Flooded Steam-to-Water Vertical Heat Exchanger

- A flooded steam-to-water heat exchanger … uses a new, efficient technology to optimize the net output energy produced from steam, which is a different approach than conventional shell-and-tube heat exchangers.

- By modulating the condensate, the flooded vertical heat exchanger varies the exchange surface.

- The energy input of the flooded vertical heat exchanger is 85% of the conventional heat exchanger for the same net energy produced.

- The exchanger has a stable temperature set-point by modulating the condensate, not the steam.

For building heat or domestic single wall
steam in the tubes

steam in the shell

For domestic double wall steam in the shell
