Ventilation Plugs or Pressure Balance Elements : The main function of these products is to balance the pressure between inside and outside of an enclosure.
The maximum temperature of an enclosure depends on the environmental conditions, power or heat dissipation of the electronic components inside the enclosure. Vent plugs or pressure balance elements helps to achieve a balance by reducing the temperature of the enclosure by improving the cooling of the enclosure.
It balances the pressure between the inside and outside of an enclosure and eases the strain on the enclosure seals and gaskets thus extending the life of the entire system.
They are provided with a special hydrophobic material membrane which allows passage of air and gases and blocks liquids and solids to enter inside the enclosure.
Available in Pg thread, Metric thread options in both Polyamide and Brass options.
Whether street lighting, railway vehicles or solar panels, all types of equipment must resist the effects of wind, weather, heat and rain. This applies to electronic and electrical enclosures also. Air pressure, temperature and humidity levels are constantly changing. Many electrical enclosures are sealed against the ingress of water and dust (IP68), but are not vapor tight. As a result of warming, from either the sun’s radiation or the enclosed electronics, pressure differences develop between the housing and its surrounding environment, which results in the transfer of air from one to the other. Air drawn into the housing carries moisture, which condenses when the temperature drops below the dew point. The water, which is now trapped in the enclosure, can lead to corrosion and equipment failures.
To prevent pressure differences, high humidity and condensation of water in the housing, constant balancing of pressure and exchange of air is needed. The use of pressure balance elements in electrical and electronic enclosures allows efficient pressure balance and ventilation.
It prevents the increase in pressure inside the enclosure.
Prevents increase in temperature inside the enclosure by air circulation.
Added flexibility for maintenance and increased life of gaskets and seals.
Prevents accidental suction of water into the system.
These Pressure Balance Elements or Ventilation Plugs provide:
Secure, reliable connections and seals
Highest level of protection against dirt, dust, corrosion, oil, grease, liquids, moisture, and gases
Reliable performance in high and low temperature environments
High level of reliability, durability and performance.
Electric and electronic enclosures, Street lighting and lighting producers, Railway, Automobile headlamp, solar panels, Control cabinets,
The Ventilation plug can reduce and can fully eliminate the adverse effects caused by humidity present in the environment which effect the life of the components inside the enclosures or equipment’s.
