Baltzar von Platen (1898-1984) together with
Carl Munters[?] was the inventor of the
gas absorption refrigerator[?] in
1922 while they were both
Swedish engineering students at the
Royal Institute of Technology in
Stockholm, Sweden which produced cold from a heat source such as propane, electricity or kerosene. In 1923 production by AB Arctic began. In 1925 AB Arctic was purchased by
Electrolux[?] which began selling them worldwide.
Servel[?] purchased rights to manufacture the refrigerator in
1925 and was the only U.S. manufacturer for many years.
Baltzar von Platen also worked with ASEA[?], Sweden's major electrical company, together with Erik Lundblad[?] on the development of a process which used heat and pressure to produce diamonds. Von Platen had left the project before it succeeded in producing the first synthetic diamonds in 1953.
