Server Rooms / IT Rooms

The problem of Air Pollution and Contamination in Server Rooms

IT & electronic equipment’s reliability and availability is critical for smooth operation of IT enabled services/ KPOs, BPOs, Telecom, News and Media, Data centers, Semi-conductors, Distributed Control System (DCS), Switch Rooms and Motor Control Centers of Pulp & Paper, Refinery, Chemical, Fertilizers and Petrochemical units.

Unwanted Airborne Contaminants disrupt the  functioning of electronic equipment

Contaminants internal as well as external are largely responsible  for huge losses in the IT enabled industry. These seep into data processing facilities  and corrode electronic equipment leading to malfunction and breakdown of computers, telcom systems, ACs, control panels etc.

Internal Contaminants

Contaminants are generally generated indoors in Data Processing and Computer Printing Facilities. These facilities are equipped with high quality air filtration equipment to arrest very fine airborne particles generated from high speed printers. If these are not removed then they deposit on the surface of disc drives and electronic circuits and can create maintenance downtime.

Similarly gaseous contaminants released form machines using chemicals and toners corrode the delicate electronic circuitry of the computer, disc drive and printers:

Contaminant Contamination level
Ammonia 1.4-1.6
Chlorine .004~.006
Nitrogen Dioxide .002~.003
Ozone 0.1~0.3
VOCs (as Toulene) .01~.02

External Contaminants

Offices are more prone to air pollution from gaseous airborne contamination if it is situated near :

  • Sewerage / drains
  • Landfill sites
  • High density traffic
  • Process Industry (emanating industrial effluents)

Gaseous contaminants and other sources of  air pollution such as  Hydrogen Sulphide (H2S), Sulphur Dioxide (SO2), Bromine and Oxides of Nitrogen, Chlorine etc., seep into the conditioned space of modern plush offices. These gases alone or in combination with humidity and/or with temperature reacts with copper and silver in electronic circuit boards, server cards, EVA, cooling equipments, datacom connections resulting in micro – electronic corrosion/malfunction resulting in downtime losses. Downtime which translates into data loss, revenue loss and ultimately customer dissatisfaction.

Why do we need to protect our server and computer rooms?

Studies have shown that atmospheres which produce corrosion rates greater than 0.1 microns per year cause unacceptable number of corrosion -related failures of micro-circuitry.

Corrosion rate per year vs equipment failure

<0.1 micron no failure found
>0.1 micron intermittent failures in 1-2 years
>0.4 micron inoperative in 2-4 years
>0.6 micron intermittent failures in .5-1year
> 2 micron inoperative in 0.25 -.5 years.
  • For electronic equipment,corrosion rate has to be below 0.1 micron per year.
  • For electrical equipment, the same can be as high as 0.5 micron per year.

Gaseous Filteration the most effective way of removing airborne contaminants

Protecting the datacom equipments and servers from any potential contaminants threat is a vital step in ensuring your datacom equipments and servers good health and continued viability. The ultimate solution to corrosion lies in gaseous filtration, which involves passing the contaminant laden air stream through a bed of dry media placed in a properly designed housing.

Bry-Air EcoScrub is ideal for human and hardware health

It removes contaminants and other sources of air pollution and thus eliminates downtime by removing corrosive gases through the process of adsorption and chemisorption. The principle of air filtration is simple: the contaminated air passes through pre-filters which retain dust and particles. The chemical media stages (combination of activated carbon and activated alumina impregnated with proprietary chemicals) then chemically destroy remaining gaseous contaminants. Bry-Air EcoScrub is designed to maintain the ISA standard 71.04, IEC standard and Environmental standard 71.04, IEC standard and Environmental Standards followed by electronics manufacturers.

Bry-Air Moisture Solution

Bry-Air Dehumidifiers simplifies the environmental control problem by taking care of the moisture load independent of refrigeration equipment, and simple air conditioning equipment takes care of temperature control. The air conditioner and dehumidifier control temperature and humidity independently.
