Inside the HCS
Production units at GW Modular's Houston facility: A-coil assembly, precision piping, and independently serviceable EC fan modules. The fastest way to a delivery slot is a conversation with Axel.



A cooling building block that scales with the hall
- Precision in-row cooling unit with ratings from 140 kW to 270 kW under validated operating conditions
- Chilled-water architecture at 480V, bottom-mounted fan arrangement, independently serviceable fan modules
- Integrated leak detection and drain pan
- Standalone, or 2-, 3-, and 4-unit frame configurations
- Scales in-row from 1 to 12 units per 72-foot pod, no hall redesign
- Integrates directly with GW Modular's hot-aisle containment architecture

What is the HCS Integrated Cooling System?
The HCS is GW Modular's factory-built precision in-row cooling unit for high-density and AI compute environments. It uses a chilled-water architecture at 480V with bottom-mounted, independently serviceable EC fan modules, and it is built and in production at GW Modular's Houston facility.
What cooling capacity does the HCS provide?
Each HCS unit is rated from 140 kW to 270 kW under validated operating conditions.
How does the HCS scale across a data hall?
The HCS installs standalone or in 2-, 3-, and 4-unit frame configurations, and scales in-row from 1 to 12 units per 72-foot pod with no hall redesign. It integrates directly with GW Modular's hot-aisle containment architecture.
What safety testing has the HCS completed?
The HCS is safety and performance tested and third-party evaluated to applicable UL requirements; UL listing in process.
