The new investment will equip the authority on liquid immersion cooling with the capital to accelerate new product development and capabilities while continuing to increase efficiency and reduce cooling costs for data centers.

AUSTIN, Texas–(BUSINESS WIRE)–GRC (Green Revolution Cooling), the leader in single-phase immersion cooling for data centers, today announced it has secured a $28 million C Series investment led by South Korea-based SK Lubricants. This most recent equity investment brings the company’s total funding to $43 million.

“We’re delighted to partner with SK Lubricants. This most recent investment will allow us to expand the important work we are doing to future proof the cooling infrastructure of data centers globally.”

The investment will provide GRC with the capital necessary to continue to build on the growth and milestones it has experienced over the last year, including a collaboration with Intel, significant end-user deployments with GRC Global Alliance Partners Dell, and Vertiv in the financial services, telecommunications, and HPC sectors, the establishment of a UK subsidiary, installation of the ICEraQ® Series 10 at the Texas Advanced Computing Facility, its recently initiated pilot program allowing data center operators to take liquid immersion cooling for a test drive, and last year’s

Last year, GRC secured the Data Centre World Innovation Product of the Year Award. The award recognizes GRC’s patented ICEraQ Series 10 immersion cooling system for its effectiveness in solving the problem of increasing heat loads in data centers and as a technology-based product aimed toward providing a brighter future.

“As the AI, the VR, and the self-driving industries are gaining traction, the high-density data center market is expected to grow dramatically,” said Cha Gyu-tak, CEO of SK Lubricants. “Not only will this equity investment in GRC maximize cooperation between the two companies, it will also help accelerate broader adoption of liquid immersion cooling by data centers and position us to be the first mover in the market while helping us grow into a liquid-based thermal management solution provider.”

According to a recent report from the Dell’Oro Group, revenue from the data center liquid cooling market accelerated in 2021 by nearly 65%, and in 2022 an additional 25% growth is expected. The increase is attributable to the adoption of cloud, colocation, and telco service providers. It is also estimated that early enterprise adopters will accelerate larger-scale rollouts.

“We’re delighted to partner with SK Lubricants. This most recent investment will allow us to expand the important work we are doing to future proof the cooling infrastructure of data centers globally,” said Peter Poulin, CEO GRC. “With the increased attention on data center efficiency and more broadly proposed environmental reporting standards for organizations across the globe, the investment will also help GRC contribute to a more sustainable data center environment while positively impacting the bottom line.”

While air cooling has been the dominant cooling solution in data centers, there is a power-density and geolocation point at which air cooling cannot compete with more efficient cooling methods. Liquid immersion cooling leverages higher thermal transfer rates to support high-density racks’ highly efficient and cost-effective cooling.

What is Immersion Cooling?

Immersion cooling is a cooling technique. Rather than cover the CPU and other chips with heat sinks, the whole motherboard is immersed in a liquid bath that keeps all of the hardware excellent. The tub is a non-conductive fluid that would not allow the electronics to heat up.

known as liquid submersion cooling, it is the practice of submerging computer components (or full servers) in a thermally, but not electrically, conductive liquid (dielectric coolant). Liquid submersion is a routine method of cooling large power distribution components such as transformers. Still rarely used for the cooling of IT Hardware, this method is slowly becoming popular with innovative data centers the world over. IT Hardware or servers cooled in this manner don’t require fans and the heat exchange between the warm coolant and cool water circuit usually occurs through a heat exchanger (i.e. heater core or radiator). Some extreme density supercomputers such as the Cray-2 and Cray T90 use large liquid-to-chilled liquid heat exchangers for heat removal.

Green Revolution cooling Collaborates with Intel.

Intel has recently collaborated with Green Revolution Cooling GRC, is a startup specialising in immersion cooling for server hardware, seeking to take immersion cooling mainstream.

The two companies announced a multi-year partnership that involves working with data center customers to develop and implement advanced immersion cooling techniques for future data centers. The two will look to test the safety and reliability of the technology for immersion-cooled racks running Intel Xeon Scalable processors.
