DRACO 2.5 MW Facility CDU

Overview

The DRACO 2.5 MW Facility CDU is RDP’s flagship coolant distribution unit — 2.5 MW of heat removal that cools a full row-zone or a data-hall block of dense GPU racks. It is the facility-scale thermal backbone that makes the largest on-premises AI deployments possible, in INR, on a GST invoice.

Engineered to match RDP’s rack-scale systems, superclusters and supercomputers, it isolates the rack coolant loops from facility water, controls flow, temperature and pressure, filters the coolant, and distributes it across many racks with N+1 pumping — delivered sized, plumbed and commissioned with the compute it cools, with leak detection and monitoring built in.

Key highlights

• 2.5 MW · Up to 4,000 L/min — facility-scale heat removal for Up to 24 dense racks / a row-zone.
• Liquid-to-liquid facility CDU — isolates rack coolant from facility water; controls flow, temperature and pressure with filtration at scale.
• PG25 / treated water — corrosion-safe coolant chemistry for reliable long-term operation.
• N+1 redundant pumps — continuous cooling during maintenance and failures.
• Leak detection & monitoring — sensors and BMS/DCIM integration for safe, observable operation at scale.
• Efficient, low PUE — liquid removes heat far more efficiently than air across the hall.
• Validated with RDP compute — delivered as part of a tested, cooled data hall.
• Make-in-India OEM — predictable INR pricing, GST tax invoice, pan-India onsite support, GeM-procurable.

Where it fits

• Data-hall cooling (primary): distributes coolant to direct-to-chip loops across Up to 24 dense racks / a row-zone.
• Superclusters & supercomputers: the cooling backbone for halls of NVL72-class racks.
• New liquid-cooled facilities: the facility CDU layer between the racks and the building’s water loop.
• Scale-up cooling: add CDUs as the data hall grows.

How it works

The facility CDU forms a closed technology-cooling-system (TCS) loop to many racks, rejecting heat to the building water loop through large heat exchangers. It controls flow, supply temperature and pressure, filters and treats the coolant, and provides N+1 pumping for continuous operation. RDP sizes the CDU, loops and connections to your hall density and facility water conditions. Honest note: real cooling capacity depends on inlet water temperature, flow and hall layout — we size and validate it for your facility.

Industry use cases

• AI data centres — cool halls of dense GPU and NVL racks at full clocks.
• Government & national labs — sovereign HPC/AI cooling at facility scale.
• Neocloud / hyperscale operators — facility-scale density and low PUE.
• Large enterprise & energy — the largest HPC + AI thermal deployments.
• Colocation — liquid-ready density across shared halls.
• National research programmes — cooling for the largest clusters.

Performance — and how to be sure

We don’t publish inflated peak numbers. The honest picture: 2.5 MW at Up to 4,000 L/min cools a row-zone of dense AI racks within thermal limits given suitable facility water. Want certainty? Request a thermal assessment of your hall 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, the largest in the line.
• Capacity ladder: rear-door HX → in-rack/in-row CDU → row CDU → facility CDU (MW-scale).
• When to step up: add facility CDUs as the hall grows — talk to an architect about the loop and redundancy.

Liquid vs air — the efficiency case

At 700 W–1 kW+ per GPU, air cooling hits its limit; liquid removes heat far more efficiently across the hall, enabling higher density, full clocks and lower PUE. The result is more compute per facility 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, N+1-pump control and alarms. Designed to match RDP rack-scale systems, superclusters and supercomputers and standard facility water loops.
