Customized 220V 380V Industrial Finned Heating Tube for Air Ducts

Short Description:

Finned electric heating tubes are metal heat sinks wound on the surface of ordinary components. Compared with ordinary components, the heat dissipation area is enlarged, that is, the surface power load allowed by finned components is higher than that of ordinary components. Due to the shortened length of the component, the heat loss itself is reduced. Under the same power conditions, it has the advantages of fast heating, uniform heating, good heat dissipation performance, high thermal efficiency, long service life, small size of heating device, and low cost.

Process: Finned heating tubes are made of fins wrapped around the outer layer of the heating tube to dissipate heat.

Application:

1. Heating of chemical materials in the chemical industry, drying of some powders under a certain pressure, chemical processes and spray drying are all achieved through finned electric heating tubes.

2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin.

3. Heating of fluids that need to be heated, such as process water, superheated steam, molten salt, nitrogen (air), water gas, etc.

4. Since the finned electric heating tube adopts advanced explosion-proof structure, the equipment can be widely used in chemical industry, military industry, petroleum, natural gas, offshore platforms, ships, mining areas and other explosion-proof places.

5. Used for heating of ovens and drying tunnels, the general heating medium is air.

Product details

1. Stainless steel 304 heating tube, temperature resistance of 300-700C, stainless steel material can be selected according to the operating environment temperature, heating medium, etc;

2. Imported magnesium oxide powder is selected, which has the characteristics of high temperature resistance and good insulation performance, making it more reliable to use;

3. High quality electric heating wire is used, which has the characteristics of uniform heat dissipation, high temperature and oxidation resistance, and good elongation performance;

4. Factory direct supply, stable supply, complete specifications, diverse types, and support for non-standard customization;

Working Principle

Finned tubular heaters increase the outer or inner surface area of the heat exchange tube by adding fins to the surface of the heat exchange tube, thereby improving the heat exchange efficiency. This design not only improves the heat transfer efficiency, but also increases the heat dissipation area. Finned tubes are easy to install, reduce the number of connection points, reduce the chance of water leakage, are easy to maintain, and have a long service life.

Product use instructions

★Do not in outdoor environments with high humidity.

★When the dry burning electric heating tube heats the air, the components should be arranged evenly and crisscrossed to ensure that components have good heat dissipation conditions and that the air passing through can be fully heated.

★The default material for stock items is stainless steel 201, the recommended operating temperature is <250°C. Other temperatures and materials can be customized, with stainless steel 304 selected for temperatures below 00°C and stainless steel 310S selected for temperatures below 800°C.
