Maximize Valuable White Space
Cooling capacity shouldn't come at the expense of valuable white space. Deliver the cooling performance needed to support next-generation IT infrastructure in a compact footprint.
Modular Architecture - Compact modular construction maximizes cooling capacity while preserving valuable white space for IT infrastructure.
High Cooling Density - Deliver greater cooling performance within a smaller equipment footprint to make more efficient use of available floor space.
Bleeding Edge Components- State-of-the-art componentry ensures optimal operation and maximum performance.
A System Made to Scale
A facility that's outgrown its cooling platform is a facility stuck between a redesign and a bottleneck. Support everything from single server rooms to hyperscale AI deployments. Choose capacity that grows alongside your infrastructure instead of capping it.
Flexible Cooling Capacity - Scale up to 1 MW to match current and evolving cooling requirements.
Configurable Airflow - Upflow and downflow configurations adapt to your data center layouts and airflow strategies.
Custom Environmental Controls - Configure controls and optional humidification, heat, and ATS capabilities around your specific facility requirements.
Cut Operating Costs Without Cutting Corners
Lowering operating costs shouldn't mean gambling on reliability. Reduce energy consumption while maintaining the consistent conditions critical IT assets depend on.
ECM Fan Arrays - Reduce fan energy consumption and operating costs while maintaining reliable, consistent airflow.
Optimized Fluid Coil - Maximize cooling performance per unit footprint, making more effective use of available white space.
Optional Automatic Transfer Switch - Adds power-source resilience to help maintain operation through electrical supply interruptions.
Questions, answered.
A Computer Room Air Handler (CRAH) uses chilled water or another cooling fluid to remove heat from the data center environment and deliver conditioned air to critical IT equipment. CRAHs are commonly used in enterprise, colocation, hyperscale, and AI data centers where efficient, large-scale cooling is required.
