Auxiliary electric heater for the air duct of the wind cabinet

The electric heater of the wind cabinet is mainly used for heating the air in the air duct. It is standardized into three methods: low temperature, medium temperature, and high temperature. The common structural feature is the use of steel plates to support the electric heating pipe to reduce its oscillation. The junction box is equipped with overtemperature control equipment. In addition to being equipped with overtemperature maintenance, it is also necessary to install intermodal equipment between the fan and the heater to ensure that the electric heater starts. After the fan starts, it is necessary to add a differential pressure device before and after the heater to prevent fan malfunctions. The gas pressure heated by the channel heater should generally not exceed 0.3Kg/cm2. If the above pressure needs to be exceeded, please choose a circulating electric heater; The maximum temperature for gas heating in low-temperature heaters shall not exceed 160 ℃; Medium temperature type does not exceed 260 ℃; High temperature type does not exceed 500 ℃.

Features of the electric heater for the wind cabinet:

1. It can heat the air to a very high temperature, up to 450 ℃, and the shell temperature is only around 50 ℃.

2. High efficiency: up to 0.9 or above.

3. The heating and cooling rate block can reach 10 ℃/S, and the adjustment is fast and stable. It will not exhibit the phenomenon of controlled air temperature leading or lagging, causing temperature control drift and uncertainty, making it very suitable for active control.

4. Good mechanical performance: Due to its specially made alloy material as the heating element, it has better mechanical properties and strength than any heating element under the impact of high-pressure air flow. This is more advantageous for systems and accessory experiments that require long-term continuous air heating.

5. Durable, with a lifespan of up to ten years under strict adherence to usage regulations.

6. The air is clean and environmentally friendly.

7. Multiple types of air electric heaters can be customized according to the actual needs of users and provide design solutions.

The electric air heater is primarily used to heat the required air flow from the initial temperature to the desired air temperature, with a maximum of 650 ℃. It has been widely used in drying tunnels, drying rooms, aging rooms, high-temperature rooms, etc,. Especially suitable for active temperature control and large flow high-temperature heaters. The application scale of air electric heaters is wide: they can heat any gas, and the generated hot air is dry, non conductive, non incinerable, non explosive, non chemically corrosive, pollution-free, safe and reliable, and the heated space heats up quickly (controllable).

Specification model

The single unit power ranges from 2KW to 500KW series.

Notice:

In terms of operation, it is necessary to add a linkage device between the fan and the heater to ensure that the heater starts, which needs to be carried out after the fan starts. After the heater stops working, it is necessary to delay the operation of the fan for more than 3 minutes to prevent damage caused by overheating of the heater. It is necessary to comply with NEC specifications in terms of single circuit wiring, and each branch current must not exceed 48A. The gas pressure heated by the channel heater generally does not exceed 0.3kg/cm2. If you want to exceed the above pressure specifications, please choose a circulating heater. The maximum temperature for gas heating in low-temperature heaters shall not exceed 160 ℃; The medium temperature type shall not exceed 260 ℃, and the high temperature type shall not exceed 500 ℃.
