Products for the highly efficient storage of heat, cold and air.
Our products, from PCM material to system and Special storage, stand for a wide range of applications in refrigeration/air conditioning and heating technology. Bring your system up to date with our macro-encapsulated PCM – easy retrofit of the accumulator via standard socket or flange.
We produce the right storage system for your projects for solar systems, domestic hot water and drinking water systems, buffer and Cold Storage, PV systems or do you even need a Special storage – we have a solution for all applications up to 100,000 l.
Invest sensibly in the future and take advantage of a self-sufficient energy supply with systems from kraftBoxx.
- Our motto: We make ourselves strong - for an energy-neutral and clean future.

Refrigerants and heat transfer media



Our heat transfer fluids, heat transfer media and cooling brines are used in applications where frost and corrosion resistance are system relevant and have high safety requirements.
Application:
in refrigeration and air conditioning systems, solar systems, heating systems, heat pumps and geothermal probes.
The inhibitors reliably protect all materials commonly used in plant engineering against overheating, corrosion and silting.
