One closed-loop liquid-cooling architecture built for high-density AI racks is designed to cut facility cooling water consumption from roughly 2.6 million gallons per megawatt per year for a conventional cooling-tower system to near zero, up to a 100 percent reduction, provided the loop stays sealed for the life of the facility. Waste heat recovery is already warming tens of thousands of homes in cities that have built the infrastructure for it. Both depend on hardware that holds up for the full service life of the facility.
Water Savings Depend on a Sealed Loop
A closed coolant loop only delivers its water savings if it stays closed. Porosity control and heat-affected zone management keep a closed-loop system closed for the life of the facility instead of leaking water and coolant it was designed to conserve.
Recovering Heat Instead of Wasting It
A growing number of facilities capture waste heat rather than exhaust it. In Stockholm, some 20 data centers and industrial suppliers feed heat into a 3,000-kilometer district heating network, delivering enough energy to warm the equivalent of 30,000 modern apartments a year. In Finland, a Nebius data center recovers about 20,000 megawatt-hours annually, enough to heat roughly 2,500 Finnish homes, and Google's Hamina facility supplies 80 percent of its local district heating network's annual demand. In Paris, Equinix's PA10 data center recovers heat from customer servers at 28°C, raises it to 65°C through heat pumps, and delivers roughly 10,000 megawatt-hours a year to the network that heated the Olympic Aquatics Centre during the 2024 Games, heat Equinix supplies free of charge under a 15-year commitment.
Cooling and the rest of a facility's non-IT infrastructure add meaningfully to a data center's total energy draw: the industry's weighted average power usage effectiveness was 1.54 in 2025 and has sat above 1.5 for six straight years, which means overhead adds more than half again on top of the electricity the IT equipment draws on its own. Recovering that heat instead of exhausting it means moving it through heat exchangers and piping that must hold up under continuous thermal load for the life of the facility, the same weld integrity problem we solve for cooling loops. A leak or a failed joint in a heat-recovery line wastes both the coolant and the energy value the system was built to capture.
Reliability Extends the Life of the Hardware Itself
Operators building data center hardware treat equipment reliability as a key requirement for how long that hardware can stay in service before it becomes waste, naming extending the useful life of racks, servers, and components as one of the primary tools for reducing hardware waste, with reliability benchmarking an important element in judging whether a life extension is feasible at all. We verify every weld in-house through our metal sectioning lab before it ships, because a joint that holds up under years of thermal cycling and pressure is a joint that doesn't need replacing early.
A closed loop, a heat-recovery line, or a cold plate assembly delivers the resource savings it was designed for only as long as the welds holding it together hold up. That is the standard we build every weld to.
That work happens at our facility, on the individual components. If water use, energy recovery, or component longevity are part of your data center program's goals, we would like to talk about the welding behind it.
