At Nexalus we view data centres not only as hubs for processing data, but as thermal power stations. Predominantly known for performing instructions required to operate a computer, a CPU also converts the entire electrical input into thermal energy, which can be subsequently captured.
CPU- Untapped Potential
CPU- Untapped Potential
A CPU, primarily made of silica, when utilised correctly is extremely effective at converting electrical energy into thermal output due to the materials favourable electrical and thermal properties.
CPU- Untapped Potential
We have developed patented technology to lift thermal energy at a water temperature suitable for reuse. All of the historically wasted CPU thermal output of data centers, which is the entire electrical load, can now be redeployed to heat homes, buildings and green-houses among other possibilities.
A New Approach
Nexalus have created a number of patents and solutions that capture virtually all of the thermal energy in a 1U server configuration, while reducing Capex and Opex, enhancing CPU processing speeds and increasing compute density. We enable data centers to be the New Green Energy Source, as the thermal energy captured is also available in a liquid stream facilitating a fully circular economy.
Step 1
First, we reconceived liquid cooling of high-powered server processors. With the server as the design foundation, our patented 1U dual-plenum, water-cooled heat exchanger emerged – engineered to focus high-impact-velocity-microjets exactly where needed. Microjet cooling is so intense, low volume flow and pressure loads are required.
Step 2
Next, we designed a new concept for air-cooling of the supporting low-powered electronics. With the consistent engineering goal of solving problems where they happen, we embedded air to water heat exchangers – engineered to circulate cooled air to, and recover heat from these components – all within the 1U server form.
Step 3
Finally, servers can now be stacked to maximum capacity within the rack, with all of the heat recovered in our bespoke cooling system. The stand-alone sealed modular racks are plug-and-play, into an immensely simplified data center cooling and heat recovery infrastructure. This changes everything.

PUE + ERF = A CIRCULAR ECONOMY
In order to close the circular economy, the currently wasted thermal energy needs to be redeployed. This cannot be achieved using air due to the poor thermal physical properties of this fluid; water cooling is the most obvious and technically viable solution to this problem which will allow data centers to bridge the gap to becoming a truly circular economy.
Water has superior thermal properties enabling up to twice the thermal design power of a CPU and the transport of ×4,000 the thermal energy per unit volume as compared with air. Adopting water cooling facilities increased compute density, removes geographical constraints and increases profits.
Using water to improve server cooling and computer performance, the waste heat energy generated can also be transformed into a continuous revenue stream and allow your data center to contribute to the circular economy. At Nexalus, we have engineered solutions which can remove the need to choose between the performance, profit or effect of your data center on the planet.
Although PUE of data centers has been reducing over the past decade, the global average is circa 1.6, meaning data centers use 60% more electrical energy than is required for computing alone. As it stands, the global average for the energy reuse factor (ERF) is practically zero. This implies that a negligible amount of data center energy is being reused.
