chillii Technology

Vision and Know-how of Solar Next AG

SolarNext AG was founded in 2000 to become active in the field of renewable energies and energy efficiency.

Since 2005, SolarNext AG has focused on sorption refrigeration and evolved to a specialist for system solutions in the area of ​​regenerative heating and cooling supply.

The core business of SolarNext AG is the development and sale of standardized chillii® Cooling Kits from 10 kW up to 4 MW (per module). We plan individual thermally driven cooling systems for private, commercial and industrial applications. The product portfolio includes adsorption and absorption refrigeration systems as well as an integrated system controller for controlling the entire system.

Our sorption systems can also be used as heat pumps, e.g. be used in the field of geothermal energy for the provision of district heating.


The key to success of our company is a top-level and interdisciplinary team. As an internationally operating company, we have successfully implemented thermal cooling projects for our customers worldwide.
