Nordran offers an online sensor that continuously measures reserve alkalinity in glycol‑based data center cooling loops, providing real‑time insight into acid generation and coolant degradation before pH drops. The low‑maintenance device integrates via Web, Modbus, or Ethernet/IP, enabling predictive maintenance to prevent corrosion, performance loss, and unplanned downtime.

Problem
Data center cooling systems rely on chemical buffers to prevent acid buildup, but traditional monitoring only tracks pH, which can remain stable until the buffer is exhausted, leading to sudden coolant failure, corrosion, and unplanned downtime.
Solution
Nordran provides an online sensor that continuously measures reserve alkalinity—the remaining buffering capacity—in glycol‑based cooling loops. By quantifying the stoichiometric consumption of the buffer, the system detects acid generation from biofouling, glycol degradation, corrosion, and additive breakdown long before pH drops. Real‑time data are delivered via web server, Modbus, or Ethernet/IP, enabling predictive maintenance workflows that schedule coolant replacement or treatment before performance loss occurs. The sensor is low‑maintenance, with automated sampling and optional slipstream, panel‑mount, or handheld deployment, making it suitable for harsh operational environments. Integration with existing control systems allows operators to monitor coolant health alongside other infrastructure metrics, reducing emergency interventions and preserving thermal efficiency.
Target Audience
Primary customers are data center operators, large‑scale IT facilities, and industrial cooling system managers who need reliable, predictive monitoring of coolant chemistry to avoid corrosion‑related failures.
