The thermal system plays a considerable role in the optimal function of shut-off nozzles. Heating systems contain a heating unit, temperature sensors and the associated controllers.
The heater band should be durable and have sufficient power reserves. The temperature sensors must exhibit a fast response mode and a long service life. The system is determined by ist weakest factor. If a wrong heating system is implemented, this could perform unreliably and impair or detract from the performance of the nozzle substantially.
