Liquid cooling is now widely used to manage heat in modern power and data centre systems.

Liquid cooling load banks, water cooled load banks, and glycol cooling systems all depend on reliable connections. These connections must be safe, clean, and easy to use.

We use the TODO® II Tank Unit with dry-break coupling technology to support tough cooling jobs in data centres, generator testing, and industrial load bank applications. The TODO® II system is also qualified to NATO STANAG 3756, highlighting its proven performance, safety, and reliability in demanding military and industrial environments.

We use proven dry-break couplings and a robust tank unit to move cooling liquids safely, without spills or air entering the system

Common Challenges in Liquid Cooling Load Bank System

Load banks produce a lot of heat during operation. This is common when they are used for:

  • Testing backup generators
  • Supporting large UPS systems
  • Commissioning data centre power and cooling equipment

In water cooled load bank and glycol cooling systems, standard hose or flange connections often cause problems. These can include:

  • Liquid leaks during connection or disconnection
  • Air entering the system and reducing cooling performance
  • Safety risks to operators
  • Longer setup and shutdown times

These issues are even more serious when the liquid cooling load bank is mobile or installed temporarily. Fast and clean connections are essential in these situations.

Our Approach: TODO® II Tank Units with Dry-Break Couplings

For these applications, we use the TODO® II Tank Unit as a key part of the cooling system. It provides a safe and simple connection point between the cooled load bank and the cooling circuit. 

This approach supports liquid cooled load and water cooled systems used for testing high electrical loads in high density environments, where reliable system components and efficient heat removal are critical.

The tank unit lets operators connect and disconnect hoses quickly. At the same time, it keeps liquids contained and the system protected.

  • Dry-Break Design: Liquid flow stops automatically when the coupling is disconnected. This prevents spills of water or glycol.
  • No Air Entry: The coupling design stops air from entering the cooling loop. This helps the system run efficiently.
  • High Flow Capacity: The system supports the high flow rates needed for large liquid cooling load banks.
  • Strong and Durable Build: The tank unit is built for repeated use in industrial and data centre environments.
  • Suitable for Water and Glycol: Works with water-based cooling and glycol mixtures used for temperature control and freeze protection.

The tank unit creates a fixed and protected connection point. This makes hose handling easier and safer for operators

Dry‑break couplings play a key role in modern cooling solutions. This is especially true in data centres and load bank testing environments.

When using liquid cooling load banks and water cooled load banks, dry‑break couplings offer clear advantages.

Main Advantages

  • Improved Safety: No hot liquid sprays or spills during disconnection.
  • Cleaner Work Areas: No fluid leaks inside data halls, plant rooms, or test areas.
  • Faster Setup and Removal: Quick connect and disconnect saves time during installation.
  • Reliable Cooling Performance: Prevents air from entering glycol cooling systems.
  • Reduced Fluid Loss: Protects treated cooling liquids and reduces environmental impact.

These advantages make dry‑break couplings a strong choice for repeatable and reliable water cooled load bank installations.
