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.”

Case study: Open aisle containment
The chillers give us 1500kW n + 1 cooling plus a stunning reduction in electricity consumption i.e.
2.5 times cooling capacity for 100 – 150kW less power consumption per day.
Mark Ford
Data Centre Manager
Case study: Hot aisle containment
Airedale provides us with a fully integrated cooling solution designed for maximum efficiency and
critical redundancy…Our carbon neutral status helps our clients take huge steps towards their own
environmental goals and carbon reduction commitments.
Rob Garbutt
Chief Executive Officer
Case study: InRakTM hot aisle containment
The InRakTM 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.
Mike Marchant
Data Centre Manager
Case study: OnRakTM compact hot aisle
Our HPC facility at Leeds is growing …by meeting our space constraints and slotting into our existing cooling loop, the OnRakTM units from Airedale have
saved us space in an already densely packed environment
