Negative & Positive Cooling from Waste - A technology that turns waste or renewable heat into cold using a thermochemical solid-gas adsorption reaction and saves 80% electricity.

Their solution allows to use waste or renewable heat, instead of electricity, to produce cold. This way, energy losses are minimised while free, low quality energy (heat) is used instead of expensive, high quality energy (electricity).

Contrary to their absorption competitors, COLDINNOV's solution can efficiently produce negative as well as positive cooling, making it suitable for refrigeration (evaporation at -4°C), process cooling (+4°C) and air-conditioning (+12°C). In industrial, as well as mobile refrigeration facilities, they replace an energy intensive and noisy compressor with their static thermochemical reactor. All the other components (evaporator, condenser...) can be found ready to use on the current market, lowering considerably costs as well as failure risks. They use a natural refrigerant fluid (ammonia), which is both very effective and environmentally friendly.
