●Feature of the Clean-room & Semiconductor Air Blow Heater DGH-19NM
The DGH series heating element and sensor are also sealed in a capsule of quartz glass.
Neither the heating element nor the sensor in direct contact with the heated gas.
For the reason, dust, such as oxide generated from these not mixed into the heated gas.
In addition, because the gas passes through between the double glass tube, it can also be used to heat the corrosive gas.
The outer diameter is small, but, it can heating passage gas to approximately 550 ℃
- Since the DGH-19NM does not emit dust from the heating element, it is most suitable for use in a clean room
- A heating element of 150w-300w was included in a metal pipe case of φ 19.
- When 15 – 30ℓ/min is necessary, air flow quantity, please adopt it.
- Accurate temperature control can be performed using the thermocouple of the output port.
- The DGH-19NM has screw thread to the output mouth. It can install many accessories .
- The DGH-19NM series can watch heating element temperature by safe measures for prevent overheat.
