Glass tube heater

High-Quality Glass Tube Heater for Refrigerators

Electric heater components are the type of tube heater. Refrigerator defrost is the model number. Heating and drying are the applications of glass tube heaters. White reflection, gold coat, and clear coating are used. The common dimensions are 100mm-3000mm. Power ranges from 120w to 6000w.

The current is 120 volts. 220v,240v,315v,380v,480v. Tube heaters are made from materials such as quartz glass. The filament is made of tungsten, carbon fiber, and nickel-chromium. The dimensions are 10mm-20mm/11x23mm/15x33mm.

Refrigerator Defrost Heaters

The surface is composed of quartz glass, while the look is made of nanocrystal glass. This is a novel refrigerator glass warmer. Furthermore, this is a completely new updated version of the standard tube heater that will be used to heat a high-temperature oven.

In the dry season, refrigerator defrosts heaters are commonly utilized in freezers and refrigerators. It is required for defrosting and preheating. When the heater reaches the chosen temperature, it will turn off automatically.

The glass tube is composed of high-quality, food-grade silicone. With strong temperature resistance, no surface damage, and long service life. At the same time, this is a completely new and improved thermoplastic heater.

The electric blanket features a built-in motor that allows the equipment to be controlled with one hand. The temperature control component is an excellent alternative for heating, cooling, and other sectors that require high heat dissipation components.


It is coiled like a spring strip with resistance wire, inserted into a glass tube with heat-resistant material on both sides, and connect with lead wire to the resistance wire in the head.


Quartz glass tube heaters are most often seen in refrigerators and microwave ovens. Catalysis deodorizing glass tube heater connected distinctive odor will be catalyzed and oxidized to carbon dioxide and water, resulting in the deodorization effect.
