HydroCheck Automatic Water Shut Off System
The HydroCheck system offers zone monitoring for up to four independent areas, making it suitable for server rooms with multiple racks or aisles. Precision sensors deliver early leak detection, with a manual fault-clearing option for maintenance workflows. Rapid alerts come through bright LED indicators and relay outputs, helping teams respond quickly. Installation is straightforward via a DIN rail mount, allowing seamless integration into existing water detection networks in commercial settings. Ideal for critical infrastructure where early detection and fast shutoff are essential.
HydroCheck Water Leak Detector Replacement Puck
This replacement puck supports ongoing protection for server rooms by extending the detection network to additional zones. It is designed for compatibility with HydroCheck systems and can be wired into existing detection setups. The sensor set features reliable LED indicators and relay outputs to ensure prompt notification of leaks and rapid ACT mechanisms. Maintenance teams benefit from straightforward replacement without significant downtime, keeping critical rooms continuously protected.
E-SDS Water Leak Detector With Shutoff Valve
The E-SDS system integrates a leak detector with an automatic shutoff valve, aimed at preventing floods in both residential and commercial environments. Brass 3/4″ NPT ball valves enable effective control of water flow, and the device includes manual open/close and reset buttons for maintenance. It works across a range of domestic water lines and is suitable for kitchens, laundry areas, water heaters, and more. Vacation mode supports remote shutoff during absences, adding a layer of protection for server-room-adjacent facilities stored in the same building.
Water Leak Detector With 2 Sensors And Shutoff Valves
This system pairs automatic shut-off valves with multiple sensors to monitor water presence and trigger an alarm when leaks are detected. Brass 3/4″ NPT valves ensure compatibility with standard piping, while the controller handles audible alerts and centralized monitoring. Up to eight sensors can be connected, providing broader coverage for server rooms or utility rooms that require comprehensive protection against leaks and floods without relying solely on fire suppression or HVAC-aligned detection.
Cellular Leak Monitor With Temperature, Humidity & Power
The Hygge Apps cellular monitor provides 24/7 coverage with built-in SIM connectivity, removing the need for Wi-Fi. It tracks temperature, humidity, power status, and leaks, offering customizable instant alerts via text, email, or collaboration tools like Slack and Teams. The unit includes a year of cellular service and supports multiple users. This makes it suitable for off-grid server rooms, basements, or data centers requiring reliable, independent connectivity and rapid alerting for critical environmental changes.
Buying Guide
Key considerations when selecting a water leak detection system for a server room include coverage, integration, and response speed. Look for multi-zone capability to monitor cold aisles, hot aisles, and ceiling plenum areas. Automatic shut-off valves are critical in preventing floods from impacting racks and power supplies, so ensure valves are compatible with your piping (NPT sizing) and can be integrated into existing building management systems. Alert channels matter: choose systems that support LED indicators, relays, and remote notifications (SMS, email, Slack, Teams) to ensure rapid on-site and off-site response. Cellular connectivity is valuable for sites with unreliable Wi-Fi or network dependence. Finally, consider installation requirements, maintenance, and availability of replacement Pucks or spares to minimize downtime during scale-outs or renovations. For server rooms, prioritize systems with DIN rail mounting, robust sensors, and proven reliability in critical environments. Compare total cost of ownership, including installation, wiring, and ongoing monitoring fees, to determine the best fit for your data center’s risk tolerance and uptime objectives.
