What is Finned Tubular Heaters?
Finned Tubular Heaters are manufactured with the same rugged construction as our standard Tubular Heaters and then a helically wound fin is attached to the outer sheath. The fins are fully brazed to the heater sheath for optimum heat dissipation and efficiency. These heaters are ideal for heating air and select gases in forced and natural convection applications.
Finned Tubular Heaters Features
- Steel sheath models are suitable for operating temperatures to 800 °F (427 C)
- Stainless steel sheath models are suitable for operating temperatures to 1200 °F (649 C)
- Premium grade magnesium oxide insulation imbeds the resistance wire coil for optimum heat transfer
- High temperature nickel chromium resistance wire
- Full brazed wound fin: 1 1/8″ diameter x 4.5 fins/inch
- Standard sheath diameter of .440″
- Screw and nut terminals on catalog models
- Many catalog wattage, voltage, and lengths
- Standard and custom options available
- Several models offered with mounting fittings

Finned Tubular Heaters By Industy
Electric finned tube heaters are widely used in workshops such as textile and machinery processing plants as air heaters, for auxiliary heating in gas turbine waste heat boilers or preheating in nuclear power plant seawater cooling systems, for anti-freezing heating of crude oil pipelines, temperature control of chemical reactors, and preheating of exhaust gas treatment devices. They can also be used for pasteurization of dairy products, cooling of freeze-drying equipment for pharmaceuticals, and rapid heating of large venues (such as stadiums and workshops).

Advantages of Choosing Stainless Steel for Finned Tubular Heaters
304 stainless steel is suitable for general heating applications, 316 stainless steel offers resistance to weak acids and bases, and 303 stainless steel is used for high-finish components. Use requires a non-corrosive medium, regular removal of scale buildup, and implementation of anti-freezing measures.
The manufacturing process must meet standards including power deviation testing, leak testing, and a 3000-hour lifespan test to ensure temperature resistance, corrosion resistance, and safety and stability.

Finned Tubular Heaters Application

The spiral fin tube radiator for vegetable and flower greenhouse is an efficient and durable heating equipment, especially suitable for greenhouse cultivation in cold seasons.

During the breeding and brooding process, the high-frequency welded fin tube radiator improves the heat exchange efficiency by increasing the heat dissipation area, and can raise the temperature in the brooding house to the required level in a short time. This design enables the farm to quickly reach and maintain a suitable temperature range (15-20 degrees Celsius) when heating in winter.

Hot-dip galvanized spiral wound fin tube for greenhouse heating, as a key component of the heating system, can efficiently and evenly transfer heat to keep the temperature in the greenhouse within a suitable range

The W-shaped stainless steel finned electric heating tube is an industrial heating element that combines a W-shaped bending structure, a stainless steel casing, and a finned design for efficient electrical energy conversion. Its core structure includes a stainless steel sheath, an internal heating alloy wire (such as nickel-chromium or iron-chromium alloy), and crystalline magnesium oxide powder filled in the gaps to ensure good thermal conductivity and insulation; the fins are usually wrapped around the tube surface to increase the heat exchange area, while the W-shaped (or M-shaped) structure optimizes space utilization and heat distribution uniformity through its bending design.
