"Environmentally Resistant Double Glass Tube Type Hot Air Heater" DGH-140X6
Heat-tech - "Double-walled glass tube type hot air heater for environmental resistance" DGH-140X6
Since it does not emit dust from the heating element, it is ideal for use in clean rooms.
The DGH series has both the heating element and the thermocouple sealed in a quartz glass capsule. Therefore, the heating element and the thermocouple do not come into direct contact with the heated gas, preventing dust from oxides generated by these components from contaminating the heated gas. Although the outer diameter is small, it can heat the passing gas to approximately 550°C. Since it does not generate dust from the heating element, it is ideal for use in clean rooms. Six heating elements are incorporated into a metal tube case with a diameter of φ101.6. The large tube diameter reduces pressure loss. Please consider it when a gas flow rate of 800 liters/min is required. Using the thermocouple at the outlet, accurate temperature control can be performed. The tip has internal threads, allowing various fittings to be attached. The DGH-140X6 can accommodate a terminal box. For safety and health measures, the temperature of the heating element can be monitored to prevent overheating.

Detailed information
-
Drying of Silicon Wafers Issues The conventional method was problematic because the drying air contained metal ions. ⇒ Improvement Points Heated and dried using a cleanroom specification hot air heater. Since the heater is glass-coated, the content of metal ions has been reduced.
-
Heat source for the measurement system of silicon wafers Issues There was no good method to easily heat silicon wafers, which was problematic. ⇒ Improvement points High-temperature nitrogen gas was injected using a hot air heater, raising the top surface temperature to 400°C. It became possible to measure the wafers without the need for a vacuum.
-
Nitrogen Drying of Silicon Wafers Issues Natural drying left water spots that were concerning. ⇒ Improvement Points Heated nitrogen was used for drying with a hot air heater. Water spots were eliminated, and there was no oxidation, resulting in improved quality.
