Who is Submer?

Submer is a global leader in datacenter liquid cooling solutions, driving the transition toward more sustainable and energy-efficient digital infrastructure. Guided by its mission to create “Datacenters That Make Sense,” Submer develops innovative immersion cooling technologies that enable high-performance computing (HPC), hyperscale datacenters, edge computing, artificial intelligence (AI), and blockchain applications to operate more efficiently and sustainably. Since its founding in 2015, Submer has established itself as a trusted partner for some of the world's most advanced datacenter operators. Headquartered in Barcelona, Spain, the company also operates a Gigafactory in Houston, Texas, supporting its global growth and customer base.

QLOE and Submer are partners in the immersion cooling technology ecosystem since 2024. The partnership is the result of system-level validation process during which the QLOE coolant was exposed to power levels up to 225 kW using Hypertec immersion-born servers deployed in a Submer EXO SmartPod.
