Direct-to-Chip Liquid Cooling Systems

As AI and high-performance computing demands grow, traditional air cooling reaches its limits. Javelin Operations specializes in advanced liquid cooling infrastructure for next-generation data centers.

CDU Piping & Manifold Fabrication

Custom stainless steel piping from Coolant Distribution Units to server racks, including supply/return manifolds and quick-disconnect integration for GPU clusters.

Cold Plate & Immersion Cooling Support

Installation and commissioning of cold plate liquid cooling for CPUs/GPUs, and two-phase immersion cooling systems for high-density AI workloads.

Thermal Performance Validation

Flow verification, temperature differential monitoring, and thermal capacity testing to ensure design-intent cooling performance for mission-critical computing.

System Types We Support

Expertise across all chilled water system architectures and cooling technologies

Central Plant Systems

Traditional water-cooled chiller plants with cooling towers, primary/secondary pumping, and hydronic distribution to air handlers and CRACs.

In-Row Cooling

Close-coupled in-row cooling units for high-density server rows, with chilled water supply serving rack-adjacent cooling equipment.

Rear Door Heat Exchangers

Passive rear-door cooling solutions attached to server cabinets, using chilled water to remove heat directly at the rack exhaust.

Direct-to-Chip Liquid Cooling

Cold plate liquid cooling directly to CPUs and GPUs via CDU-supplied coolant loops, supporting high-density AI and HPC applications.

Immersion Cooling

Single-phase and two-phase immersion cooling systems with heat rejection via chilled water or cooling tower water loops.

Free Cooling & Economizers

Water-side and air-side economizer systems for energy-efficient cooling using ambient conditions when temperatures permit.
