Green Revolution Cooling

Green Revolution Cooling (GRC) presents a specialized approach to data center thermal management, focusing on single-phase immersion cooling technologies. Established in 2009 by Christiaan Best, the company emerged with the goal of fundamentally altering how data centers are cooled to enhance efficiency and reduce operational costs. Best's background in engineering and a keen interest in sustainable technologies drove the development of the firm's core liquid cooling solutions.

The company's business revolves around designing, manufacturing, and implementing its proprietary immersion cooling systems for data centers of various scales, from small edge deployments to large hyperscale facilities. GRC targets a diverse client base, including high-performance computing (HPC) environments, government and defense installations, and enterprise data centers seeking to optimize their energy consumption and hardware longevity. The business model involves the direct sale of its cooling hardware, including rack-based systems and associated coolant fluids, as well as providing installation, maintenance, and consulting services. Revenue is generated from these hardware sales and ongoing service contracts.

GRC's flagship product line features patented single-phase liquid immersion cooling systems. Unlike two-phase systems, GRC's approach utilizes a dielectric fluid that remains in a liquid state, avoiding the complexities of boiling and condensation. This method involves submerging entire servers and IT hardware directly into the coolant. The primary benefit of this system is a significant reduction in cooling energy expenditure, reportedly cutting it by up to 95% compared to traditional air-conditioning methods. By eliminating the need for chillers, computer room air handlers (CRAHs), and raised floors, GRC's solutions enable a considerable simplification of data center infrastructure and a reduction in the physical footprint. Additional advantages include the protection of hardware from environmental contaminants like dust and moisture, which can lead to increased reliability and a longer lifespan for the equipment. The system's design allows for high-density server deployments, a critical factor for organizations running computationally intensive applications.
