In this segment of the Submer Tech pitch, the presenter outlines the mounting thermal challenges facing modern data centers, driven by AI, blockchain, edge computing, IoT, and ever‑denser semiconductor chips. He explains that conventional air‑cooled designs—raised‑floor airflow, cooling towers, and fans—are reaching a physical limit and waste up to half of the facility’s energy in moving air and evaporating water. Regulatory pressure for decarbonisation and the need to sustain Moore’s‑law‑driven density further make air cooling untenable. The speaker introduces SANMARI, a mandatory‑soon, full‑stack liquid‑cooling platform that integrates hardware, software, specialized coolant chemistry, and robotics. Digital sensors monitor temperature, flow, and fluid level, enabling precise fluid circulation through electronic components, eliminating fan power, cutting water use, and delivering superior total‑cost‑of‑ownership (TCO) and ROI. The pitch positions SANMARI as both an economic advantage and a compliance requirement for future data‑center deployments.

It doesn't make any sense. Basically, we can grab this heat and reuse it for other purposes also. You have heard probably on all this hype about AI, blockchain, crypto, all these crazy buzzwords. This means hardware within the same space generates much more heat, like a light bulb from decades ago that irradiates a lot of heat. And on the other hand, you see trends around Edge computing, connected cars, IoT, smart cities, all these extra buzzwords, which means decentralized compute anywhere. So basically increased cost of maintenance and more data centers popping up everywhere. Like in the automobile industry many decades ago, we have to move to liquid cooling. There is a physical limitation to the capacity of basically getting the heat out of the compute using existing air-cooled technologies. So basically we are creating all this race with semiconductor companies— Intel, NVIDIA, AMD— all these companies try to get more out of all these chips, and to do so they pack more transistors, all this Moore's Law and so on, which eventually creates more power fit into a small space, these chips, you know. So basically we need cool liquid cooling to be able to keep up with this speed of growth of densities. So, SANMARI is not only compelling under the total cost of ownership and ROI, but actually will be mandatory, and it's already started to be mandatory in some places due to these decarbonization regulations and these chip densities. This is how a data center usually works. All these aisles of racks for basically, in some cases or most of the cases, enclosed so that you can feed air conditioning Air cooled through this raised flooring, and then it passes through the racks. And then on the other side, or behind the scenes, you have heat exchangers and cooling towers that consume a lot of electricity and evaporate a lot of water. Half of this energy is waste. It's basically for moving air, basically cooling, AC to DC power conversion. And when you zoom in where the value is, the IT equipment, you notice that Around 10 to 30% of the compute consumes energy for fans, for moving air within the computers. We basically eliminate all this waste. How we do it? We created this full-stack technology— hardware, software, chemical, now also robotics technology— that basically has digital temperature, flow rate, and level sensors and allows us to move a fluid throughout the electronics and dissipate the heat
