As data centers adopt Direct-to-Chip (D2C) liquid cooling to manage the intense power densities of AI and HPC workloads, leak risks shift closer to the servers themselves. Coolant now flows directly through cold plates on processors, so even minor leaks at quick disconnects, manifolds, or hoses can quickly impact performance, cause waste, or lead to costly downtime.
Traditional room- or floor-level sensing often falls short in these tight, server-level environments. What’s needed is compact, high-sensitivity detection placed exactly where leaks are most likely — combined with robust, enterprise-grade remote monitoring.
TTK’s FG-DLC point sensor, paired with the FG-NET digital monitoring panel, delivers precisely that targeted protection.
Precision Detection for Direct-to-Chip Cooling
The FG-DLC is a compact, high-sensitivity point sensor designed specifically for conductive coolants used in D2C systems, including PG25 propylene glycol mixtures.
Key Advantages of the FG-DLC
- Ultra-fast detection of small leaks with low risk of false alarms.
- Compact form factor ideal for in-rack, above-rack, or cold-plate-adjacent placement.
- Pre-equipped sensing element for flexible positioning around high-risk connection points.
- Digital addressable technology with visible LED status indicators.
- Reusable design that supports long-term reliability and cost efficiency.
When connected to the FG-NET, each FG-DLC sensor becomes part of a fully addressable system. The FG-NET’s 7-inch touchscreen provides instant, precise leak location, supports multiple simultaneous alarms, and logs up to 5,000 events for detailed analysis.
Intelligent Central Monitoring with FG-NET
The FG-NET serves as the system’s powerful core.
Key Features of the FG-NET
- Real-time monitoring and instant alerts for any FG-DLC-detected leak.
- Intuitive interface with optional dynamic floor-plan mapping.
- Built-in TCP/IP and MODBUS/JBUS communication for seamless integration.
- Expandable via satellite devices (such as FG-BBOX) as your D2C deployment grows.
- Configurable relays for automated responses, such as pump shutdown or notifications.
This combination delivers server-level precision that traditional cable systems can’t match in dense, liquid-cooled racks.
Taking It Further: Advanced Remote Monitoring with VYKON by Tridium
For facilities that require deeper visibility, unified dashboards, and enterprise-scale remote access, the FG-NET integrates cleanly via MODBUS TCP or serial protocols into a VYKON by Tridium supervisory system (powered by the open Niagara Framework).
At FMS Integration, we specialize in this exact capability. Using VYKON, we can:
Benefits of VYKON Integration
- Bring FG-DLC and FG-NET alarms, leak locations, and status directly into your unified BMS interface.
- Create custom graphics, trend logs, and dynamic visualizations of your entire leak detection network.
- Enable secure remote monitoring and control from anywhere, with role-based access and mobile-friendly dashboards.
- Correlate leak events with other critical systems (cooling loops, power, environmental sensors) for faster diagnosis and response.
- Set up automated notifications, historical reporting, and compliance-grade logging.
This Niagara-based approach turns your TTK leak detection from a standalone safety system into a fully integrated part of your intelligent building or data center operations — giving operators complete oversight without needing to stand in front of the FG-NET panel.
Best Practices for D2C Deployments
When implementing FG-DLC sensors with the FG-NET (and optional VYKON integration):
- Position sensors at all critical connection points — quick disconnects, flexible hoses, and cold-plate interfaces.
- Leverage the FG-NET’s addressable naming for clear identification of each monitored rack or zone.
- Configure reaction times and relay logic to match your operational tolerances.
- Plan for future expansion by designing the system with headroom on the FG-NET bus.
