CDU with Leak Prevention
A comprehensive range of CDU with Leak Prevention that provides precision cooling to data centre environments.
About CDU with Leak Prevention
Aqua’s patented, award-winning, Leak Prevention System (LPS) technology, is at the heart of our CDU units and enables data centres to embrace the energy efficiency benefits of water-cooled cooling technologies, without any of the fears that can arise at the thought of exposing critical equipment to water. The Aqua LPS guarantees continual, leak-free operation. It isn’t a leak detection device; it prevents a leak from ever occurring in the first instance.

How does the Aqua Leak Prevention System work?
The LPS has a simple scientific principle at its heart – the Venturi effect. A Venturi tube turns the water pressure from positive to negative. Water always circulates at negative pressure. If any connection, hose, pipe, or other part of the data centre cooling circuit fails and creates a leak, air is drawn into it and carried within the fluid, preventing it from escaping.
Water is continually sucked through the system, carrying the air drawn in from the leak – wherever it is – back to the LPS and changed to positive pressure to remove the air via a vent to the atmosphere. A solid column of water is then recirculated, again under negative pressure. Even if a leak occurs, cooling is maintained.
- The cooling system will continue to operate unaffected, allowing remedial work to be organised and undertaken at a convenient point.
- The LPS system is modular, allowing multiple systems to be combined on the same pipework header flow and return pipes.
- Units are available with optional run and standby pumps, as well as non-ferrous options and various connectivity possibilities.
Why is the Leak Prevention System such a game changer?
Prior to the evolution of Aqua’s LPS, the only protection available if you wanted to deploy water-cooled equipment, was a leak detection system. These often relied on water leaking, running off pipework or spraying from a burst pipe, to activate an alarm and shut the system down. By this stage, the damage is done, and critical data and hardware have been compromised.
Detection systems are also very hit and miss – they need to be sensitive enough to alert personnel to a leak, but not overly sensitive to create false alarms. Leak detection tape, for example, must be regularly checked & maintained. Some facilities install two identical systems – using up valuable real estate and doubling costs – so that they have a fail-safe should a leak occur. Our LPS eradicates the need for this completely.
Award-winning Leak Prevention System
The LPS won a Queen’s Award for Enterprise: Innovation in 2015, one of the UK’s most prestigious business accolades. It also received a Commended Innovation Award from the Institute of Physics.
The LPS can be integrated with most data centre cooling technologies and is available on a supply only basis or as part of a complete cooling system.

Frequently Asked Questions
What is a CDU and what does leak prevention mean in a data centre context?
A CDU (Coolant Distribution Unit) circulates chilled water or coolant to server racks or in-row cooling units within a data centre. Leak prevention refers to the design features and monitoring systems built into the CDU to detect and contain any coolant leaks before they cause damage to IT equipment.
Why is leak prevention so critical in a data centre cooling system?
Even a small leak of coolant in a data centre environment can cause catastrophic damage to servers and storage equipment. The financial and operational impact of such an event can be enormous. Leak prevention systems give early warning of any issue so action can be taken before damage occurs.
What types of data centres are Aqua's CDUs suitable for?
Aqua’s CDUs are suitable for enterprise data centres, co-location facilities, high performance computing environments, and edge data centres. They can be configured to work alongside existing chilled water infrastructure or as standalone cooling loops.
Can Aqua integrate a CDU with existing data centre cooling infrastructure?
Yes. Aqua’s engineering team can design a CDU integration that works with your existing cooling plant and IT infrastructure. We can advise on connection points, flow rates, and control interfaces to ensure seamless operation.
What is the lead time for supply and installation of a data centre CDU?
Lead times depend on the specific configuration required. Contact Aqua’s Sales team with your data centre layout and cooling requirement and we will confirm availability and a realistic delivery and installation timeline.
