Parameter, a leading provider of mission-critical infrastructure monitoring systems, today announced the XD Series for RLE Leak Detection, a digital leak-detection platform purpose-built for liquid-cooled data centers. XD is built on an entirely new innovative technology stack that sets new standards for leak detection speed, precision, scale, and security. It enables facilities to automatically disable power and coolant flow to a specific rack the instant a leak is detected, virtually eliminating the impact of fluid hazards. Companies defining the next generation of AI infrastructure are already moving to adopt it.

“Single-phase direct liquid cooling accounts for the vast majority of liquid-cooled capacity coming online and every cold plate, manifold and quick disconnect adds a potential leak point an air-cooled hall never had,” said Alex Cordovil, Research Director at Dell’Oro Group. “Operators are specifying detection that traces a leak back to the exact joint, responds in seconds and scales across a hall without a specialist crew at every rack. Finding a leak that fast and that precisely means cutting power and coolant to one rack, not shutting down a whole pod and the revenue it carries.”

AI Data Center Market Momentum

AI racks now commonly exceed 100 kilowatts per rack, a load that air cooling can’t handle, and liquid cooling is becoming the standard in nearly every new facility. The direct liquid cooling market grew 156% year over year in the second quarter of 2025 alone. The hyperscalers and infrastructure providers are redefining what tomorrow’s data center looks like. That picture increasingly runs on direct-to-chip cooling, putting coolant inches from millions of dollars of silicon.

And the cost of failure has soared in part because every coolant line, hose and manifold adds another place where fluid can escape within a rack. A fully loaded high-density rack can top $3 million in hardware. Unplanned downtime costs AI enterprises up to $15,000 per minute, or $600 billion annually on average, and a single undetected leak can wreak havoc.

“Operators have trusted RLE Leak Detection systems to protect their most critical infrastructure for over 40 years. Our XD series brings the same level of operational visibility to the increased complexity of an AI data center,” said Mike Blazes, CEO at Parameter. “With Direct-to-Chip cooling, the acceptable response time for a leak event has gone from hours to seconds. XD is built to provide that caliber of response to all fluid lines in a data center, so our impact can be measured in racks saved.”

NVIDIA AI Factory Context

With $75 billion in data center revenue in a single quarter, NVIDIA is at the center of the AI buildout. Its influence extends well past silicon into how data center facilities are designed. In March, the company introduced its NVIDIA DSX AI Factory reference design and NVIDIA DSX blueprints for planning, building, and operating AI data centers as integrated systems of compute, power, cooling, and networking. These reference designs provide guidance for AI cloud and ecosystem partners building DSX AI factory infrastructure.

NVIDIA provided voice of customer during early conversations on XD Series development. The requests and recommendations shared by their controls architecture team were heavily valued throughout the engineering process to ensure the solution meets all quality requirements for the next generation of AI server architecture. NVIDIA’s engineering team is receiving early access to the unreleased XD Series units for demo testing and validation.

What Sets the XD Series Apart

The landscape of liquid-cooled architectures has unique concerns and continues to evolve. XD Series boasts several unique innovations engineered from the start to support the specific concerns of liquid cooling at any scale and any density:

  • The only quad-channel sensor units on the market. Four channels per sensor enable a branching topology that lets one compact unit comprehensively cover the multiple potential leak points throughout a Direct-to-Chip cooled rack.

  • The first fully PoE-powered leak-detection platform. The entire system, with more than 8,000 points, runs off a single switch, speeding alerts and dramatically simplifying installation by eliminating the need for external power supplies and reducing connections to a single cable.

  • The only leak-detection platform with native MQTT. The XD Series allows IT and cybersecurity teams to integrate XD directly into their primary DCIM without building custom middleware or air-gapping the system to meet security requirements.

  • The highest resolution on the market. Proprietary leak detection technology locates leaks to the nearest inch regardless of cable length, validates readings to eliminate false alarms, and alerts technicians by highlighting the exact server and coolant line affected, all in under 3 seconds.

  • Unmatched scalability. More than 8,000 digital zones and more than 2,000 simultaneous leaks located on a single controller mean an entire hall of racks maps to one system instead of a sprawl of panels.

  • Full stack redundancy. Localized relays at every system level enable redundancy and let facilities automatically isolate power and coolant to the leak-affected rack with sub-second latency.

Availability

The XD Series for RLE Leak Detection will be on display at SC26 in Chicago, November 15-19 and available for order on December 1, 2026. For technical specifications, please visit http://www.parameter-tech.com/XD-series.
