Thanks to the energy of sound

We bring
cooling anywhere

OFF GRID SOLUTION

EQOOLER® turns waste heat into reliable cooling

Our patented solution (thermoacoustics technology) uses thermal gradient to amplify acoustic waves in a closed loop in order to turn heat into cooling without electrical consumption.
Acoustic loops can be packed into a single container to increase the cooling capacity.
In a 20 feet container we provide 100 kw of cooling at 5°C.

First killer app : solve gas turbine and genset derating in high ambient temperature regions and off grid situations.

APPLICATION ON

Offgrid cooling solutions markets

Due to economic development, the need for cooling is going to triple by 2050 (source IEA). There is a significant business opportunity for a new "off grid cooling solution" using free or recycled sources of power, such as waste heat (instead of electricity) for stationary or mobile applications in the following cases :

  • expensive electricity

  • no water access

  • lack or faulty grid
