Spiral Heat Exchanger

The spiral heat exchanger was developed in the 1920s for use in the paper industry by the Swedish engineer Curt Rosenblad. For the first time, a heat exchanger was available that allowed troublefree heat transfer between particle-loaded process streams.

In the early 1970s, Tranter HES predecessor Kapp Apparatebau started manufacturing spiral heat exchangers based on an original design with distinct advantages over the Rosenblad design. Today, Tranter HES is the only company capable of manufacturing spiral heat exchangers either in its own design or in the Rosenblad design, in almost any size from any cold-workable and weldable material. This engineering and manufacturing flexibility enables us to offer replacements units for all applications without the need for costly repiping.
