Passive Cooling

The science behind our materials

Atmospheric Absorbance

The atmosphere of the planet is transparent at some wavelengths and not at others. Due to the Greenhouse Effect, CO2 and other greenhouse gasses in our atmosphere absorb particles of light, causing the bonds between the atoms to vibrate, effectively trapping the photons and heating up the planet.

For example, this is why we see sunlight at the surface of the planet— visible wavelengths are not absorbed by the atmosphere. We are focused on targeting these spectral windows, but at longer wavelengths that are invisible to the naked eye.

Reverse Greenhouse Effect

We make hyper-emitters that selectively emit in the wavelengths where the atmosphere of the planet is transparent. 

When we do this, it is like taking the emitter out of an insulating thermos (the atmosphere) and exposing it to the vast cold sink of space.  Then, due to the second law of thermodynamics (heat always goes from hot to cold) the material gets cold without any additional energy or electrical input.

In other words, we are making use of the significant temperature differential between the surface of the planet and outer space, preventing atmospheric absorption by emitting specific wavelengths of light, and allowing the heat to go straight into space.

We like to call this a Reverse-Greenhouse Effect because heat is whisked away from the planet instead of getting trapped.

How CoolFilm revolutionizes industries

Cold Chain

Deploying onto temperature-controlled transportation vehicles (trucks, rail cars) significantly increases profits. This increase comes in two ways - reduced day to day diesel fuel usage and stress on the A/C units. This correlates to reduced GHG emissions via lower diesel fuel usage. The film applies in a similar way as a vinyl advertisement would and does not add any material weight onto the equipment. Once CoolFilm is deployed, the owner/operator of the equipment obtains the benefits without any more thought or effort.

Grid Infrastructure

Deploying onto equipment for the electric grid (such as BESS, Inverters, Transformers, Power Lines, Generating Equipment, Combiner Boxes, Switchgears etc.) significantly increases profits. This increase comes in a myriad of ways including increases in day-to-day efficiency, reduced annual maintenance, and increased longevity. The film applies very simply on the exterior of the equipment and can easily be cut during installation to ensure that all safety precautions are followed (i.e meters can be read, safety labels are exposed, doors can be opened). Once CoolFilm is deployed, the owner/operator of the equipment will obtain the benefits without any more thought or effort.

Data Centers

Deploying onto data centers (such as enclosures, piping, HVAC systems, telecommunications devices, power systems) significantly increases profits. Cooling provides a significant expense for data centers, as it is required for proper operation and reliable uptime. Profits increase directly through reduced cooling needs and maintenance costs related to heat but are also improved through increased fees driven by higher reliability than competitors. CoolFilm is durable enough to last for many years outdoors, yet nimble enough to be applied on any surface. This is critical for a data center, which often containers complex surfaces and structures. Once CoolFilm is deployed, the owner/operator of the equipment will obtain the benefits without any more thought or effort.

Dairy

Deploying in dairy operations (such as silos, tankers, piping, enclosures, pens etc.) significantly increases profits. This increase comes in two ways - reduced day to day diesel fuel usage to keep milk cool and fewer product losses. CoolFilm is durable enough to last for many years outdoors, yet nimble enough to be applied on any surface. For dairies, this is a critical combination because of their complex machinery in outdoor environments. Once CoolFilm is deployed, the owner/operator of the equipment will obtain the benefits without any more thought or effort.
