Immersion cooling

OCtoPus Tank

From 21 to 39 OpenU servers in a tank

Get to the highest level of cooling

To go deeper into energy-saving and performance, 2CRSI develops immersion cooling solutions.

Servers are submerged in tanks, then filled with a non-conductive fluid that cools all the components down, allowing them to reach the highest level of data center efficiency.

Thanks to immersion cooling, fans become useless and data centers no longer need to invest in expensive and inefficient air conditioning systems. At the scale of a data center, this represents 25% savings on the implementation of a datacenter (CAPEX) and 40% on its operating costs (OPEX).

Immersion cooling is a sustainable choice: the life of the components is extended, energy consumption is reduced and the heat generated can be reused.
