1. The electric heating tube adopts outer-wound corrugated stainless steel belt, which increases the heat dissipation area and greatly improves the heat exchange efficiency.
2. The heater has reasonable design, low wind resistance, uniform heating, and no high and low temperature dead angles.
3. Double protection, good safety performance. A thermostat and fuse are installed on the heater, which can be used to control the air temperature of the air duct to work under the condition of over-temperature and no wind to ensure that it is safe.
