CoolVault
- Up to 30,000 gallons of chilled water
- Vertical or horizontal configurations
- CFD-informed design
CoolVault™ thermal storage tanks are engineered to support stable, reliable performance in chilled water systems serving data centers and other mission-critical environments. Designed as ASME-certified pressure vessels, CoolVault stores chilled water to help manage peak demand, smooth load variability, and maintain consistent cooling delivery when system conditions change.
Unlike standard storage tanks, CoolVault is built with a strong focus on internal flow behavior and thermal performance. Proprietary baffling and CFD-informed design help preserve stratification and predict how water moves through the vessel before it is manufactured. The result is a PE-stamped storage solution that supports predictable system operation, not just added capacity.
CoolVault integrates directly into existing chilled water systems with minimal complexity. It provides a thermal buffer that helps chillers operate more efficiently and respond more smoothly to changing loads. This makes it a practical solution for data centers, central plants, and other high-demand applications where uptime and stability are critical.

Frequently Asked Questions
What does a CoolVault thermal storage tank do in a chilled water system?
CoolVault stores chilled water so cooling capacity is available when demand increases. This reduces the need for chillers to respond instantly to load changes and helps support more efficient cooling system operation.
How is CoolVault different from a standard storage tank?
CoolVault is engineered to manage flow and thermal behavior within the vessel. Its internal design helps maintain stratification and supports predictable chilled water system performance.
Is CoolVault the same as an ice storage system?
No. Ice storage systems freeze water to increase energy density, while CoolVault stores chilled water directly. This approach can simplify system design and integration.
Where is CoolVault typically used?
Common applications include data centers, central energy plants, and large commercial or institutional facilities with high or variable cooling loads.
How does CoolVault improve system stability?
CoolVault acts as a buffer between cooling production and cooling demand. By smoothing load fluctuations, it helps support more stable chiller operation.
What material options are available for CoolVault?
CoolVault is available in carbon steel or stainless steel construction to meet different application requirements and project specifications.
What configurations and sizes are available?
CoolVault is offered in both vertical and horizontal configurations, with capacities up to 30,000 gallons to accommodate a wide range of installation requirements.
