Liquid Immersion Cooling Tank

High-Density Immersion Cooling Solution For Future-Proof Data Centres

With growing data demands and rising server rack heat density in modern data centres, efficient cooling is more critical than ever. Immersion cooling offers an effective solution for heat dissipation, helping data centre operators address the challenges of increasing energy consumption and space limitations.

Our Liquid Cooling Immersion Tank operates at higher FWS and TCS temperatures, enhancing energy efficiency and reducing both partial PUE (pPUE) and overall PUE for the entire data center. With a proprietary tank design that ensures optimal coolant flow and thermal management, our systems require only half the space of traditional air cooling solutions.

How the STULZ Liquid Cooling Immersion Tank Works

Integrated CDU

Coolant Distribution Units (CDUs) separate the Technology Cooling System from the Facilities Water System, reducing the risk of leaks and cross-contamination for greater system reliability.

Our Liquid Cooling Immersion Tank features an integrated CDU, offering compact, space-saving cooling for smaller capacities. For larger capacities, the STULZ CyberCool CMU coolant distribution unit ensures efficient heat transfer across the entire system.

the Technology Cooling System and the Facilities Water System

Precise control for greater reliability

Thanks to its flexible and precise control, the Liquid Cooling Immersion Tank ensures maximum reliability during continuous operation. In addition, to achieve the highest standards of reliability and usability, STULZ develops the controller in-house, ensuring that software, hardware and liquid cooling units are perfectly harmonized.

 

Other advantages

  • User-friendly 7” touchscreen display with two-level password protection for easy operation
  • Primary PICV adjusts based on TCS loop supply coolant temperature to maintain the setpoint (optional PICV modulates based on TCS loop return coolant temperature)
  • Adjustable pump switchover time, typically set to 8 hours
  • Coolant level sensors for real-time monitoring
  • Temperature is monitored at different points in the tank and displayed on the touchscreen
  • PDU power usage is monitored and displayed on the touchscreen

FAQs

What is a liquid cooling immersion tank?

A liquid cooling immersion tank is a cooling system where IT equipment, such as servers, is fully submerged in a non-conductive liquid. Heat generated by the equipment is transferred directly to the liquid, allowing for highly efficient heat removal compared to traditional air-cooled systems.

 

How does immersion cooling improve energy efficiency in data centres?

Immersion cooling enables operation at higher Facilities Water System (FWS) and Technology Cooling System (TCS) temperatures, which improves overall energy efficiency. This helps reduce both partial PUE (pPUE) and total PUE, lowering cooling energy consumption across the data centre.

What role does the integrated CDU play in the immersion cooling system?

The integrated Coolant Distribution Unit (CDU) separates the Technology Cooling System from the Facilities Water System, reducing the risk of leaks and cross-contamination. This improves system reliability while enabling precise control of coolant flow and temperature.

How much space does an immersion cooling tank require compared to air cooling?

The STULZ Liquid Cooling Immersion Tank requires approximately half the space of traditional air-cooled solutions. Its compact design allows higher cooling capacity within a smaller footprint, making it well suited to high-density data centre environments.

Is the Liquid Cooling Immersion Tank suitable for high-density and AI workloads?

Yes. Immersion cooling is particularly well suited to high-density racks, AI workloads and high-performance computing environments where heat loads are extremely high and traditional air cooling becomes inefficient or impractical.

Are standard and custom immersion cooling solutions available?

STULZ offers both standard immersion tank solutions and custom-built designs. For applications exceeding 100 kW per system, customised tanks can be developed to meet specific capacity, layout and operational requirements.
