The 2nd Law of Thermodynamics
“The second law states that spontaneous natural processes increase entropy overall, or in another formulation that heat can spontaneously be conducted or radiated only
from a higher-temperature region to a lower-temperature region, but not the other way around.”

The InRak is perfectly designed…the units are very clever; they ‘talk’ to each other and maintain pressure
in the room. ACIS gives us 24/7 control of the operation and peace of mind.

35% savings vs. standard DX
Our HPC facility at Leeds is growing …by meeting our space constraints and slotting into our existing cooling loop, the OnRak units from Airedale have saved us space in an already densely packed
environment
