Suggestions on cold zone of electric tubular heater:

Customers often ask us why the service life of the electric tubular heater is very short. In fact, we have to see many reasons for the length of the service life. The quality of the electric tubular heater produced by the manufacturer is on the one hand, and the working environment of the electric tubular heater. In the use of the electric tubular heater, heating liquid is very common. Many heating pipes for heating liquid will also burst. What is the reason for this. In fact, in addition to the quality of the electric heating tube itself, the cold area of the electric heating tube also needs to pay attention to. This is often the matter of the manufacturer, and the general customers have requirements. The establishment of the cold zone is to prevent dry burning of the heating pipe which does not contact with the liquid. Once the stainless steel electric heating pipe heated by liquid appears dry burning, the pipe is easy to burst, which needs attention of customers. Our salesmen also need to pay attention when communicating with customers.
