Oxygen Reduction System in a Data Centre

WHERE? Oxygen Reduction System, England

WHAT? A data centre is a facility that stores, manages and disseminates data.  Data centres are now supporting a variety of heavy industries such as mines.

WHY? Oxygen Reduction system works by taking Nitrogen from the air outdoors and pumping this into the room consistently in order to suppress oxygen levels, down to the level where combustion can no longer occur. To ensure the system works safely and efficiently, room integrity is of utmost important for two reasons: (1) A properly sealed room will contain the Nitrogen for a longer period of time, therefore putting less work on the air compressor in order to save energy. (2) If Nitrogen starts to leak from the Server Room, there are safety concerns over where this Nitrogen would leak to as it has the potential to harm occupants in other rooms if the Nitrogen leaks into their room and the oxygen levels were unmonitored.

HOW? Several areas were tested with an ultrasonic room integrity tester where leakage was probable and the readings were noted on the drawings. These were the doors, vents, cable penetrations and also sections of the wall where gaps were visible. The ultrasonic room integrity tester identified the main source of leaks for the room, the doors, where full readings were clearly detected. Multiple air vents in the room were also improperly sealed and some leakage was found into the external room. Cable penetrations leading to the area outside the Server Room were also found to be leaking. Once the required maintenance was conducted and assuming no changes were made to the room, it is safe to assume that the room retains its integrity, thus comply and exceed current ISO 14520 regulations requiring periodic inspections of room integrity whereby visual inspection is usually specified and is not sufficient.

WHAT? The most suitable way to address periodic inspections is through the use of ultrasound. The Portascanner® 520 uses ultrasonic technology to not only pinpoint precise leak locations, but to determine their leak apertures as small as 0.06mm with a tolerance of +/-0.02mm, making it by far the most accurate device for this function. Portascanner® 520 also provides interpretation of the fire resistance of the desired locations, labelling them either airtight or calculates the overall leakage of the room. The advantages of being able to accurately detect the exact leak locations and size are self-evident when considered alongside the resistance to collapse and transfer of excessive heat. In a case where there is too much leakage in a room, the Portascanner® 520 is an unrivalled ideal for the rapid and accurate identification of these sites so that they can be sealed. It is lightweight, fast and easy to use, allowing leak site detection to increase its operational efficiency and speed to a degree that has never been seen thus far in the Fire Industry.

 

CEO Message

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.

My kindest regards,
Carl
