The performance characteristics and functions of tubular heaters?

Coaxial heaters are the most typical structure of resistance heaters, with the most product categories and the most widely used ones. Its application fields include catering equipment, laundry equipment, heating equipment and refrigeration equipment.


The shell of the sensor is made of corrosion-resistant stainless steel to ensure that the device can be used continuously and stably. The material of the resistance wire is made of FeCrAl or NiCr alloy magnesium oxide powder, which is densely filled between the shell and the resistance wire, and has the effect of insulation and resonance. The lead-out rod connects the resistance wire and the external circuit. Has good high temperature resistance, mechanical properties and welding performance.


In actual use, the duct heater needs to be bent to meet the application requirements. Catheter heaters can be divided into two types: air use and liquid use. For catheter heaters used in liquids, it is necessary to perform surface coating treatment on the tube shell to prevent scale, and also need to install fuses to ensure the safety of the device.
