FG-DLC
Smart Cable Technology for Coolant Leak Detection
Reliable Point Sensor Designed to Detect Coolant Leaks
The FG-DLC is a digital sense cable designed specifically for detecting leaks of glycol and other coolants commonly used in data centers and HVAC systems. When installed around critical equipment, it provides fast, accurate alerts the moment a leak is detected—helping prevent costly downtime and damage.
Ideal for under-floor piping around CRAC/CRAH units and chiller lines, the FG-DLC integrates seamlessly with TTK digital controllers to provide precise fault identification and fast response.
Product Features
➟ Flexible Integration— Works seamlessly with FG-NET and other TTK controllers, providing local or centralized monitoring, BMS integration and scalable protection.
➟ Targeted Coolant Leak Detection— Detects glycol and water-based coolants, ensuring sensitive cooling systems are continuously protected.
➟ Reusable and Easy to Maintain— Unlike single-use alternatives, the FG-DLC can be cleaned, dried and reused after a leak event—lowering long-term costs.
➟ Digital Addressability— Each FG-DLC cable is individually addressable, allowing controllers to instantly identify and report the exact cable where the leak occurred.
➟ Durability in Harsh Conditions— Built with corrosion-resistant materials, the FG-DLC maintains sensitivity and accuracy even in demanding environments.
When a leak is detected on the FG-DLC sense cable, the device blinks red and the connected digital unit responds by—
Triggering an audible alarm and activating a relay
Displaying the fault type (leak or cable break) and FG-DLC address on screen
Sending an event report to the BMS via MODBUS/JBUS
Designed for environments where reliable cooling is critical—such as data centers, healthcare facilities and industrial plants—
The FG-DLC offers dependable, digital coolant leak detection that helps protect infrastructure and equipment!
