What is a Finned Tubular Heater?
A finned tubular heater, also known as a finned electric heating tube, features metal fins wrapped around the surface of a conventional element. This increases the heat dissipation area by 2-3 times compared to conventional elements, meaning the surface power load allowed by finned elements is 3-4 times that of conventional elements. The shortened element length reduces heat loss, resulting in rapid heating, uniform heat generation, excellent heat dissipation, high thermal efficiency, long service life, compact size, and low cost, all at the same power level. Designed to meet user requirements, it facilitates installation.

Finned electric heating tubes are available in straight, U-shaped, multiple U-shaped, and curved configurations. Materials include stainless steels such as SUS304, SUS321, and SUS316L. Operating temperatures range from low to medium temperatures (≤350°C) to high temperatures (>700°C). Supporting voltages from 12-660V, single-shot power ranges from 50W to 9kW, and can be installed via flanges or threads to accommodate various pipe sizes. Featuring fast heating, high thermal efficiency, and compact size, they are suitable for air heating, chemical material heating, crude oil heating, and explosion-proof environments.
Datang finned electric heating tubes are ISO9001 certified and offer customized solutions based on media type and power requirements.
Finned Tubular Heater Applications
Finned Tubular Heaters are widely used in industries such as machinery manufacturing, automotive, textiles, food, and air curtain systems for air conditioning.
1. In the chemical industry, finned electric heating tubes are used for heating chemical materials, drying powders under pressure, chemical processes, and spray drying.
2. Heating hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, and paraffin.
3. Heating fluids requiring heating, such as process water, superheated steam, molten salt, nitrogen (air), and water gas.
4. Due to its advanced explosion-proof structure, finned heating tubes are widely used in explosion-proof environments such as the chemical industry, military industry, petroleum, natural gas, offshore platforms, ships, and mining areas.
They are widely used in the machinery manufacturing, automotive, textile, food, and home appliance industries, particularly in air conditioner air curtains. Finned heating tubes are particularly adept at heating petroleum and fuel oil. They are widely used in both industrial and chemical industries.
