2nd STAGE XS COMPACT PRO:

In order to achieve extremely high performance in low temperature environments,
the second stage in particular was designed with the special Thermoconductive Thermoplastic Neopolymer
that has the capacity to transfer heat like a metal while preserving the design flexibility, chemical resistance,
and physical and mechanical properties of a conventional thermoplastic.

That is, it makes it possible to drastically reduce the weight while delivering heat conductivity on a par with metal cases.
Thanks to this material and a specially conceived purge valve, it can pass all the tests for use in cold water with flying colors.
