Using natural refrigerants, such as water, protect the environment and climate.

STAC Technology is an R&D Engineering company focused on developing compressors using water as the process driver and the refrigerant. 

STAC's compressors are used in its own developed chillers making chilled water or ice slurry in the district energy industry (heating and cooling) 

STACs mission is to disrupt the District Heating and Cooling industry to use water as the process driver and the refrigerant in new innovative solutions.

 STAC is focused on making it possible before 2030 for citizens in private and residential buildings to be able to make comfort heating, and comfort cooling themselves.

STAC's vapor compression system innovation lies in its compact state-of-the-art turbo-compressor, able to generate both low-pressure chilled water and ice slurry, depending on key system parameters and the direction of the energy cycle.  

When there is low cooling demand, the excess capacity is directed into a storage system of ice slurry or fresh water. When cooling demand is at

it's peak, the ice surplus is drained from its storage. 

 STACs vapor compression system can operate continuously (24/7), harnessing untapped thermal energy from water bodies, i.e., the ocean, lakes, rivers, excess industrial heat, solar thermal and geothermal, and district heating (DH) grids.

STACs Pilot Chiller Plant is designed to showcase our sustainable zero emission technology in multiple applications across various industries and buildings with a need for cooling in the form of chilled water or ice slurry. 

STACs vapor compression system unlocks significant energy and CO2 reductions compared to ammonia absorption systems and other conventional cooling solutions, having precise applications in space cooling of industrial, commercial, and residential applications.
