DRACO 700 kW In-Row CDU

Overview

The DRACO 700 kW In-Row CDU is a high-capacity coolant distribution unit that cools a row of dense GPU racks — 700 kW of heat removal via liquid-to-liquid cdu (in-row), so racks of 700 W–1 kW+ GPUs run at full clocks. It is the thermal backbone that makes high-density AI deployments possible on-premises, in INR, on a GST invoice.

Engineered to match RDP’s rack-scale systems and superclusters, it isolates the rack coolant loop from facility water, controls flow, temperature and pressure, filters the coolant, and distributes it to the cold-plate loops — delivered sized, plumbed and validated with the compute it cools, with leak detection and monitoring built in.

Key highlights

• 700 kW · Up to 1,100 L/min — row-scale heat removal for Up to 6 dense racks.
• Liquid-to-liquid CDU (in-row) — isolates rack coolant from facility water; controls flow, temperature and pressure with filtration.
• PG25 / treated water — corrosion-safe coolant chemistry for reliable long-term operation.
• Redundant pumps — N+1 pumping for continuous cooling during maintenance.
• Leak detection & monitoring — sensors and BMS/DCIM integration for safe, observable operation.
• Efficient, low PUE — liquid moves heat far more efficiently than air, lowering fan power and energy cost.
• Validated with RDP compute — delivered as part of a tested, cooled deployment.
• Make-in-India OEM — predictable INR pricing, GST tax invoice, pan-India onsite support, GeM-procurable.

Where it fits

• Dense GPU rows (primary): distributes coolant to direct-to-chip cold-plate loops across Up to 6 dense racks.
• Rack-scale & NVL systems: the cooling that keeps rows of NVL72-class racks within thermal limits.
• New liquid-cooled halls: the row/zone CDU layer between racks and facility water.
• Scale-up cooling: add CDUs as rows and density grow.

How it works

The CDU forms a closed technology-cooling-system (TCS) loop to the racks, rejecting heat to the facility water loop through a heat exchanger. It controls flow, supply temperature and pressure, filters and treats the coolant, and provides redundant pumping. RDP sizes the CDU, loop and connections to your row density and facility water conditions. 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 rows of dense GPU and NVL racks at full clocks.
• Government & national labs — sovereign HPC/AI cooling at scale.
• Neocloud / AI providers — higher density per row, lower PUE.
• Manufacturing & energy — large HPC + AI thermal management.
• Colocation — liquid-ready density in shared halls.
• Research & higher-ed — efficient cooling for large clusters.

Performance — and how to be sure

We don’t publish inflated peak numbers. The honest picture: 700 kW at Up to 1,100 L/min cools rows of dense AI racks within thermal limits given suitable facility water. Want certainty? Request a thermal assessment of your rows and facility before you buy; we’ll size the CDU 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: add CDUs or move to a facility-scale unit 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 row 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 facility.

Software & integration

Integrates with your facility: BMS/DCIM monitoring, leak detection, flow/temperature/pressure telemetry, redundant-pump control and alarms. Designed to match RDP rack-scale systems and superclusters and standard facility water loops.
