When high-value compute performance is on the line, every particle matters.
As AI and high-density workloads drive the adoption of liquid cooling, thermal fluid networks are mission-critical to compute performance. A single contaminant, such as an air pocket or residual debris, can disrupt flow, impact heat transfer, and put performance at risk.
Vertiv™ PurgeRite™ NearZero™ delivers an engineered, closed-loop flushing process that reduces water use and minimizes waste during hydronic system commissioning. Unlike traditional methods that rely on continuous water input and discharge, Vertiv™ PurgeRite™ NearZero™ captures, treats, and reuses water on-site, reducing consumption, limiting wastewater, and simplifying site logistics.
The result is a more controlled, efficient commissioning process for mission-critical thermal systems, delivering greater predictability and environmental responsibility.
How Vertiv™ PurgeRite™ NearZero™ works
Engineer the flush plan
Vertiv™ PurgeRite™ develops a project-specific hydronic flushing plan designed around system size, flow requirements, cleanliness targets, and commissioning needs.
Capture and treat flush water on-site
Instead of sending flush water directly to discharge, Vertiv™ PurgeRite™ NearZero™ captures and treats it using on-site water recycling, filtration, and reverse osmosis processes.
Reuse water in a closed-loop process
Treated water is recirculated back into the flushing process, reducing the need for new makeup water and minimizing the volume that must be hauled off-site or discharged.
Reduce discharge complexity and project risk
By reducing water use, haul-off requirements, and discharge volume, Vertiv™ PurgeRite™ NearZero™ helps lower discharge management costs, simplify logistics, and support commissioning schedules.
Reduce water use, hauling, and discharge complexity during commissioning
Note: 1. Compared with conventional non-recycled flushing methods for closed-loop hydronic systems, based on industry-standard system volumes and modeled/documented project data. Actual results vary by system design, water quality, and site conditions.
Part of Vertiv’s fluid management and thermal lifecycle services
As high-density data centers rely on more complex primary and secondary fluid networks, commissioning practices must evolve. Vertiv™ PurgeRite™ NearZero™ extends Vertiv’s fluid management capabilities with a closed-loop approach designed to reduce water intensity, simplify discharge logistics, and support reliable startup of mission-critical hydronic systems.
