ETI General Information

• ETI is a privately owned corporation which was formed by Thad Jones in 1968. The company’s corporate headquarters and manufacturing facility is located at 1850 N. Sheridan Street in South Bend Indiana.

• For over 35 years, ETI has manufactured reliable specialty control equipment including a reliable line of dehydrators for waveguide and coaxial cable use as well as automatic controls, sensors, specialized cable and insulating covers used for Satellite Earth Station , Terrestrial Microwave and insulating covers used for Satellite Earth Station , Terrestrial Microwave and FM/ Broadcast antenna deice systems. ETI’s electric resistance heat deice systems have been installed on thousands of satellite antennas with apertures ranging from 50 centimeters – 10 meters. ETI supplies many sectors such as Government and Military, Utilities and Energy, Oil and Gas, Transportation and Highway, Railroad, Airport Authorities/Aviation, Fixed and Mobile Broadcast applications as well as many General Industrial and Commercial segments.

• ETI also designs and manufactures energy management controls for freeze protection and temperature management applications for Residential, Commercial and Industrial segments in multiple applications. Examples of these are roof and gutter deice, pavement deice and heat trace.

Why use a dehydrator?

In all transmission systems electromagnetic waves h ave to be transported from the amplifier to the rec eiver.The transmission path is divided into several parts.

amplifier - waveguide - antennaantenna - waveguide – receiver

• Electromagnetic waves can only be transported completely undistorted in an absolute vacuum and through absolute-reflecting guides. In practice, however, this is impossible. Obstacles in the form of dust particles and water molecules etc., as well as waveguide imperfections caused by corrosion will distort the electromagnetic. waves by scattering, velocity loss, time differentials, and so on.waves by scattering, velocity loss, time differentials, and so on.

• As wave guides, horn antennas and cables are never 100% air-tight, the best practical way of preventing solid particles and water vapor from entering the transmission components and causing corrosion, is to pressurize the transmission lines. In order to maintain a low relative humidity inside the transmission components under all conditions, the air has to be clean and very dry.

Dry pressurizing systems are used for pressurizing –• Waveguide in static installation• Horn antennas• Waveguides in mobile installations• Waveguides in radar installation• Radomes• Transmission Cables• Low noise amplifiers

Dehydrators and Accessories

ETI produces three types of dehydrators:• Passive • Manually Regenerated• Automatic Regenerating• Automatic Regenerating

02/21/2012 Page 5

Dehydrators - Passive

RCD 1 - No moving parts• Desiccant life - 12 to 18 months, or longer, before requiring

regeneration or replacement depending on conditions• Used to dry waveguide and coax in fixed, mobile and solar

powered systems with volumes up to one cubic foot. Also used for emergency situations w/out power

• Both systems use a blend of silica gel and activated alumina desiccants (regenerate in convection or conventional oven)desiccants (regenerate in convection or conventional oven)

RCD 2 - One moving part• The RCD–2 provides a 1/8" male fitting - For proper gas diffusion

to waveguide

• Uses ambient temperature variations for pressurization -• Negative System Pressure occurs as the temperature drops.

Ambient air is drawn in through the desiccant. Internal pressure increases with ambient temperature, closing the check valve and pressurizing the system.
