Protect Liquid-cooled Data Centers with Wireless Temperature Recorder

Liquid cooling solves the heat problem, but it creates a blind spot: the air around the coolant lines. When supply temperatures run close to dew point, condensation doesn’t announce itself—it just appears on a fitting. By the time someone sees it, the damage is already done. That’s why environmental monitoring in a liquid-cooled data center can’t be an afterthought. It needs to watch the air and the liquid together, in the spaces where wiring is difficult and downtime is not an option. This is where the Coeus Mini wireless temperature recorder earns its place—not as a convenience, but as the quiet line of defense between a controlled environment and a costly surprise.

Coeus Mini delivers reliable remote live data and instant alerts, well suited for liquid-cooled data centers temperature monitoring.

Compact Design, Easy Installation

The main unit features a slim design of 93mm*63mm*30.2mm, easy to install in limited spaces. The optional external probe flexibly extends to high-risk areas such as near the quick coupler and the lowest point of the pipeline, where condensation and leakage are prone to occur. 

Reliable network connectivity, Cloud Data & Optional API 

Coeus Mini real-time data logger offers flexible connectivity options to suit your needs: WiFi, 4G, or LAN. In areas with dense cabinets and severe metal obstructions, wired LAN is used to ensure stability; for difficult-to-wire locations, WiFi or 4G is employed for blind spot coverage. All monitoring data is automatically uploaded to cloud, enabling remote online access via mobile APP and cloud platform. API service is optional for system integration and secondary development.

Local & Remote Alarms, Stay Alert Anywhere

In data centers real-time temperature monitoring, accurate alerts, fast response and reliable delivery are also critical. Coeus Mini wireless temperature recorder supports local audible and visual alarms and remote SMS/email/APP push alerts, ensuring all operation and maintenance members are notified When the temperature goes beyond the preset range.

ISO/IEC 17025-Accredited Validation, Verified Data Accuracy

Freshliance sets up an ISO/IEC 17025 accredited laboratory. All products withstand regulated manufacturing processing and strict quality control.

As prescribed by ASHRAE TC 9.9, most liquid-cooled data centers run stably within 18–27°C. Coeus Mini wireless temperature recorder can effectively cover the measuring range with both its built-in sensor -20℃ ~ +60℃ and optional external probe -30℃~+70℃. moreover, the 0.1℃ resolution and ±0.5℃ accuracy ensure data reliability.
