Product Details

Jaye Custom Channel Strip Heater is mainly used for air heating in the air duct. The specifications are divided into three types of low temperature, medium temperature and high temperature. The finned electric heating tube structure increases the heat exchange area and greatly improves the heat exchange efficiency. The steel plate is used 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.

It includes an inner metal tube and an outer metal tube on the outside of the inner metal tube. A heating element is arranged between the inner metal tube and the outer metal tube. The heating element is spiral, and the spiral heating element is coiled inside. On the metal tube, the inner wall of the outer metal tube is in contact with the outside of the spiral heating element. With the above technical solution, since the liquid is a spiral channel that is much longer than the straight channel, it greatly increases the contact heat transfer surface area and effectively increases the heat absorption time, so that the fluid is fully heated, and at the same time, by changing the embedded electricity The pitch distribution of the heating element enters the requirements of high power density in the head area and low power density in the tail area.


In terms of control, there must be an interlocking device between the fan and the electric heater to ensure that the electric heater starts

It needs to be carried out after the fan starts work. After the electric heater stops working, the fan must be delayed for more than 3 minutes to prevent the electric heater from overheating and damage. The gas pressure heated by the channel electric heater generally does not exceed 0.3barg. If the pressure exceeds this value, it is recommended to use the circulating electric heater. The maximum temperature of the gas heated by the low-temperature channel electric heater does not exceed 160℃; the maximum temperature of the gas heated by the medium-temperature channel electric heater does not exceed 260℃; the maximum temperature of the gas heated by the high-temperature channel electric heater does not exceed 500℃ .

Scope of application

Mainly used for air heating in the air duct. The specifications are divided into three types: low temperature type, medium temperature type and high temperature type. They all use the structure of steel plate to support the electric heating element to reduce the vibration of the tubular electric heating element when the fan stops. In the junction box All are equipped with over-temperature control devices. The low temperature type can be directly installed on the air duct, while the medium temperature and high temperature type are different in structure. A 100mm thick insulation layer is sandwiched between the outer wall of the air duct and the heater junction box. On the one hand, it can reduce the external heat dissipation of the entire air duct. On the other hand, the temperature in the wiring compartment can also be reduced. Therefore, for the installation of medium and high temperature channel electric heaters, a 100mm mounting frame must be installed on the air duct first. Low and medium temperature channel electric heaters can use finned electric heating elements, and high temperature channel electric heaters can use tubular electric heating elements.
