Designed, built and supported in India — sovereign by design
Your AI factory on sovereign Indian infrastructure: data residency under DPDP, MeitY-recognised, ISO 27001 / SOC 2 deployment paths, and procurement on GeM.
Overview
The DRACO 250 kW In-Rack CDU removes the heat that dense GPU racks generate — 250 kW of cooling via liquid-to-liquid cdu (in-rack), so today’s 700 W–1 kW+ GPUs run at full clocks without thermal throttling. It is the thermal layer that makes high-density AI racks possible on-premises, in INR, on a GST invoice.
Engineered to match RDP’s GPU servers, rack-scale systems and superclusters, it integrates with your facility water or runs closed-loop, and is delivered sized, plumbed and validated with the compute it cools — with leak detection and monitoring built in.
Key highlights
- 250 kW — rack/row-level coolant distribution.
- Liquid-to-liquid CDU (in-rack) — distributes treated coolant to cold-plate loops with filtration and control.
- Up to 400 L/min · PG25 / treated water — controlled flow and coolant chemistry for reliable, corrosion-safe operation.
- Leak detection & monitoring — sensors and BMS/DCIM integration for safe, observable operation.
- Supports 1-2 dense racks — sized to the density of RDP GPU racks.
- Quiet, efficient — liquid moves heat far more efficiently than air, lowering fan power and PUE.
- Validated with RDP compute — delivered as part of a tested, cooled rack.
- Make-in-India OEM — predictable INR pricing, GST tax invoice, pan-India onsite support, GeM-procurable.
Where it fits
- Dense GPU racks (primary): feeds direct-to-chip cold-plate loops across a rack or row.
- Rack-scale & NVL systems: the cooling that keeps NVL72-class racks within thermal limits.
- Retrofit or new build: design a liquid-cooled hall, or add density to a room.
- Edge/micro-DC: sealed/compact options for self-contained sites.
How it works
The unit isolates the rack coolant loop from facility water, controls flow, temperature and pressure, filters the coolant, and distributes it to the cold-plate loops. RDP sizes the loop, flow and coolant to your rack density and facility. Honest note: real cooling capacity depends on inlet water temperature, flow and rack layout — we size and validate it for your room.
Industry use cases
- AI data centres — cool dense GPU and NVL racks at full clocks.
- Government & national labs — sovereign HPC/AI cooling.
- Neocloud / AI providers — higher density per rack, lower PUE.
- Manufacturing & energy — HPC + AI thermal management.
- Edge & remote sites — sealed liquid cooling without a facility loop.
- Colocation — liquid-ready density in shared halls.
Performance — and how to be sure
We don’t publish inflated peak numbers. The honest picture: 250 kW at Up to 400 L/min cools dense AI racks within thermal limits given suitable conditions. Want certainty? Request a thermal assessment of your racks and room before you buy; we’ll size the solution and confirm the cooling capacity at your conditions.
Series & scale path
- DRACO (flagship thermal tier) — this.
- Capacity ladder: rear-door HX → in-rack/in-row CDU → row CDU → facility CDU (MW-scale).
- When to step up: grow from rack to row to facility cooling as density rises — talk to an architect about the loop.
Liquid vs air — the efficiency case
At 700 W–1 kW+ per GPU, air cooling hits its limit; liquid removes heat far more efficiently, enabling higher density, full clocks and lower PUE — and quieter rooms. The result is more compute per rack and lower energy cost. RDP pricing is fixed in INR with a GST input-credit-eligible invoice — ask for a PUE and density comparison for your room.
Software & integration
Integrates with your facility: BMS/DCIM monitoring, leak detection, flow/temperature/pressure telemetry, and alarms. Designed to match RDP GPU servers, rack-scale systems and superclusters.
Power, cooling & facility integration
A In-rack (full-height) unit — plan facility water (supply/return temperature and flow), power for pumps/controls, and floor/rack integration. (Exact capacity, flow, pressure-drop and connection figures confirmed in the thermal design.) Redundant pumps and monitoring available.
