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 passes en 250 cold water tests<\/p>\n
First & Second Stage Regulators<\/p>\n
CERTIFICATION EN 250\/2014 FOR COLD WATER.
\nTHEE 1ST STAGE IS ENVIRONMENTALLY SEALED, PROTECTING IT AGAINST ICING IN COLD WATER AND AGAINST CONTAMINATION FROM PARTICULATE MATTER IN SILTY CONDITIONS. WHEN PAIRED WITH THE MASTER SECOND STAGE, WHICH INCLUDES AN INTERNAL HEAT EXCHANGER, THIS REGULATOR IS AN EXCELLENT CHOICE FOR DIVERS EXPLORING THE MOST EXTREME COLD WATER ENVIRONMENTS.<\/p>\n","protected":false},"excerpt":{"rendered":"
