Zone Chiller

The ThermalWorks Zone Chiller allows operators to run warmer, more efficient primary loops while delivering precise cooling exactly where it’s needed. The result is a decoupled primary loop from airside constraints built for the demands of high-density, AI-ready infrastructure that's aligned to the thermal realities of liquid-first compute environments.

Unlock Efficiency Without Sacrificing Cooling Performance

ENHANCED COOLING EFFICIENCY FOR AI 
Designed for AI workloads, the system improves cooling effectiveness and saves energy by precisely containing hot air and minimizing mixing with cold air.
ADAPTABILITY TO VARIOUS TECHNOLOGIES
The HAC offers compatibility when upgrading to liquid cooling solutions or optimizing existing air-cooled infrastructures.
EFFICIENT CABLE MANAGEMENT
The adjustable support arms for cable trays enhance overall cable organization andaccessibility, reducing potential interference.
RAPID DEPLOYMENT AND SAVINGS
Save up to 50% on labor with factory-assembled elements. ThermalWorks expert, ready-to-deploy crews ensure your containment solutions are installed promptly and properly.
Decoupled Efficiency
The Zone Chiller separates central plant performance from air-side cooling needs, enabling higher primary loop temperatures while still delivering the colder water required for air systems. This allows the primary loop to be optimized for liquid cooling performance, rather than constrained by legacy air-side temperature requirements.
Localized Cooling Architecture 
Rather than forcing low temperatures across the entire system, the Zone Chiller operates as a localized cooling layer that uses the warmer primary loop as a heat-rejection source to generate lower-temperature water only where air cooling is required.
Maximized Dry Cooling
The system significantly increases dry cooling hours by enabling elevated-temperature operation at the plant level, reducing reliance on mechanical cooling and improving overall efficiency.
Reduced Energy Consumption
With less need for continuous mechanical cooling, the Zone Chiller can deliver up to ~30% energy savings compared to legacy low-temperature, low-delta-T system designs.
Optimized for High Delta-T
Designed for large temperature differentials, the system improves thermal transfer efficiency while reducing pumping requirements across the cooling loop — unlocking the full efficiency benefits of ThermalWorks’ high-delta-T cooling approach.
Built for High-Density Environments 
As rack densities rise, the Zone Chiller enables air-cooled architectures to keep pace by delivering targeted cooling where it’s needed most.
