Waterless Data Center Solutions

Best-in-Class Cooling with No Water in the White Space

Accelsius has partnered with OptiCool® Technologies to deliver innovative waterless liquid cooling systems for data centers.

The result is a comprehensive 2-Phase, Direct-to-Chip (DTC) cooling system coupled with active rear-door heat extraction (RDHx) to mitigate concerns about liquid cooling — with no chance of damaging leaks.
