ElectroCool is the trademarked brand name for a line of biodegradable, non-toxic, single phase dielectric heat transfer fluids manufactured by Engineered Fluids (the DBA of ChemFoundry, Inc.). ElectroCool is used primarily in single-phase liquid immersion cooling (SLIC) of electronics, computer servers, graphical processing units, and other semiconductors.

ElectroCool is a proprietary formulation of synthetic hydrocarbons designed to have a high heat density and enhance material compatibility with a wide range of elastomers and other materials used in the manufacture of electronics as well provide long term oxidation stability during use.

Applications
Single Phase Liquid Immersion Cooling of Electronics is the use of a non-conductive (dielectric) heat transfer fluid to remove waste heat from electronics by fully immersing the electronics in ElectroCool dielectric coolants. The dielectric coolant is then circulated and cooled via a heat exchange r that is connected to a chilled water source or dry cooler that transfers the heat into the atmosphere, ground water, or other heat dump. The term "single phase" relates to the fact that the heat transfer fluid does not undergo a phase change into a gaseous state at any time during the cooling process. The advantages of using Liquid Immersion Cooling for Servers in data centers is the ability to remove large amounts of heat at very lower energy costs due the elimination of air cooling infrastructures such as fans, A/C units, and other active cooling systems. Another advantage is the ability to easily recycle the captured heat from the fluid dielectric coolant using efficient heat exchangers for use in building hot water and heating systems. Single Phase Immersion Systems used in data center applications often provide a Power Usage Effectiveness rating of 1.05-1.09 depending on the application.

Kinetic Energy Recovery System (also know as KERS, or kers) is an automotive system for recovering a moving vehicle's kinetic energy under braking. KERs operate by capturing the kinetic energy of the vehicle through a hydraulic interconnection in the transmission or directly to the axle of vehicle to a flywheel or generator.. When transferred to a generator the energy is stored in high voltage batteries for later use during acceleration. Because of the extreme energy transfers made in short periods of time KERS units typically generate very high temperatures during operation are cooled directly with ElectroCool to ensure consistent operation and long term reliability.

Electric Motor Cooling. Both A/C and D/C electric motors can be cooled by direct contact with ElectroCool dielectric cooling fluid. In this application, the dielectric coolant is pumped directly into contact with the rotor and stator windings to provide direct cooling of the motor. In addition, the dielectric coolant is also used to provide lubrication of the rotor bearings and cooling for the electronic motor controller.

Ceramics Poling.  During the poling step in the manufacture of piezoelectric ceramics, a fired ceramic piece is cooled while being subjected to an applied electric stress. This process aligns the ceramic’s crystalline structure along a desired axis. Because of their thermodynamic and electrical insulating properties, ElectroCool Fluids are often used to cool and insulate the ceramic pieces during the poling process.

Power and Distribution Transformers and Switchgear can be effectively cooled with ElectroCool fluids. ElectroCool’s high dielectric strength, exceptional purity, and resistance to oxidation permit effective cooling, arc quenching and dielectric safety.

Cooling of LEDs, Vacuum tubes and other apparatus. Single phase immersion cooling can be applied to a wide variety of thermal management applications. ElectroCool Dielectric Coolants have a broad profile of material compatibility and have been successfully used in range of aerospace, military and commercial cooling applications.

Toxicity and Environmental Fate
ElectroCool Dielectric Coolants are nontoxic and non-hazardous to human or marine life1,2. No health effects are expected by ingestion of ElectroCool products3

ElectroCool Dielectric Coolants are highly biodegradable. In the standard CEC-L33a 28-day biodegradation test, ElectroCool’s base components are more than 96% biodegradaded.4

In the Microtox® test with bioluminescent bacteria, testing of ElectroCool Dielectric Coolants found no observable effects were detected for concentrations of 49,500 ppm of the water-soluble fraction.5

Global Warming Potential
Hydrocarbon products, such as ElectroCool Dielectric Coolants do not absorb UV wavelengths readily and also have a very short atmospheric lifetime. As such, they have zero global warming potential ("GWP") and a Ozone Depletion Potential (“ODP”) 6 of near zero. As such, ElectroCool Dielectric Coolants can be used in both open bath and closed loop systems.
