Santi 303 Thermovalve

We have been waiting for this day! We are glad to introduce a new, innovative SANTI 303 Thermovalve.  The thermovalve is the transition between the external battery and the elements of the heating system located under the drysuit. The Thermovalve replaces the standard inlet valve, and unlike a connector, it has two functions at the same time, an inlet valve and an integrated connector.


The new SANTI 303 Thermovalve has a rotating head, which is an innovative solution in thermovalve design technology. Its great advantage is placing the cable with the E / O connector in the down position, with the possibility of turning the head by 270 degrees. This  allows for trouble-free connection of the battery cable both in the position of the connector to the right and left. Until now, when using a “standard” thermo-valve, whose rotation range is only 90 degrees.  When it is used by sidemount divers it is necessary to point the power cable upwards in order to allow the positioning of the valve spigot to the right side. The swivel range completely eliminates such situations, so the new thermovalve can be called an extremely universal design in its application.

The SANTI 303 Thermovalve works with the Santi Heated BZ400 and Flex 2.0. undergarments.
