Energy-recovery cooling infrastructure

Cooling that pays you back

THERMEX makes a liquid-cooling kit for data center servers that also generates electricity from the heat it removes. You pay to cool the server anyway. Now some of that money comes back.

How it works

Heat you already pay to remove

A busy server runs hot all day, and the cooling system carries that heat away and throws it out. THERMEX sits in that path and turns part of the heat into electricity. The server stays just as cool as before.

01

The CPU heats up

Under load, each processor produces heat nonstop. Normally all of it is wasted.

→
02

The unit converts it

A solid-state module on top of the CPU turns part of that heat into DC power. Cooling keeps working as usual.

→
03

The server uses it

That power runs the server's own fans, pump and controllers, so it pulls less from the grid.

Why THERMEX

Why now

1

Buyers already pay for cooling hardware

Server makers buy liquid-cooling parts from outside suppliers. That channel exists and it is growing. We sell into it with a product that also gives power back.

2

Nobody else does this per CPU

Cooling companies cool. As far as we know, none of them put a separate energy-recovery unit on each processor.

3

AI is pushing everyone to liquid

AI chips run too hot for air. Data centers are moving to liquid cooling anyway, so we don't have to convince anyone to switch.

Market opportunity

Where the market is going

Liquid cooling is on its way to becoming the default in new data centers. Every server that switches is a server our kit can go into.

Technology

How it's built

Each processor gets its own conversion unit, with its own supply of cold coolant.

Solid-state conversion

Nothing moves in the electrical path. Because every unit gets fresh cold coolant, none of them is stuck with coolant that another CPU already warmed up.

If it fails, nothing breaks

If a conversion unit has a fault, the server simply goes back to its regular power supply. Cooling isn't affected.

Not a standard TEG

Our unit includes an advanced ionic interface layer we developed ourselves. It gets more out of the module than an off-the-shelf thermoelectric generator. The details are a trade secret.
