Santi Thermovalve 303

Santi Thermovalve 303 – Advanced Heating and Inflation

The Santi Thermovalve 303 features a unique 270-degree rotating head to improve your diving experience. This innovative design offers a superior solution for both drysuit inflation and integrated heating power. 

Unlike a Drysuit Connector, this low-profile unit fully replaces your existing drysuit inflator valve. Consequently, it streamlines your gear by combining two essential functions into one robust component. Built-in cabling connects directly to Santi heating systems, including heated undersuits, vests, and gloves.

Optimal Cable Routing and Flexibility

A significant advantage of the Thermovalve 303 is the clever placement of the E/O connector cable. By positioning the cable in the down position, the valve head can turn freely by 270 degrees. This rotation allows for a trouble-free connection in both the right and left positions. 

Therefore, you can customise your technical diving setup to suit your specific hose-routing preferences. This flexibility ensures that your external battery cable remains secure and out of the way during complex dives.

Technical Compatibility and Integration

The Santi drysuit valve for heating works with any power supply up to 12V. It features two electrical connectors on opposite sides of the cable for seamless integration. One side provides a standard e/o connection for your battery, while the other links to your heated garment. 

Furthermore, the total cable length is approximately 55cm, providing ample reach inside your suit. Santi offers this valve in both Apeks and Si-Tech screw sizes to fit most drysuit brands.
