The latest cooling products for HPC in 2023
A round-up of the latest cooling technologies for scientists using HPC to support their research.
Cooling technologies continue to adapt to meet the changing demands and requirements of HPC users. Alongside growing demand for heat-dissipating products, other factors in choosing cooling solutions include increasing server density, infrastructure, costs, maintenance and support. This article highlights several providers delivering methods from RDHx to direct liquid cooling, passive loop cooling and immersion cooling - accommodating HPC users with varied requirements.
Start by determining the total power requirements for a server. This helps to estimate how much heat you will need to dissipate. For single CPU servers, RDHx or liquid cooling will most likely be sufficient; dual socket servers with power-hungry CPUs or multiple GPUs will draw substantially more power. These require more complex technologies such as direct liquid cooling, passive loop cooling or even immersion cooling.
However, while underlying power requirements are key to choosing the right solution, there are other factors; available data centre space, infrastructure, maintenance and support - along with technologies such as chillers or evaporative cooling - all need to be considered to find the right solution.
Featured cooling product: CHx200
Complete research with confidence as you benefit from decreased system downtime and increased capabilities. The CHx200 is a rack-based coolant distribution unit (CDU) built for today’s most demanding datacenter requirements. Coupling this CDU with CoolIT’s passive coldplate loops (PCL) containing patented split-flow coldplates, the CHx200 manages 200kW of heat load, providing cooling for up to 200 servers in a remarkably small 4U space.
The CHx200 contains an extremely efficient heat exchanger capable of utilising ASHRAE W4 warm water to manage server heat. As a result, users can expect a significant reduction in data center OPEX, allowing spending to be shifted to additional computing purchases.
Its Command2 Control System intelligently manages the CHx200’s centralised pumping system, ensuring target flow and pressure settings are maintained. The centralised pumping system provides superior reliability, performance and serviceability compared to distributed pumping systems (pumps attached to each cold plate).

Featured cooling product: Statepoint
Data centre professionals looking to build the next big thing, need a cooling system that can keep up. Nortek Data Center Cooling StatePoint Indirect Cooling Technology brings reliability and optimum performance to any data centre, regardless of location or climate.
This revolutionary technology delivers a solution that is better for business and the environment. StatePoint uses an indirect evaporative cooling method with a unique semi-permeable membrane exchanger that completely separates water from the air stream to prevent cross contamination. The result – significant power and water savings (as much as 30 per cent) and minimised risk for biological growths, such as Legionella.
StatePoint easily integrates with a variety of systems to offer a complete cooling solution. The unit can use recycled water, interface with waste heat recovery systems and operate off wind and solar power to help data centres take the next step toward net-zero operation.

The award-winning ColdLogik Rear Door method is best described by the term ‘Air Assisted Liquid Cooling’ or AALC. AALC allows for the best of both worlds; it enables higher densities in standard data centre designs, bringing efficiency to your next retrofit or build project.
Ambient air is drawn into the rack via the IT equipment fans. Hot air is expelled and pulled over the heat exchanger, assisted by EC fans mounted in the RDC chassis. Exhaust heat transfers into fluid within the heat exchanger; the newly chilled air is expelled into the room at or below a temperature chosen for sensible cooling.
CoolIT Systems Direct Liquid Cooling (DLC) uses the thermal conductivity of liquid to provide dense cooling to targeted areas. Using DLC and warm water, dependence on fans and expensive air handling systems is drastically reduced. This results in much higher rack density, overall reduced power use and significantly higher potential performance.
An EcoCooling direct evaporative cooling system can reduce IT or data centre cooling costs by up to 90 per cent, comply with ASHRAE 9.9 and produce a PUE (Power Usage Effectiveness) of under 1.1.
In Nordic and Arctic climates where temperatures never exceed 25°C, fresh air can be used all year round to cool a data centre. However, in warmer conditions, or when cooler inlet temperatures, are required, free cooling alone cannot meet required conditions. Supplementary cooling is required on hotter days. EcoCooling uses direct evaporative cooling in their products as a reliable, energy efficient alternative to refrigeration.
Green Revolution Cooling’s (GRC) patented immersion cooling technology creates favorable budget economics, reducing server energy by 10 to 20 per cent. GRC’s data centre solutions future-proof your operation, reliably cooling up to 100 kW/rack.
