Executive Roundtable: Converging Disciplines in the AI Buildout

In Q4 2025, data centers are frequently no longer singular builds; they’re now ecosystem projects shaped by AI-scale density, new cooling chemistries, and increasingly dynamic energy systems. To make sense of this shift, DCF convened leaders from Ecolab, EdgeConneX, Rehlko, and Schneider Electric to explore where design, operations, and sustainability now converge.

At Data Center Frontier, we rely on industry leaders to help us understand the most urgent challenges facing digital infrastructure. And in the fourth quarter of 2025, the data center industry is adjusting to a new kind of complexity. 

AI-scale infrastructure is redefining what “mission critical” means, from megawatt density and modular delivery to the chemistry of cooling fluids and the automation of energy systems. Every project has arguably in effect now become an ecosystem challenge, demanding that electrical, mechanical, construction, and environmental disciplines act as one. 

For this quarter’s Executive Roundtable, DCF convened subject matter experts from Ecolab, EdgeConneX, Rehlko and Schneider Electric - leaders spanning the full chain of facilities design, deployment, and operation. Their insights illuminate how liquid cooling, energy management, and sustainable process design in data centers are now converging to set the pace for the AI era.

Our distinguished executive panelists for this quarter include:

  • Rob Lowe, Director RD&E – Global High Tech, Ecolab
  • Phillip Marangella, Chief Marketing and Product Officer, EdgeConneX
  • Ben Rapp, Manager, Strategic Project Development, Rehlko
  • Joe Reele, Vice President, Datacenter Solution Architects, Schneider Electric

Today: Engineering the New Normal - Liquid Cooling at Scale 

Today’s kickoff article grapples with how, as liquid cooling technology transitions to default hyperscale design, the challenge is no longer if, but how to scale builds safely, repeatably, and globally. 

Cold plates, immersion, dielectric fluids, and liquid-to-chip loops are converging into factory-integrated building blocks, yet variability in chemistry, serviceability, materials, commissioning practices, and long-term maintenance threatens to fragment adoption just as demand accelerates. 

Success now hinges on shared standards and tighter collaboration across OEMs, builders, and process specialists worldwide. So how do developers coordinate across the ecosystem to make liquid cooling a safe, maintainable global default?

What's Ahead in the Roundtable

Over the coming days, our panel will also share their perspectives on other pressing Q4 industry themes, including:

  • The Economics of Acceleration: Compressed build cycles, shifting capex/opex tradeoffs, and the tension between speed-to-market and long-term efficiency.
  • Data Centers as Energy Ecosystems: Facilities producing, storing, and repurposing resources, requiring new grid partnerships and circular design models.
  • Beyond the White Space: Cross-disciplinary coordination as AI stacks grow more interdependent, demanding unified data, workflows, and lifecycle transparency.

Now let's move onto our first Executive Roundtable question for the Fourth Quarter of 2025.

Data Center Frontier:  As liquid cooling shifts from pilot deployments to baseline design, what new coordination is required among equipment manufacturers, construction teams, and chemical/process experts to standardize safe, maintainable systems across global portfolios?

Rob Lowe, Ecolab:  As liquid cooling implementations become more standard, scaling it safely requires deeper coordination across OEMs, construction partners, and chemical and process experts.

Direct-to-chip systems introduce new requirements around coolant chemistry, materials compatibility, corrosion control, and cleanliness, making early involvement of water and glycol experts essential.

To manage global portfolios, operators increasingly rely on standardized commissioning specs, consistent coolant quality baselines, and integrated real-time monitoring tools like our 3D TRASAR™ Technology.

Ultimately, designing for maintainability, not just performance, ensures these systems remain reliable, serviceable, and consistent across all sites.

Phillip Marangella, EdgeConneX:  The keyword is coordination:  

  • Coordination with the chip manufacturers on their latest reference designs and chip innovations.
  • Coordination with customers and their deployment requirements and rack density requirements.
  • Coordination with liquid to chip ecosystem vendors and partners on integrated liquid cooling solutions.
  • Coordination with internal stakeholders on the design, commissioning, and operating of data centers leveraging liquid cooling in support of AI Factories.

And lastly: Coordination with our upstream supply chain to ensure long-lead items as identified in the design process are available when we need them (or securing acceptable alternative options when necessary.

Ben Rapp, Rehlko:  As liquid cooling shifts from pilot programs to standard design practice, alignment across disciplines becomes essential. Success now requires earlier collaboration among equipment manufacturers, construction partners, and fluid chemistry experts to ensure interoperability, safety, and operational consistency at scale.

As a global energy systems provider, Rehlko plays a key role in ensuring power delivery, controls, and backup systems are engineered to meet the unique electrical and operational requirements liquid cooling introduces, both at commissioning and throughout the asset lifecycle.

Our focus is seamless integration, enabling operators to adopt and scale liquid cooling with confidence, reliability, and long-term performance in mind.

Joe Reele, Schneider Electric:  We see significant progress in this area as liquid cooling transitions from pilot deployments to baseline design.

Air cooling standards and thresholds are well established, and similar work is now being applied to the emerging liquid cooling space.

This shift requires new coordination among equipment manufacturers, construction teams, and chemical/process experts.

Coordination is essential to ensure systems are standardized, safe, and maintainable across global portfolios.
