Television has hooked millions with daily soap operas, live cricket matches, news, documentaries, and more. The varied TV channels have their own set of the audience like music and lifestyle for youth, food channels for chefs and foodies, cartoon channels for toddlers, and so on. The infotainment value has made TV an essential part of people’s everyday life.

In the last three decades, the rapidly evolving people’s expectations have drastically gone up and so as the number of broadcasting TV channels. Till 1991, there was only one TV channel in India, and today, we have over 900 TV channels available in India. Despite more number of TV channels, people have expectations for continuous and quality communication.

For consistent transmission, the broadcast engineers are put under pressure for maintaining the broadcast rooms such as Central Apparatus Room (CAR) and production control rooms. They are the hear of the TV channel. Each TV channels have several of these types of rooms.

Equipment rooms in the broadcast facility of the TV channel are

  • Central apparatus room (CAR)
  • Central machine room, or central equipment room (CER)
  • Central technical area (CTA), or rack room
  • Production control room or studio control room (SCR)
  • Broadcast control room

With CAR as a critical function, it requires special care and a controlled environment. CAR houses common equipment that are necessary to broadcast including

  • Amplifiers
  • Switches
  • Encoders
  • Video Servers
  • Transmitters
  • Modulators

The environment of the CAR plays a crucial role in the maintenance of all common equipment which is necessary for continuous transmission. The frequent door openings and ventilators may bring the contaminated air i.e. corrosive gasses inside the CAR, which may lead to micro-corrosion and eventually, transmission breakdown. Corrosion may interfere or interrupt the broadcasting signals.

The uncontrolled parameters like temperature, humidity can lead to:

  • Condensation
  • Electronic corrosion
  • Malfunction of equipment

The corrosive gasses along with humidity and uncontrolled temperature can accelerate the chemical reaction and contribute to electronic corrosion in production control rooms, editing rooms, and news rooms in facility. Although, temperature can be controlled through normal air-conditioners, but gaseous contamination control requires dedicated Gas Phase Filtration Systems. Neglecting even a extremely low level of corrosive gases can have costly and unforeseen ramifications. Bry-Air Gas Phase Systems removes contaminants and eliminates downtime by removing corrosive gases through the process of chemisorption using granular chemical media and gas phase filtration cassettes.
