风道式加热器主要用于风道中的空气加热，规格分低温、中温、高温三种形式，在结构上的共同之处是采用了用钢板支撑电热管以减少风机停止时电热管的振动，在接线盒中都装有超温控制装置。低温型可直接安装在风道上，而中温型、高温型由于结构上的不同，在通道外壁至加热器接线盒夹有100mm 厚的保温材料，一方面减少整个通道的对外散热，另一方面也减少了接线腔内的温度。

产品特点:
1．电加热管采用外绕波纹式不锈钢带，增加了散热面积，大大提高了热交换效率。
2．加热器设计合理，风阻小，加热均匀，无高、低温死角。
3．双重保护，安全性能好。在加热器上安装了温控器、熔断器，可以用来控制风道空气温度超温和无无风的情况下工作，确保万无一失。

产品应用：
加热空气，用于各种不同物质的干燥/硫化，热处理，再加热和除湿及其他类似应用。

Product Overview:

Duct heaters used in the air duct heating, specifications at low temperature, the temperature, high-temperature three forms, in the common structure is supported by a steel plate used to reduce the electric fan at the end of the electric vibration, In the junction box are equipped with ultra-temperature control devices. Low-temperature-can be installed directly over the wind and temperature in the type of high temperature due to structural differences in access to the outer wall heater junction box folder with 100 mm thick insulation material, on the one hand to reduce the access of external cooling, on the other hand Have reduced wiring cavity temperature.

Features:
1. The use of electric heating-around corrugated stainless steel belt, increasing the cooling area, greatly increasing the heat exchange efficiency.
2. Heater rational design, Drag small, uniform heating, no high, low corner.
3. Dual protection, good safety performance. The heater is installed on temperature control, fuses, can be used to control the wind, the temperature of the air without super-mild calm under the circumstances to ensure foolproof.

Applications:
Heating air, for a variety of different substances drying / curing, heat treatment, re-heating and dehumidification and other similar applications.
