Spare parts Webasto AT3500 Temperature Limiter Bag

Details

The Webasto 1322831A (also known as 1319798A or 97265A) is a high-quality Overheat Protection Temperature Limiter specifically designed for Webasto Air Top 3500 and Air Top 5000 diesel air heaters. This safety-critical component acts as an automatic thermal cut-out that monitors the temperature of the heat exchanger. If the unit detects temperatures exceeding approximately 150 degrees Celsius, it triggers a safety shutdown by disconnecting the power to the fuel dosing pump and initiating a cooling purge. This process prevents permanent damage to the heater and ensures the safety of the vehicle or vessel. As a genuine Webasto spare part, it is engineered for precise fitment and reliable performance in demanding environments, including marine and commercial vehicle applications. The sensor is typically installed directly onto the heat exchanger with a touch element to ensure accurate thermal readings.
