Air duct electric heater
Functional Characteristics Specification Parameter
  • 1, the air can be heated to a very high temperature, up to 450 ° C, the shell temperature is only about 50 ° C.
    2, high efficiency: up to 0.9 or more.
    3, heating and cooling rate block, up to 10 ° C / S, fast and stable adjustment. There is no leading air temperature lead and hysteresis, which makes the temperature control drift, which is suitable for automatic control.
    4, good mechanical properties: because its heating element is a special alloy material, so under the impact of high-pressure air flow, it is better than any heating body mechanical properties and strength, which is necessary for a long time continuous air heating System and accessory testing is even more advantageous.
    5, durable, in strict compliance with the use of the rules, the life span of up to ten years.
    6, the air is clean, environmentally friendly.
    7. According to the actual needs of users, we can provide design schemes and customize multi-type air electric heaters.
  • Rated voltage：220V、380V
    Explosion-proof grade：ExdⅡBT1-4
    Temperature control method：Automatic temperature control
    Temperature control accuracy：±1℃
The air duct type electric heater is mainly used for air heating in the air duct. The specifications are divided into three types: low temperature, medium temperature and high temperature. The junction box is equipped with an over temperature control device. In addition to the control, in addition to the over-temperature protection, an intermodal device is installed between the fan and the heater to ensure that the electric heater must be started after the fan is started, and a differential pressure device is added before and after the heater to prevent the fan from being blown. Fault, the gas pressure of the channel heater should not exceed 0.3Kg/cm2. If it is necessary to exceed the above pressure, please use the circulating electric heater; the low temperature heater gas heating maximum temperature does not exceed 160 °C; the medium temperature type does not exceed 260 °C; high temperature type does not exceed 500 °C.
