Liquid Cooling
Systems

Primary loops, secondary loops, CDUs, manifolds — engineered end-to-end for data centers operating at the frontier of AI compute.

What We Do

Complete Liquid Cooling
Engineering, Start to Finish

DCE Systems designs, fabricates, and commissions the full liquid cooling loop for AI and HPC data centers. We do not supply components — we engineer systems. From the initial thermal model through to loop commissioning, every part of the process is managed by our team.

Our systems are built around 316L stainless steel for all wetted surfaces, passivated per ASTM A967 to SFN-grade cleanliness standards. All piping systems are designed to ASME B31.3 and pressure-tested before commissioning. Welding is performed to AWS D1.6 certified procedures.

The result: liquid cooling infrastructure that operates reliably in the most demanding data center environments — AI training clusters, HPC, high-density mixed deployments — from day one and for years thereafter.

What We Engineer and Build

Primary loop piping and pumping skid system for data center chilled water distribution

Primary Loop Systems

Large-bore stainless steel piping systems connecting the chiller plant to CDU arrays. Includes pumping skids with variable frequency drives (VFDs), pressure and flow instrumentation, isolation valves, and all associated headers and branches. Designed to ASME B31.3 Process Piping standard. Pressure-tested before commissioning.

  • 316L stainless steel pipe to ASTM A312
  • VFD pump skids — single or redundant
  • Supply / return header systems
  • ASME B31.3 design and testing
CDU secondary loop system with manifolds for server rack liquid cooling

Secondary Loop & CDU

Coolant Distribution Units (CDUs) form the heart of the secondary cooling loop. DCE Systems supplies, configures, and integrates CDUs with the manifold systems, controls, and BMS interfaces required for production operation. CDUs provide heat exchange between the primary (facility) loop and the secondary (server rack) loop, with the secondary loop carrying a dielectric or corrosion-inhibited coolant directly to cold plates.

  • Single or dual-circuit CDU configurations
  • Plate-frame or shell-and-tube heat exchangers
  • BMS / DCIM integration
  • Flow, pressure, temperature monitoring
Overhead and floor manifold systems for data center liquid cooling distribution

Manifold Systems

Supply and return manifolds distribute coolant from CDUs to individual rack connections. DCE Systems designs manifolds for ceiling (overhead), underfloor, and in-row configurations — each with specific trade-offs for maintenance access, structural load, and integration with containment. All manifolds are fabricated in 316L stainless steel, passivated to ASTM A967, and supplied with all fittings, valves, and connections pre-installed.

  • Overhead / ceiling manifold runs
  • Underfloor distribution manifolds
  • In-row supply/return headers
  • SFN-grade 316L stainless — ASTM A967 passivated
Cold plates and quick-disconnect connectors for server GPU and CPU liquid cooling

Cold Plates & Connectors

In-server cold plates mount directly on GPU and CPU packages, providing direct liquid cooling at the chip level. DCE Systems sources and integrates cold plate assemblies compatible with major AI accelerator platforms, and supplies the quick-disconnect (QD) connectors that allow servers to be inserted and removed from the rack without coolant draining or spillage. All connections are leak-tested before delivery.

  • Cold plates for NVIDIA A100, H100, H200, AMD MI300X
  • Push-fit and dry-disconnect QD connectors
  • Leak testing and pressure testing included
  • Integration with rack-level manifold system
