pressurized air to ensure the signal quality of antenna waveguide systems and dielectric coaxial cable performs in accordance with specifications. This Highly configurable outdoor air dehydrator meets the needs of a wide range of applications and is field programmable with operating pressure ranges from 0.10 psig to 7.50 psig (7mbar to 517mbar). Its brushless dual-diaphragm compressor provides a long life cycle and future-proof software based features allow updates and upgrades while in service.

Weatherproof
The ADH NETCOM NEMA automatic dehydrator provides the same functionality as a standard ADH NETCOM in an environmentally sheltered IP66, NEMA 4X enclosure. It is ideal for use with mobile satellite antenna installations and for outdoor mounting for pressurization systems localized to the antenna pedestal. This outdoor configuration is also ideal for use in pressurization systems in remote locations such as along rail lines, pipe lines and at power distribution substations. While the NEMA enclosure keeps out moisture, the temperature control system allows operation down to –40°F (–40°C) The ADH NETCOM NEMA automatic dehydrator weighs just 24 lbs (10.9 kg).
Efficient
The ADH NETCOM automatic outdoor 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.
An optional front panel with display allows for IP configuration and status monitoring when no network is available.
