HeatExchangers

For the whole portfolio of KODAsteam turbines.

Characteristics Design of the most recent heat exchangers

are based on thermodynamic computationsaccording to our own SW, as well asworldwide accepted standards in the heatexchanging field e.g. HEI Standard andstandards for pressure equipment

e.g. ASME Code, AD Merkblatt The most sophisticated heat exchangercomponents are manuacturedrom alloys and titanium materials
