Step into the future of energy


Thermoacoustic Energy Converter

The THEAC-25, developed by SoundEnergy functions as a central cooling unit in your cooling application.
Its core function is converting heat into cold via thermoacoustic technology. Feeding heat input into one side of the THEAC-25 results into 25 kW – 40 kW cold output  enabling the production of cold air or cold water. The cold output of our technology can reach temperatures as low as -25°C.

A 10 kW unit is in the last stages of development, as well as a 120 – 170 kW device that can be stacked for MW capacities.

No toxic refrigerants or chemicals

Maintenance free

No mechanical moving parts


From Watts to Megawatts

Simple construction

Large freedom of implementation


No chemical fluids

Traditional air conditioning systems use chemical fluids that are highly damaging to the environment.
The THEAC-25 is built with sophisticated technology and does not use any chemicals. The working gas in the THEAC-25 is Argon which is the third most abundant gas in our atmosphere, about 0.94% of our atmosphere consists of Argon. And most important: Argon has zero global warming potential (GWP=0).

The output of the THEAC-25 can reach temparatures below -25ºC.

Clean and sustainable technology

The THEAC-25 operates without any mechanical moving parts, precious metals or materials. The system is maintenance free, needs only a yearly inspection and has an estimated service life up to 30 years.
The operating pressure inside the THEAC-25 is 12 bar. This is comparable to gas cylinders and LPG-tanks in cars. The construction of the THEAC-25 complies to the EU’s Pressure Equipment Directive (PED) and is Lloyd’s certified. And CE marked with ASME certification on its way.
