Data Centre Immersion Cooling
If you're business requires high computing with low latency such a gaming, IoT, Edge or health. Immersion cooling would be the best cooling solution to handle the heat produced by constant running hardware.
Data Centre Immersion Cooling Solutions
Immersion cooling is increasing in popularity, especially with large data centres with densely packed high-performance computer systems and large numbers of server racks. Immersion cooling is the method of immersing a server into a dielectric liquid.
This type of liquid does not conduct electricity. Therefore, it is totally safe for the electronics components to be emerged without any risk of short cuts and oxidation. Immersion cooling is an alternative to traditional data centre cooling methods and has many benefits for businesses.
In these times of rising costs, energy and manufacturing issues, immersion cooling may become the most attractive option for businesses over traditional cooling methods.
Single-phase Immersion Cooling
With single-phase immersion cooling, servers and various hardware are totally immersed vertically in a coolant bath filled with a hydrocarbon-based dielectric liquid.
The heat produced by servers is transferred to the coolant through direct contact with the components. From there, It is sent to a cooling tower through a cooling distribution unit to be cooled and sent back in the tank.
All waste heat generated by the servers or hardware is captured by the dielectric liquid inside the tank, which is capable of absorbing around 1500 times more heat than air, for the same volume. The heat then flows to a heat exchanger where it’s cooled by a secondary air to liquid or liquid to liquid heat exchanger to be dissipated or recycled.
The Benefits of Using Single-phase Immersion Cooling
Compared to other cooling systems such as air conditioning, using immersion liquid cooling drastically decreases operating costs and requires little maintenance. Utilising single-phase immersion provides many advantages such as the below.
- Compact system offering layout flexibility
- Quiet operation
- Less space required compared to traditional cooling methods
- Reduction in operating costs such as electrical and water
- Eliminates airflow management
- Improved thermal efficiently with lower PUE
- Efficient and resilient cooling
- Reduces carbon footprint

Two-phase Immersion Cooling
Two-phase immersion cooling requires the servers or hardware sealed within a tank filled with fluorocarbon based liquid. This specifically designed liquid has a very low boiling point and the heat generated by the components causes it to boil.
The boiling fluorocarbon liquid is the core of the two-phased immersion system as the heat turns the liquid into gas causing a phase change. This gas goes through a water-cooled condenser coil which is placed at the top of these sealed racks. The vapor is then transformed into liquid which drops back into the main tank to be continuously recycled.
Recycling within a controlled immersion system allows a certain temperature homogeneity compared to other cooling methods such as air conditioning. The dielectric fluid will mitigate any sudden temperature changes which will improve the service life of servers and implemented hardware.
The Benefits of Using Two-phase Immersion Cooling
Although fluorocarbon is expensive and must be handled with care, there are many advantages utilising this two-phase system.
- Improved thermal efficiently with lower PUE
- Flexible deployment since immersion cooling tanks can be situated in most locations
- Quiet operation
- Reduction in operating costs such as electrical and water
- Eliminates airflow management
- Best efficiency in any form of cooling
- Less space required compared to traditional cooling methods
- Efficient & Resilient Cooling
- Approximately more than double in heat rejection compared to single-phase.
- Waste heat can be recycled
Comparing Immersion Cooling with Air Conditioning
If you compare immersion cooling to other traditional methods such as air conditioning, using immersion liquid will not only reduce your carbon footprint but drastically reduce operating costs which is vital in these times of rising electrical and water costs. Furthermore, immersion cooling provides in comparison a more stable temperate due to the immersion in dielectric fluid. This will extend hardware service life as there are less sudden temperature changes.
In most cases, the conventional data centre can reach up to around 92 decibels which creates a poor, loud and dangerous working environment where ear plugs must be required. If equipment is immersed, there will be no requirement for loud moving parts such as fans which will drastically decrease noise pollution within the data centre.
If you're business requires high computing with low latency such a gaming, IoT, Edge or health. Immersion cooling would be the best cooling solution to handle the heat produced by constant running hardware. Ensuring your data centre is running efficiently and keeping your hardware cool is essential to your business success. That’s why INFINITI offers the comprehensive and efficient data centre immersion services outlined above with expert installation and highly competitive pricing.

Climate Change: Is your data centre at risk?
For an insight of the climate change risk to UK data centres, earlier this year the Committee of Climate Change offered a detailed report. The authors pointed out that it’s difficult to make a quantitative assessment of the risks due to the lack of visibility into locations and connectivity arrangements of the UK’s private-sector data centres.
