Maintain Media & Broadcast Equipment Uptime

Broadcast Equipment Corrosion Prevention: Protect Electronic Equipment for Media Broadcasting Rooms

Television has hooked millions with daily soap operas, live cricket matches, news, documentaries, and more. The varied TV channels have their own set of audiences 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 lives.

In the last three decades, the rapidly evolving people’s expectations have drastically gone up and so has 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 the high number of TV channels, people have expectations for continuous and quality transmission.

For consistent transmission and effective broadcast equipment corrosion prevention, broadcast engineers are put under pressure to maintain the equipment rooms in the broadcast facility such as the Central Apparatus Room (CAR) and production control rooms.

Equipment Rooms in the Broadcast Facility of the TV Channel

Equipment rooms are the heart of the TV channel. Each TV channel has several of these types of rooms which include:

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

Central apparatus room (CAR) has a critical function, it requires special care and a controlled environment to ensure broadcast equipment corrosion prevention. CAR houses common equipment that is 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 contaminated air i.e., corrosive gases which may lead to micro-corrosion and eventually, transmission breakdown. Corrosion may interfere with or interrupt the broadcasting signals.

The corrosive gases along with humidity and uncontrolled temperature can accelerate the chemical reaction and contribute to electronic corrosion in production control rooms, editing rooms, and newsrooms in the facility. It causes malfunction of equipment, making broadcast equipment corrosion prevention essential.

Although temperature can be controlled through normal air-conditioners, gaseous contamination control requires dedicated Gas Phase Filtration Systems. Neglecting even an extremely low level of corrosive gases can have costly and unforeseen ramifications.

Gas Phase Filtration System – The Most Effective Way of Broadcast Equipment Corrosion Prevention

Bry-Air Gas Phase Filtration Systems protect electronic equipment and devices from the threat of abrupt failures due to corrosive gases. It reduces downtime by removing corrosive gases through the process of adsorption and chemisorption. It is designed to maintain the ANSI/ISA-71.04-2013 standard, IEC standards and various other environmental standards followed by electronics manufacturers.

These GPF systems also neutralise odourous gases and make the environment comfortable for humans.

Bry-Air: A Step Ahead, Always

Bry-Air is the only Gas Phase Filtration Company in India having its own R&D and Testing Lab for granular media and chemical filters. Backed by world-class technology and systems, the laboratory is capable of testing the performance of impregnated/non-impregnated loose granular media and impregnated/non-impregnated air cleaning devices such as chemical filters, under one roof. The tests are conducted as per ISO/ASHRAE Standard 145.1 and BSR/ASHRAE Standard 145.2/ISO Standard 11155-2 guidelines. The core objectives of the tests are to assess the performance and efficiency of loose granular sorptive media and chemical filters in any particular application.

Frequently Asked Questions

What causes corrosion in broadcast and media equipment?

Corrosive gases such as H₂S, SO₂, NOx, Cl₂ and other reactive contaminants can enter controlled spaces through ventilation and fresh-air systems. These contaminants can react with metals and electronic components, affecting PCBs, connectors, contacts and other sensitive equipment.

Which broadcast facilities can benefit from gas phase filtration?

Gas phase filtration can be considered for broadcast control rooms, transmission rooms, equipment rooms, studios, technical rooms and other spaces housing sensitive electronic systems, particularly where outdoor or surrounding air may contain corrosive gaseous contaminants.

Can conventional HVAC or particulate filters prevent equipment corrosion?

Not by themselves. Conventional particulate filters are designed primarily to remove particles, while gas phase filtration uses adsorbent or chemically treated media to remove gaseous molecular contaminants.

How can corrosive gases reach a broadcast equipment room?

Contaminated outdoor air can enter through fresh-air intakes, HVAC systems, building leakage, door openings and other air paths. Once inside, gaseous contaminants can circulate around sensitive electronic equipment.

Which Bry-Air system is suitable for larger broadcast or media control rooms?

The EcoScrub™ Deep Bed System is designed for larger controlled spaces and DCS/control-room applications, with a 250–10,000 CFM capacity range. Its deep granular media bed provides extended gas–media contact time for gaseous contaminant removal.

Where would a Thin Vertical Bed System fit in a broadcast facility?

A Thin Vertical Bed System can be considered where space is limited and protection is required for smaller controlled areas such as equipment, relay or technical rooms. The system is designed as a compact, modular gas-phase filtration configuration with a 500–2,000 CFM capacity range.

Can gas phase filtration be integrated with an existing broadcast HVAC system?

Yes. DRISORB™ honeycomb panels are designed for integration into existing AHU/HVAC systems. Their structured media format provides a way to address gaseous contaminants without necessarily replacing the complete air-handling system.
