1920 1920: Foundation
of GEA in
Bochum by Otto
Happel.
2010: Reorganization
of the group.
Reorganization of
GEA's 9 Divisions into
technologically distinct
Segments. The
largest segment is the
Heat Exchangers
Segment (HX). 2010 2014 2014: In October,
GEA Group
concludes
the agreement on
the sale of the Heat
Exchangers
Segment to Triton.
2015: With the new name,
the former GEA Heat
Exchangers has been formally
split from the GEA Group and is
writing its own history as
Kelvion.


The name Kelvion pays
homage to Lord Kelvin (1824 -
1907). Lord Kelvin formulated
the laws of thermodynamics
and absolute units of
temperature are stated in
kelvin, in his honor.
2016: Being the global
experts in heat
exchange, Kelvion is
ready to guarantee the
best solutions for any
challenge in the different
industrial markets.
