Submer is an idea born in 2015 from two brilliant and original minds, Daniel Pope and Pol Valls, to make operating and constructing data centers more sustainable and efficient. That idea still remains to this day, as the main driver of the Company:
"We enable next-generation cooling and automation for data & energy-intense environments by integrating our pristine, highly-efficient & sustainable technologies. Solving the challenges of today and powering the use cases of the future."
Submer helps enable datacenters that make sense through products, platforms, APIs, processes, and installations that will move hyperscalers, colocation, and huge industries to new levels of efficiency and innovation.

2. Deployment Requirements

Whether you plan to deploy Submer’s solutions in a completely new building or in an already existing facility, there are some basic requirements you need to keep in mind. These conditions are necessary for Submer’s solutions to work properly and safely and guarantee you unrivaled performance.

3. The benefits of working with Submer

Submer offers a series of modular, easily scalable solutions to help data centers and supercomputers be as efficient as possible and sustainable. By deploying Submer’s solutions, you’ll boost the performance of your datacenter, lower maintenance, and operational costs, and help the industry being smarter and greener

Getting a PUE <1.03

Saving 25%-40% on TCO

Achieving up to 100kW

Reducing latency and increasing speed deployment

Increasing HW life-span (+30%)

Achieving -60% in HW failure rate

Saving 50% on CAPEX building costs

Saving 95% on cooling OPEX

Deploying a “zero waste of water” technology

Allowing for re-use of the heat dissipated for other purposes

3.1 Save on TCO, CAPEX and OPEX

Submer allows saving 25%-40% on Total Cost of Ownership (TCO). In a traditional air-cooled HPC cluster, the TCO corresponds to about $407 million in a 5-year period, considering the complete lifecycle. An HPC cooled with Submer’s Immersion Cooling would have a TCO of $333 millions


This translates into substantial savings on CAPEX (Design, Real-Estate, Construction, IT hardware, Cables, Cooling, Piping, etc.)  and on OPEX (Electricity, Maintenance), creating the conditions for a Return on Investment (ROI) < 1 year. 

Working with Submer, means:

4. Submer: Changing the world, one datacenter at a time

In 2015, a team of industry forward-thinkers and innovation visionaries felt that it was time for the data center industry to turn over a new leaf. The idea was to challenge the way data centers are perceived and understood today and how this can create deep change in the way technology and humans behave.

Submer (https://submer.com) was born to pave the way towards next-generation datacenters. We design, build and install solutions for HPC, hyper-scale, datacenters, Edge, AI, DL, and blockchain applications. The SmartPodX advanced Immersion Cooling technology is the most practical, resilient, and eco-friendly LIC solution guaranteeing fast and easy deployment thanks to its modular and compact design.
