DRACO 250 kW In-Rack CDU

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.

Deployment, warranty & support

• Made to order, sized, plumbed and commissioned in India with the compute it cools; lead time confirmed at quote.
• In the box: CDU, fittings, sensors and controls; facility connection scoped at quote.
• Onsite warranty + AMC with pan-India coverage and an RMA/escalation path (exact terms confirmed at quote).
