Modernising infrastructure design is critical to shaping the evolving data centre landscape as organisations strive to keep pace with rapid transformation. Shane McDaniel, Executive Vice President at Oxford Flow, discusses the importance of the pressure regulator in data centre facilities and how its performance can play a vital role in modern data centre power systems.
The global race to build data centres is usually framed in terms of scale. Hyperscale campuses, gigawatts of power demand, sprawling server halls and increasingly sophisticated systems dominate industry conversations and focus. Operators and developers focus, understandably, on the largest and most visible parts of the system.
But in complex infrastructure structures, reliability is rarely determined by the largest components alone. More often, it’s shaped by the small pieces of engineering that sit quietly between them.
One of the most overlooked of these is the pressure regulator. Generally treated as a commodity hardware, essential but fundamentally interchangeable. Yet in modern data centre power systems, particularly those relying on natural gas power generation, their performance can play a far more important role than many operators realise. Technologies operating in these environments must therefore be engineered to deliver consistent precision, stability and responsiveness under rapidly changing conditions.
Engines that never stop moving
Many of the components used in industrial gas systems were originally designed for a relatively stable operating environment. Utility networks and traditional industrial processes tend to experience gradual changes in pressure and flow, giving equipment time to respond.
However, data centre power systems live in a much more dynamic world. As of late 2025, the US alone hosts more than 4,000 operational data centres – nearly half of all the facilities worldwide. In these new
conditions, computing demand fluctuates, whether due to AI workloads or bursts of cloud traffic, and engines can ramp up and down rapidly. Fuel demand surges and dips in tandem, creating operating environments that legacy regulators were never designed to handle. This places greater technological demands on control components, which must maintain accuracy and stability even as system conditions shift rapidly.
In particularly high-density facilities like in Northern Virginia – home to the largest data centre hub in the world, where servers power nearly all the major AI and cloud services globally – the margin for error is minimal. Pressure regulators that lag or drift from their target pressure have a measurable impact on performance. Engines lose efficiency, mechanical wear accelerates and performance across multiple units can degrade simultaneously.
When ‘good enough’ is no longer good enough
These factors make it clear that traditional pressure regulators are no longer sufficient. Historically, pressure regulators in industrial gas systems were treated as standardised components, with operators selecting a tried and tested option based on familiarity and proven reliability. Performance differences were often assumed to be marginal and risk was low. Now, modern data centre power systems challenge that assumption. Rapidly changing loads, high-density facilities and tight uptime expectations mean standard is no longer enough. Here, innovation in pressure regulator design matters.
By combining compact form factors, faster response characteristics and simplified mechanical design, modern regulators are able to maintain precise pressure control. These design improvements also reduce routine maintenance needs, allowing operators to spend less time on service interventions and more time optimising overall system performance.
Their smaller footprint also means they can be integrated more easily into high-density engine rooms, freeing space for additional equipment and simplifying system layouts in constrained facilities. These improvements may seem incremental on their own, but when US data centres consume over 90 billion kWh of electricity annually, they translate to measurable gains in efficiency, reliability and operational resilience.
Precision in fuel delivery can’t be treated as an afterthought and therefore must be considered as a prerequisite for keeping systems running optimally at scale. By improving precision, footprint and maintenance demands, these pressure regulators not only enhance performance but also support long-term operational resilience and cost efficiency.
Reliability in the background
As data centres scale, reliability has moved from a ‘nice to have’ to a critical business driver. Campuses are being built quicker than ever and companies are expected to invest almost US$7 trillion in data centre infrastructure, with around 40% of this spend in the US alone. In such high-stakes environments, even small improvements can have outsized effects on an asset’s bottom line.
At Oxford Flow, our pressure regulators, designed specifically for these circumstances, ensure operational resilience in settings where uptime is mission-critical. By maintaining stability under dynamic
load conditions and simplifying integration in dense installations, they help operators protect both performance and profitability. Technologies developed for these environments are built to meet the same expectations of uptime, performance and reliability that define modern data centre infrastructure.
Pressure regulators may never be the headline technology in data centre infrastructure, but as data centre power systems grow in size, scale and complexity, those once-overlooked components are starting to matter more than many operators may have realised.
