ElectroSafe® Single-Phase Fluids

In 2009, GRC took a disruptively simple approach to the problem of rapidly increasing processor heat and power loads in data centers – single-phase liquid immersion cooling with ElectroSafe fluids. With this cooling method, IT components are completely immersed in a steady-flowing dielectric ElectroSafe coolant, which has 1,200 times the heat capacity of air, which helps make single-phase immersion cooling a more effective method than other cooling technologies.

ElectroSafe encompasses a broad spectrum of high-performance, Earth-friendly, synthetic coolants that have undergone a meticulous selection and testing process. These fluids are globally available and have been deployed with GRC immersion cooling systems in more than 20 countries around the world, ensuring maximum performance, reliability, and compatibility with virtually every OEM server and IT component available.

ElectroSafe fluids are an indispensable feature of all our immersion cooling systems. Combined with ElectroSafe, our systems have been engineered to ensure maximum system uptime while maintaining its cooling capacity for the lifetime of a data center — 15 years plus — without any degradation.

ElectroSafe fluids are comprised of the following properties, enabling IT equipment to run efficiently and reliably day after day:

  • Earth-friendly
  • Odorless
  • Non-toxic
  • Synthetic
  • No GWP
  • Non-evaporative
  • Chemically-inert
  • Electrically non-conductive

ElectroSafe® Single-Phase Fluids–
Vastly Better Than Two-Phase Fluids

When it comes to immersion cooling, there are two primary technologies, two-phase and single-phase. Two-phase fluids change from a liquid to a gaseous state and then back again, continuously. They evaporate quickly, require a completely sealed environment, are significantly more expensive than single-phase fluids, and carry uncomfortably high GWP’s (global warming potential). Also, maintaining a two-phase system exposes technicians to inhalation risks from the highly volatile vapors of certain varieties of coolants and requires companies to make a big commitment to extra environmental issues. Extra precautions are required to maintain technician and operator safety.

On the other hand, ElectroSafe is always in a liquid state and never evaporates or needs to be replaced. Plus, unlike two-phase fluids, there are no health risks due to exposure, inhalation, or ingestion by technicians. Even maintenance gloves are optional, with many techs preferring not to wear them.

GRC immersion cooling systems are optimized to deliver the best cooling performance with ElectroSafe fluids. There is an ElectroSafe coolant that is suitable for every computing environment.

ElectroSafe Coolant Characteristics

What about fire and safety building code?

The National Fire Protection Association (NFPA) rates ElectroSafe Coolants as 0-1-0 to 1-1-0 or better. ElectroSafe fluids are classified as non-flammable, do not readily ignite, and pose no health hazard.

Upon installation, ElectroSafe will last the lifetime of the data center, not requiring a refill, even during hardware refresh
ElectroSafe protects immersed hardware from dust, moisture, corrosion, vibrations, and hot spots
