Turn Down the Heat! Gems Sensors’ Cool Technology for Hot Data Centers

Liquid cooling in data centers offers significant advantages over traditional air cooling, particularly as data centers grow in size and power density. It is more efficient due to the superior heat conductivity and higher heat capacity of liquids, especially water, than air. This allows for more effective heat transfer and better heat management in densely packed server racks.

Various methods for liquid cooling include direct-to-chip cooling, immersion cooling, rear door heat exchangers, in-row cooling units, chilled water systems with central chillers and Cooling Distribution Units (CDUs), and liquid cooling loops, which ensure efficient heat removal.

Liquid cooling supports higher-density server installations and requires less floor space for air handling units, allowing more room for IT equipment. Environmentally, liquid cooling reduces energy consumption and greenhouse gas emissions, and the extracted heat can be repurposed, promoting sustainability.

Liquid cooling systems rely heavily on sensors to monitor and control the cooling process. Gems Sensors provides essential monitoring and control solutions for maintaining these systems in data centers.

Key sensors include:

Flow Sensors to Measure Coolant Circulation

	Rotorflow and Turbine Flow Sensors
	Flow Switches

Level Sensors for Various Liquid Cooling Media and Leak Detection

	ULS-200
	Float-Type Level Sensors

Pressure Sensors to Detect Blockages or Leaks

	Pressure Transducers
	Pressure Switches
