AXH-X-SUITE — DRY COOLING FOR HYPERSCALE DATA CENTERS

One platform.
Three scales.
Zero water.

WHY DRY COOLING

Built for maximum efficiency in a water-constrained world.

As demand for cloud computing and AI continues to grow, so does the need for efficient, large-scale cooling. Dry cooling uses ambient air to reject heat instead of water — an energy-efficient, environmentally responsible method that keeps facilities running where water is scarce, permitting is tight, and uptime can't be interrupted.

Power & PUE

Every fraction of PUE matters.

As AI drives higher rack densities and utility power becomes the limiting factor, dry-cooling architecture maximizes free-cooling hours to reduce operating costs and improve PUE.

The result is more available power for compute, enabling greater IT capacity, higher rack densities, and more efficient data center operations.

Water & permitting

Water scarcity is limiting where you can build.

Increasing water scarcity and stricter regulations are making water-dependent cooling more difficult to permit and deploy. Dry cooling eliminates water use, reduces regulatory risk, and enables faster expansion into water-constrained regions while helping hyperscale operators achieve their sustainability objectives.

SPEED & STANDARDIZATION

One design, deployed anywhere.

Hyperscale procurement depends on standard equipment, predictable lead times, and consistent spares. The X-Suite platform is factory-built to the same specification whether it ships to Phoenix, Dublin, or Singapore.

FREQUENTLY ASKED

Answers for engineering and procurement teams.

The questions our application engineers field most often, on the way to a site assessment.

Filter FAQs by:

Yes. Dry cooling can reduce the power consumed by the cooling system, leaving more of a data center's available electrical capacity for compute.

By maximizing free-cooling operation and reducing dependence on mechanical chillers, dry cooling architectures can reduce:

  • Chiller runtime
  • Cooling energy consumption
  • Maintenance requirements
  • Refrigerant use
  • Equipment replacement frequency

For power-constrained AI and hyperscale data centers, reducing cooling power demand can help make more capacity available for GPUs, CPUs, and other revenue-generating IT equipment.

More power for AI — not cooling.

In many hyperscale markets, utility power is the limiting resource. Dry cooling architectures:

  • Improve PUE by maximizing free cooling.
  • Reduce cooling power consumption.
  • Allocate more site power to revenue-generating compute.
  • Increase rack density within the same utility allocation.

Yes. Higher allowable coolant temperatures can increase the number of operating hours in which heat can be rejected to ambient air without compressor-based chilling.

As direct-to-chip liquid cooling becomes more common, dry coolers can become increasingly attractive as the facility-side heat-rejection system. Actual free-cooling capability depends on factors including climate, design temperatures, approach temperatures, and overall system requirements.

Same engineering discipline and manufacturing base, but different application. The X-Suite adapts our decades of heavy thermal equipment experience to the shipping dimensions, controls, and standardization hyperscale procurement requires, so the same platform can deploy across many sites without custom engineering each time.

X-Suite bays can be sized and staged to support N+1 and 2N configurations at the module level.

Common spares across Pod, Cluster, and Campus configurations also help keep redundant units interchangeable. During a site assessment, our applications team can map the project's target Tier requirements to the appropriate bay and fan configuration.

Yes. The platform ships to the same specification everywhere; the ClimateGuard package hardens it further for extreme sites such as desert dust, coastal salt, sub-zero freeze-thaw, or sustained 50 °C ambients, all without changing the base design your teams already know.

EcoTune ships with SCADA-ready telemetry out of the box, and our controls team supports standard BMS/DCIM protocols on request. Most integrations are scoped and validated during the site assessment, before the unit ships.

Yes. Walk a fully assembled module with your engineers at our facility. Compare drive options, walk the catwalks, and validate sound and access in person before you commit.

Most hyperscale projects ship with at least one site-specific spec, such as a custom coating, a controls integration, or a structural reinforcement. Our applications team engineers these against your load rather than forcing a standard fit.

X-Suite coolers are built to the same structural and corrosion standards as our industrial heat exchangers. A service life of 25+ years is standard, with galvanized structure, coated tube bundles, and common spares keeping maintenance costs predictable over that span.

Yes. AXH Service and Parts is a dedicated aftermarket division that repairs, replaces, and reworks coolers in the field, including units we didn't originally supply. Every X-Suite ships with a defined spares list and access to our field service team.

Yes. Pod is purpose-built for single-unit pilots and edge sites. Order one, prove the architecture on your site, then scale to Cluster or Campus using the same controls and spares.

Standard units run at 80 dBA at 100 ft. For data centers located near residential, commercial, or other noise-sensitive areas, the SilentOps package adds low-noise fan blades and a tuned acoustic enclosure to further reduce sound and help meet applicable local sound requirements.

Yes. The X-Suite is commonly specified as the dry heat-rejection loop for facilities running liquid or immersion cooling at the rack. Our applications team will size the cooler directly to your CDU or heat-exchanger loads.

Every X-Suite ships with our standard mechanical and workmanship warranty, backed by decades of experience building mission-critical thermal equipment. Extended coverage and service agreements are available through AXH Service and Parts.

Dry cooling architecture can improve reliability by reducing dependence on mechanical chillers and their associated compressors, refrigerants, refrigeration circuits, and complex control systems.

With fewer moving parts and the ability to operate in free-cooling mode whenever ambient conditions allow, dry cooling can reduce maintenance requirements and potential failure points while increasing overall system availability.

Where mechanical chillers are incorporated into the system, they can operate only when needed, reducing runtime and extending equipment life while providing cooling during the warmest operating conditions.
