It is coiled as spring strip used resistance wire, inset it into glass tube, the both sides of glass tube are made of heat resistant material, connect lead wire to resistance wire in the head



Quartz glass tube heaters are mainly used in refrigeration and microwave ovens.Catalysis deodorizing glass tube heaterattached peculiar smell will be catalyzed and oxidized to carbon dioxide and water, therefore, get the effect of deodorization.



— RBG1: transparent glass tube— RBG2: deodorization— RBG3: opaque glass tube— RBG4: two-double vacuum glass tube— RBG5: two-double transparent glass tubeThe above are small power ones for defrosting in refrigerator. With the power range 100W~300W, they are airproofed on the ends with rubber.— RBG6: barbecuing tube

The heater is cooking heat source in the microwave oven. Generally 2 pcs as one suite in series and the power of single tube is 400W~600W. Bigger surface load and higher radiating coefficient make the microwave cooking food more quickly.
