Air duct electric heaters are mainly used for heating air in air ducts

The air duct electric heater is mainly used for heating the air in the air duct, with specifications divided into three forms: low temperature, medium temperature, and high temperature. The common feature in the structure is that it uses steel plates to support the electric heating tube to reduce the vibration of the electric heating tube when the fan stops, and an over temperature control device is installed in the junction box. The low-temperature type can be directly installed on the air duct, while the medium temperature and high-temperature types have 100mm thick insulation material sandwiched between the outer wall of the channel and the heater junction box due to structural differences. This reduces the external heat dissipation of the entire channel and also reduces the temperature inside the junction box.

The circulating air duct heater is mainly used for heating the air in the air duct. The specifications of the circulating air duct heater are divided into three forms: low temperature, medium temperature, and high temperature. The common structural feature of the circulating air duct heater is that it uses steel plates to support the circulating air duct heater to reduce the vibration of the circulating air duct heater when the fan stops. The low temperature type can be directly installed on the circulating air duct heater, while the medium temperature and high temperature types have insulation materials sandwiched between the outer wall of the channel and the heater junction box, which reduces the external heat dissipation of the entire circulating air duct heater channel and the temperature inside the junction chamber.

Structure of circulating air duct heater:

1. The circulating air duct heater uses stainless steel heating tubes as the heating element;

2. The circulating air duct heater is supported by carbon steel or stainless steel materials;

3. The circulating air duct heater is composed of a combination connection method.

Characteristics of circulating air duct heater:

1. The circulating air duct heater adopts an externally wound corrugated stainless steel strip, greatly improving the heat exchange efficiency;

2. The design of the circulating air duct heater is reasonable, with low wind resistance and uniform heating;

3. A temperature controller and fuse are installed on the circulating air duct heater, which can be used to control the operation of the circulating air duct heater in case of air temperature exceeding the limit, ensuring a foolproof operation
