The new Santi 303 Thermovalve has a 270 degree 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, which allows for trouble-free connection of the hopper cable both in the position of the connector to the right and left.

Until now, when using a "standard" thermovalve, whose rotation range is only 90 degrees, with its trouble-free use by backmount divers, used by sidemount divers, unfortunately, 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.

Thermovalve 303 is the transition between the external battery and the elements of the heating system located under the drysuit. It  replaces the standard inlet valve, as unlike a connector, it has two functions at the same time, an inlet valve and an integrated connector.

SANTI Heating Systems Explained

The low profile SANTI Thermovalve fully replaces the dry suit inflator valve cabling in power to connect to heating systems including heated undersuits, vests and gloves. The SANTI dry suit Connector on the other hand needs to be used together with your existing inflator valve with the valve removed so the connector is sitting against the dry suit then screwed back on top. For either system to work, a diver needs an external power supply. SANTI supplies  6 and 24aH batteries which give different runtimes depending on the heating system a diver is wearing.
