In the year 1982 Dr. Juan Bassols started with the development of an Ammonia-Resoption-Heatpump. After the first energy crisis the expectations were that heat pumps would replace the conventional gas boilers for heating purpose. After 10 years of development and several prototypes, the first high efficiency GAX-Absorption-Heatpump was installed in 1991. In 1992 Dr. Juan Bassols founded together with some former colleagues the company Colibri in the Netherlands which focus on the development and distribution of Ammonia-Absorption-Refrigeration-Plants. Till the year 2018 they installed around 80 MW of cooling capacity worldwide.
In the year 2019 the company BL thermodynamics was founded in Aachen with the commitment to improve the ammonia absorption technology and provide an important contribution to the actual energy transition.
