COLDINNOV, Expert in thermochemical and solar cooling

An innovative greentech company, COLDINNOV is developing two key fields of renewable cold production:

• We mainly focus on developing a breakthrough innovation in the domain of thermochemical cooling. As a matter of facts, our patented technology turns waste heat into sustainable cooling. To this end, we use a thermochemical solid / gas reaction and ammonia. Various sources of heat can be used, including industry, agriculture or tertiary; transportation (on sea, by trucks or rail); or even renewable sources (solar thermal …).

• On the other hand, COLDINNOV designs, manufactures and markets autonomous solar photovoltaic cooling units under the FREECOLD brand. Our range extends from the fridge to the milk tank and the cold room, and allows access to refrigeration even in areas not connected to the electricity grid.

Our solution: drawing cooling from waste heats

The technology developed and patented by COLDINNOV is based on a thermochemical solid / gas adsorption reaction using ammonia (NH3). A natural refrigerant, ammonia has no effect on global warming and the ozone layer, unlike the CFC gases used today.

This solution is an alternative to conventional refrigeration, provided mainly by compression systems and characterized by:

• Their energy consumption: they represent 15% of global electricity consumption

• Their refrigerant fluids: Fluoride-based, most are harmful to the ozone layer and amplify climate change

COLDINNOV solutions mitigate the impact of refrigeration on the environment by improving energy efficiency and recovering waste or renewable heat.

Without compressor, moving parts and quiet, the COLDINNOV system drastically reduces the consumption of cooling systems in electricity or fuel.

COLDINNOV’s innovation also lies in the adaptability of the technology to several power scales as well as to different energy vectors as the main source of heat. This allows to develop a wide range of applications in static cooling as well as in mobile refrigeration.

FREECOLD: our solutions for your access to off-grid cooling

FREECOLD by COLDINNOV is a well-know brand of autonomous solar refrigeration units. Made in France, our products are intended for the development of autonomous refrigeration infrastructures in regions with little to no connection to the electricity grid, or benefiting from strong sunshine.

In Africa particularly, between 20 and 40% of harvests are lost before being sold for lack of access to cooling facilities. Our solution thus allows to make the most of this continent’s exceptional sun power to favor the development of its agriculture.

We offer a whole range of solar cold rooms, milk tanks, air conditioners, refrigerators and freezers. Their input power comes either only from direct solar photovoltaic energy, or by a mix of solar power, batteries and grid when it is available. This allows FREECOLD products to better adapt to local needs and constraints.
