Laying Out the Insulated Panels at Aspetar Hospital, Doha
QRA International has a flagship product for the world since 2016. The athletic chamber is the 'secret weapon' for many national sports associations for the purposes of peak performance enhancement of their sprinters, court game players, middle and long distance runners especially in the leadup to a major regional, international or global event.
Many athletes have been using the environmental chamber low O2 regimen to condition their bodies to get maximal performance for up to 2 weeks after use.
Singapore's fine performance of its court, track, sailing, and high jump athletes post COVID is testament to the proper use of these top end equipment, together with a comprehensive coaching regimen, sleep and nutrition schedules which have made us a mini sporting nation.
QRA International has been fortunate to sell, install and commission 4 such chambers worldwide to the top National Sports Associations. They are :
1. Sports Singapore
2. Defence Organization Singapore
3. Aspetar Qatar Hospital
4. University of Canberra Sports Research Institute.
We are but one of 4 major brands worldwide producing such chambers for human and athlete use.

The chamber in a nutshell is just a controlled environmental room.
The limits of the controlled environment of the chamber is determined by the limits in which our world's environment. However, since there are no ultra marathons in -40 C in Kamchatka or Siberia, there is no need to control the temperature to -40 C. Most chambers which we design reach lows of 0C or -20 C. The control of -20 C means that the panels used for the chamber must be polyurethane filled for proper insulation, else 'sweating' of the exterior walls of the chamber will occur (say inside is -20 and outside is 30C) due to insufficient insulation resulting in condensation - which will be a major electrical shock risk.
The highest temperature reached is +50 C which can be reached in desert climates like the Sahara and Gobi deserts.
Temperature Range (Athletic Chamber) : 0 C to +50 C
Putting Up the Panels
Humidity levels are typically from 20% to 95% (Singapore's humidity is easily 70 - 80% most times of the year). The humidity in the chamber is controlled using steam generation (100%) and a cooling coil to reduce the RH by condensation. Rather overuse of power, but it generates the necessary humidity nonetheless.
Therefore Relative Humidity : 20 - 95%
For elite athletes and conditioned athletes to train inside the chamber, QRA employs the use of Amine scrubbers which typically 'catch' the CO2 molecules from the air passing through and 'cleaning' the air to be pumped back into the room by this method. Many modern day submarines employ scrubbers to filter out the CO2 and pump back the cleaned air into the cabin of the craft, ensuring that the submarine can stay underwater weeks or months on end.
Human beings emit a lot of CO2 out into the atmosphere and a surprising fact if that many people die in enclosed spaces due to Carbon Dioxide poisoning rather than Oxygen deprivation or too low levels of oxygen when they are trapped in an enclosed space (say a closed mine, or skiers in a crevice). So the enclosed air must be 'scrubbed' clean and recycled back into the enclosed room or chamber.
CO2 safe levels : less than 2000 parts per million per m3 of air.
