Panju CoreVault Private Limited

Own your Data.
Control your AI.
Secure your Future.

A sealed, immersion cooled AI compute node that runs on zero cooling water and sits where the work is. Your data lives inside your machine, in your building, and nowhere else. Built in India, owned by you.

Why now

Rented compute stopped being safe.

Cloud regions are targets

In early 2026, drones and missiles knocked Gulf cloud data centres offline. Whole companies lost their compute and their data in an afternoon.

Small beats one big hall

Small nodes spread across sites beat one named facility. There is no single address whose loss takes your compute with it.

Power and water are running out

Where they run short, governments block new sites and the compute never gets built. CoreVault uses zero cooling water.

The problem

Three bad options, and you are asked to pick one.

01

Rent a foreign cloud

Your data sits in another country, on shared tenancy, under someone else’s law. You pay in dollars, and anyone who can reach that building can reach your work.

02

Buy loose AI servers

You inherit a cooled room, heavy power, water, floor space, permits and staff. The servers were the easy part.

03

Build a data centre

Years and crores before you see a win, and every model trained that way takes more power and water from the people next door.

The compute assembly mounted on its frame before immersion
Inside, before the fluid goes in. Standard server hardware on the immersion frame, nothing exotic to source or replace.

The solution

One machine that cools AI with zero water.

Fully immersed compute

The entire board, GPUs included, runs submerged in dielectric fluid. Quiet and dense, without the PFAS and pressure risk of two phase systems.

CoreVault control OS

Twelve live sensors, real power metering, autonomous thermal control and an automatic safety shutdown. The node reads itself, tunes itself and reports on itself.

Fits where a desk fits

A whole server room collapses into a sealed cabinet and one outdoor heat rejection unit, much like a split air conditioner.

The physics

Almost all of it reaches a chip.

Air cooled rack59% compute · 41% cooling and overhead

CoreVault node93% compute · 7% cooling and overhead

At PUE 1.7 nearly half the electricity in an air cooled room never reaches a chip. At 1.07 almost all of it does.

Start with what you run today, not with a purchase.

Data sovereignty

Defence grade by construction.

For work that cannot leave the country, the question is not how fast your compute is. It is where your data physically sits.

It never leaves the box

No foreign cloud, no shared tenancy, no cross border transfer, nothing to subpoena abroad. The data stays in your building because the machine is in your building.

It can run disconnected

A sealed unit on your own network, behind your own firewall. If the contract demands it, the node runs with no route to the internet at all.

Indian owned, Indian built

Designed, assembled and supported in India, on a patented architecture, billed in rupees, with a person you can call.

The repeating profile is the node holding oil against its setpoint on its own, with the radiator outlet tracking within a degree throughout. Oil stayed between 23 and 28.5 °C, flow between 8.18 and 11.09 L/min.

Why this holds up

Most people sell cooling. We sell a complete owned node.

A real patent

Our patent covers the autonomous immersion cooled architecture and its integrated self management. It is on record with the Indian Patent Office and published in the patent journal.

Integration, not parts

Anyone can buy GPUs or an oil tank. The edge is the combination: immersion cooling, a hardware safety watchdog and the control OS, in one machine.

India resident, INR billed

Dedicated infrastructure physically inside India, with no foreign exchange exposure and local accountability, which foreign clouds structurally cannot match.

And the economics work

It is cheaper because it is sustainable, not despite it.

The same design that keeps your data in the building also stops your compute from working against the environment.

Why I am building this

I came from operations: hospitality, then an MBA, then about nine years running execution in small businesses. What pulled me into compute was watching Indian AI builders pay foreign cloud rates, in dollars, for GPU time they could not get reliably, on infrastructure they did not control. Then I watched what happens when someone else's building goes dark and takes your work with it. CoreVault is my attempt to fix both: owned, immersion cooled nodes, run in India, billed in rupees, with local support.

Straight answers

What people ask before they book.

What is immersion cooling?

Single phase immersion cooling submerges the hardware in a non conductive dielectric fluid that carries heat away far more efficiently than air. There are no fans fighting hot intake air, no hot aisles and no room scale HVAC. The heat moves straight from the silicon into liquid and out through a compact loop.

How much power does a CoreVault node save?

A CoreVault node uses about 37 percent less facility power than an air cooled room, because almost all of the power reaching the machine reaches a chip rather than a cooling system. Cooling energy alone falls by roughly 90 percent.

Does it use water?

None. Not reduced, none. That matters in places where water is short and new sites are blocked on that basis.

Where does my data sit?

Inside your own machine, in your own building. There is no foreign cloud, no shared tenancy and no cross border transfer. If a contract demands it, the node runs with no route to the internet at all.

How much space does it need?

About 95 percent less floor area than a server room. A whole server room collapses into a sealed cabinet plus one outdoor heat rejection unit, much like a split air conditioner.

What does it do to hardware life?

Two to three times longer. Parts run at a steady low temperature instead of cycling hot and cold, which is what wears them out.

Is the technology protected?

Yes. Our patent covers the autonomous immersion cooled architecture and its integrated self management. It is on record with the Indian Patent Office and published in the patent journal.

Where is CoreVault built?

Designed, assembled and supported in Bhopal, Madhya Pradesh, and billed in rupees.

Your data, physically inside India.
