Quartz heating coil

model SH-DRQ401

describe

The far-infrared nano energy-saving quartz heating coil is selected from far-infrared quartz radiant tube, which has good performance in absorbing infrared light, and the temperature of the tube wall rises rapidly; high-temperature heat insulation layer is adopted to keep the surface temperature of the heater below 100℃, and only a small part of the heat is transferred To the air, it fully utilizes the heat energy converted from electric energy, and at the same time it plays a role in reducing the temperature of the workshop. It has the advantages of high temperature, long life, energy saving, etc.; the use of high temperature resistant ceramics, high temperature resistance, good insulation performance, while tightening the quartz radiant tube to improve safety performance. It is widely used in pelletizers, wire drawing machines, chemical fiber, engineering plastics, plastic machinery, electronics, medicine, food and various pipeline heating.
