What are the savings of a ColdLogik Rear Door Cooler ‘RDC’ data centre design, in comparison to a CRAC/H based system?

Up to 93% has been achieved over older CRAC/H based designs.  This is possible because an RDC design data centre is far more energy efficient, using less power to achieve the same level of cooling; furthermore, an RDC design operates at higher supply water temperatures and can therefore utilise ambient free cooling.
