COLDINNOV, Expert in thermochemical cooling
An innovative green-tech company, COLDINNOV focuses on sustainable cold production:
- We develop a breakthrough innovation in thermochemical cooling. This patented technology allows us to turn waste heat into sustainable cooling by using a thermochemical solid / gas reaction and ammonia. Heat can come from various sources, including industry, agriculture or tertiary; transportation (by sea, trucks or rail); or even renewable sources (solar thermal …).

Our solution: drawing cold from waste heat

The technology developed and patented by COLDINNOV is based on a thermochemical solid / gas adsorption reaction using ammonia (NH3). Unlike the HFC and HCFC gases used today, ammonia is a natural refrigerant that has no effect on global warming or the ozone layer.
Therefore, 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 a compressor or moving parts and silent, 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 us to develop a wide range of applications in static cooling as well as in mobile refrigeration.
