It is comprised of horizontal helical coils, and is of water-tube design. It is produced for steam capacities in the 150–4,000 kg/h range. Since the condensate tank can be installed on top of the steam generator, the latter takes up almost as much space as a vertical steam generator. The flue outlet can be positioned from the top or from behind, which facilitates the installation.

While the efficiency can be increased to 95% with a non-condensing economizer, 98% efficiency can be achieved with a condensing one. If desired, steam generators can be produced as a package with a water treatment system. These generators have no risk of explosion and may legally be placed in residential areas. When the system is first operated, it takes at most 4–5 minutes to generate steam. This way, depending on the number of operating days per year, in contrast to steam boilers—in terms of initial investment costs—the steam generator burns approximately 10–35% less fuel.

Regarding steam production, thanks to its team and expertise, Jenesis is the only high-tech company in Turkey capable of producing steam generators that can produce, at constant operating pressure, high-quality, dry steam, even at peak load demands.
