Telecommunication towers are actually a part of Base Transceiver Station (BTS) which facilitates wireless communication between user equipment (mobile phones, handsets, WLL phones, computers with wireless internet connectivity) and a telecommunication network.
A BTS is controlled by a Base Station Controller (BSC). Generally, there are 3-4 BTS under each BSC site. BSC site is in turn connected to large centralized Mobile Switching Center (MSC) Site. A MSC is the center piece of a Network Switching Subsystem (NSS).
Base Transceiver Station (BTS) Components
A Base Transceiver Station has several sophisticated electronic devices. Each of the devices has an important task or utility for proper functioning of the BTS. It has equipment for encrypting and decrypting communications, spectrum filtering and several transceivers (TRXs) which allows it to serve different frequencies and different sectors of the cellular network. Antenna is just another component of BTS, facilitating proper functioning of BTS.
Considering the importance of each electronic component of BTS, BSC & MSC, together with high replacement costs associated with them, the need for their proper protection against airborne molecular contaminants cannot be over stressed.
BTS Locations and Risk of Component Damage due to Corrosion
The base transceiver stations which are located near industrial areas or places within the city where heavy traffic congestion is observed are exposed to the risk of corrosion of their sophisticated electronic components.
Atmospheric air, especially in industrial areas, is laden with molecules of corrosive gases like Hydrogen Sulphide (H2S), Sulphur Dioxide (SO2), Chlorine (Cl), Ammonia (NH3), Ozone (O3), Hydrogen Fluoride (HF), etc. which are generated during the manufacturing processes and eventually mix with the surrounding air.
Similar is the case of air within the city, where heavy traffic congestion can lead to high level of pollution along with dust particles suspended in the atmosphere. Airborne molecules of corrosive gases contaminate the air inside BTS Shelter and MSC Sites, which can damage the circuit boards of electronic devices installed there, reducing the life expectancy of these sophisticated devices apart from causing electronic malfunctions, signal failure and down time losses.
Corrosion of metals is caused primarily due to uncontrolled temperature and humidity inside the BTS Shelter and Mobile Switching Center. However, corrosion is aggravated by the attack of gaseous contaminants.
While measures are in place for controlling temperature and humidity, gaseous contamination is generally overlooked. To ensure proper protection against corrosion of electronic devices, gaseous contamination should also be controlled.
Bry-Air Atmospheric Corrosion Meter
To ensure proper protection of your electronic equipment you must start by measuring the level of contamination your devices are exposed to. Since Base Transceiver Stations BTS are located across the city, the level of contamination present in atmosphere will be different at each location. Bry-Air Atmospheric Corrosion Meter helps you gauge the level of protection required to keep your electronic devices safe from corrosion.
Bry-Air Gas Phase Filtration Systems
Bry-Air Gas Phase Filtration Systems helps you protect your electronics and telecommunication devices from corrosion and abrupt failures. It purifies the air inside the Base Transceiver Station shelter from corrosive contaminant gas molecules through the process of adsorption and chemisorption, in which contaminants are neutralized while passing through a chemical filter. The cleaning of contaminated air occurs at molecular level when a pollutant gas molecule reacts with the chemical present in the filter.
Bry-Air Gas Phase Filtration Systems are designed to remove contaminant gas up to acceptable level.
Bry-Air offers various types of air purification systems depending upon the method of purification and known parameters related to airflow, types and concentrations of impurities present in air, space availability and desired media life.
Bry-Air Honeycomb Chemical Filters - HCF Series
Bry-Air’s revolutionary macro porus honeycomb matrix technology based chemical filter facilitates highly efficient chemisorption process by holding maximum possible amount of chemical media for filtration process for a given size and geometry of the filter and has maximum air carrying capacity for a given pressure drop. It can neutralize even ultra low concentration of gaseous contamination in the air stream.
Bry-Air Honeycomb Chemical Filters are UL certified for highest standard of safety and quality.
BrySorbTM and DriSorbTM - Chemical Media
Bry-Air has a wide range of proprietary chemical media for removing gas phase contamination. BrySorb offers a wide range of combination of Activated Carbon and Activated Alumina impregnated with proprietary chemicals which destroy any gaseous contaminant like Thiol, Formaldehyde, Ammonia (NH3), Hydrogen Sulphide (H2S), and Methane (CH4).
The chemical in the filter gets consumed over time as it reacts with corrosive gases. Therefore, it needs to be replaced. Determining the time of replacement is important so that media is not replaced when its life is not over or we keep on using the media even after the chemical has been consumed. Bry-Air has in-house lab to facilitate media check at regular intervals. Just send us the sample of the chemical media and we will let you know the life of the chemical.
