    Features/Applications

    Features

    • Compact design

      Can be installed in small spaces.

    • No steam leaks

      Operates below saturation temperature, resulting in no steam leaks and great energy saving performance.

    • Easy maintenance

      Less components make maintenance and inspection easy.

    Typical applications

    Suitable for foodstuff devices, bio devices, compact heat exchangers, tank heating, main heat pipes, steam tracing, cleaning devices, and other such applications.
