Application Overview

Chilled-Water System Readiness

How Javelin's flushing, chemical cleaning, passivation, temporary systems, and water management apply to chilled-water systems — preparing them for commissioning and startup.

Overview

Preparing Chilled-Water Systems for Startup

Chilled-water systems — from traditional central-plant hydronics to direct-to-chip liquid cooling — must be clean, chemically stable, and hydraulically proven before the first chiller or CDU is brought online. Javelin applies its specialized capabilities to get them there.

This is an application overview. For detailed scope information, see the individual capability pages linked below.

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.

Why Choose Javelin for Chilled Water Systems

Mechanical Flushing

High-velocity flushing removes construction debris, weld slag, and particulate from chilled-water piping — achieving the cleanliness levels your chiller manufacturer requires. Learn more →

Chemical Cleaning & Passivation

Chemical treatment removes mill scale, corrosion products, and surface contamination. Stainless-steel passivation restores the protective chromium oxide layer. Learn more →

Water Management

Sourcing, delivery, treatment, and coordinated disposal of flush water — including closed-loop recovery where site conditions allow. Learn more →

Temporary Systems

Temporary pumps, hoses, filtration, and storage deployed for the flushing and chemical phases — keeping the permanent plant out of the construction path until it's ready.

Commissioning Support

Javelin supports the commissioning process by delivering clean, chemically stable, hydraulically proven systems ready for Cx testing — with complete QA documentation and turnover records.

Fast Mobilization

Data center schedules are aggressive. We mobilize quickly, work efficiently, and coordinate seamlessly with general contractors, MEP firms, and commissioning agents to keep projects on track.
