Green Revolution Cooling (GRC) specializes in Data center cooling - in the business of immersion cooling - submerging the client's servers in a tank filled with liquid coolant, rather than using cold air - an approach that offers potential economic benefits to Data Centers by allowing them to operate servers without a raised floor, computer room air conditioning (CRAC) units or chillers. With their technology deployed in 13 countries around the world, customers are primarily in high-performance computing and cryptocurrency mining. Recent funding is allowing the firm to operationalize agreements with leading hardware OEMs (original equipment manufacturers) Dell and HPE, to expand several on existing customer sites, and add to its global footprint with a new office in India. SBIT involved from soon after the firm was founded, GRC has been in the forefront of the effort to increase the use of liquid cooling in the data center industry. The vast majority of data centers continue to cool IT equipment using air, while liquid cooling has been used primarily in high-performance computing (HPC). With the emergence of cloud computing and âbig data,â more companies are facing data-crunching challenges that resemble those seen by the HPC sector, which could make liquid cooling relevant for a larger pool of data center operators. In addition to supporting extreme power density, immersion cooling offers potential economic benefits by allowing data centers to operate servers without a raised floor, computer room air conditioning (CRAC) units or chillers. It also eliminates the need for server fans, which can also be power hogs. Servers operate in an enclosure filled with a dielectric fluid similar to mineral oil. They are are inserted vertically into slots in the tank, which is filled with 250 gallons of ElectroSafe fluid, which transfers heat almost as well as water but doesnât conduct an electric ch
