Submer, a company specializing in cooling technology for data centers, has secured $55.5 million in investment. The funding round, amounting to $55 million, was led by M&G. Based in Spain, Submer’s investment round also included participation from Planet First Partners, Norrsken VC, and Mundi Ventures.

Founded in 2015 by Daniel Pope and Pol Valls, the company’s valuation has increased to $500 million with this investment. Submer announced that the new funds will be used to enhance its proprietary liquid cooling technology, increase market share, and attract new customers.

Submer is recognized as a company addressing the cooling needs of data centers. It employs a unique non-conductive liquid that is completely biodegradable, submerging servers in this liquid for cooling. This approach is more energy-efficient and provides better cooling compared to traditional air and water cooling systems.

The systems developed by Submer can recover heat generated by servers and redirect it for heating buildings or for use in other industrial processes.

Liquid cooling not only extends the lifespan of servers but also reduces noise levels, as it eliminates the need for moving parts like fans. The company serves major clients such as Telefonica and ExxonMobil and collaborates with significant server manufacturers including Dell, Supermicro, and Intel.
