GORE® Protective Vents for Telecommunication Systems - Applicatioin

Today’s telecommunication systems aim for reliable connectivity everywhere – requiring more equipment in remote locations, and greater exposure to extreme environmental conditions.

GORE Protective Vents can extend the service life of telecommunication equipment, reducing maintenance costs, warranty claims and customer frustrations, because they:

  • effectively manage pressure differentials within the equipment housing
  • prevent condensation from compromising sensitive electronics
  • reduce stress on housing seals
  • block ingress of rain, moisture, wind-borne particulates and other contaminants
  • eliminate the need for “ruggedized” housings, reducing costs and weight

Gore, the global leader in venting technology, has more than 15 years’ experience in developing custom venting solutions for the telecommunications industry. Our global R&D and engineering teams can partner with you from initial product concept through prototyping, sampling, testing and production integration.

Why Vent?
1

Electronic enclosures that are installed outdoors are vulnerable to a wide range of environmental hazards that can affect the performance, reliability and life expectancy of the sensitive electronics within.

Paragraphs
Enclosure seal

Pressure differentials are created when a sealed enclosure is exposed to rapid, extreme or recurring changes in ambient conditions. Extreme changes in temperature (a sudden thunderstorm on a hot, sunny day), altitude changes (in transit), or the constant heating and cooling cycle of an internal heat source – any of these can cause a pressure differential within a sealed enclosure. A rapid decrease in temperature, for example, can create a vacuum inside the enclosure. If this pressure differential is not dissipated, the vacuum places continual stress on the housing seals. Over time, this can cause seals to fail, allowing moisture and other contaminants such as dust, dirt and other particulates to be drawn inside.

Failed Seals

Paragraphs
Cloudy pane due to condensation

In addition to failed seals, moisture can get inside enclosures by diffusion – the process by which vapor moves by natural molecular motion through the walls of a polymer enclosure. When water vapor enters a sealed enclosure and has no way to escape, it will condense to a liquid state. If this condensation remains inside the sealed enclosure, it can compromise lens function and corrode sensitive electronics and battery contacts.

Equalize Pressures to Protect Housing Enclosures and Seals
GORE Protective Vents equalize pressure by enabling air to pass through the ePTFE membrane

GORE Protective Vents rapidly equalize pressure differentials within sealed enclosures, effectively preventing the internal vacuums or pressure build-ups that stress housing seals. In non-vented housings, pressure differentials as low as 70 mbar (1 psi) can cause seals to leak after repeated temperature cycles. GORE Vents reliably protect against premature seal failure, to preserve the integrity of the enclosure.

Prevent Contamination to Protect Electronics
GORE Protective Vents prevent contamination because they effectively block ingress of liquids and particulates

GORE Protective Vents reliably block ingress of a wide range of contaminants, from rain and insects to dirt, dust, sand and other particulates. Yet GORE Vents allow air molecules to pass through, preventing the formation of vacuums that could pull external contaminants in. With vents from Gore, components perform reliably, with lower maintenance or warranty costs.

Reduce Condensation to Protect Against Corrosion
GORE Protective Vents reduce condensation by allowing water vapor molecules to exit through the ePTFE membrane

GORE Protective Vents enable water vapor molecules to diffuse through the microporous membrane, and pass freely out of the enclosure. By reducing the amount of internal moisture, internal surfaces such as lenses are protected from condensation, and electronics are protected from premature failure due to corrosion.

Protect Against Hazardous Gas Buildup
GORE Protective Vents reduce explosion hazards by effectively dissipating hazardous gas molecules.

During normal operation and recharging cycles, batteries can generate heat and emit hydrogen or other gases. This can create a hazardous, or even explosive, situation. GORE Protective Vents effectively dissipate hazardous gas molecules. By continuously equalizing pressures inside and outside the battery compartment, they reduce explosion hazards, while maintaining an effective barrier to liquids and particulates.

Tower-Top Electronic Enclosures
Tower-Top Electronic Enclosures Water can cause corrosion and shorts to the electronics in tower-top enclosures. By allowing moisture vapor to diffuse easily, GORE Protective Vents reduce potential condensation that leads to corrosion and shorts.
Base Station Battery Units
Base Station Battery Units To prevent potential explosions, hydrogen gases from batteries must have an exit path. The continuous airflow of GORE Protective Vents enables gases to flow out of the unit while creating a barrier against contaminants.
Small Cell Nodes
Small Cell Nodes Plastic housings commonly used in small cell nodes are more susceptible to pressure equalization issues. Gore’s venting solutions protect the electronics from water damage and comply with environmental standards.
Antenna Tilt Motors
Antenna Tilt Motors Mechanical components of the antenna motors can fail when exposed to liquids and other contaminants. GORE Protective Vents provide a barrier against liquid and other contaminants that can lead to corrosion.
Coverage Systems
Coverage Systems Water ingress can compromise the signal integrity of coverage devices like repeaters and backhaul devices, including point-to-point and microwave radios. By equalizing pressure inside the device housing, GORE Protective Vents prevent stress on the housing seals so water cannot enter.
Tower-Mounted Sensors
Tower-Mounted Sensors Rapid temperature changes create a vacuum inside the sensor, which can cause a seal to fail. Moisture vapor can enter and condense on the sensor dome, obstructing sunlight and compromising sensor measurements. GORE Protective Vents equalize pressure and prevent vacuums that compromise seal integrity.
