Industrial tubular heaters tapped for refrigeration defrost application
Discovering the various uses for electric heat is one of the aspects of electric heating elements that always draws the attention of consumers. The controlled heating made possible by industrial tubular heaters is used in a variety of industrial applications. Therefore, this blog post will provide an overview of how industrial tubular heaters are used in the refrigeration industry as well as details about various other information regarding tubular heaters.
The application of electric heat to refrigerator doors is one of the most notable and unique applications we have come across. Industrial tubular heaters can perform the same functions as heat trace cable, which is typically used for defrosting and freeze protection in refrigerator doors. It is possible to design an airflow tunnel inside the door frame and force heated air through it rather than lining the door frame with heat trace cable. Additionally, by applying heat to the refrigerator door edges, you can speed up the defrosting process . It generates a small amount of heat that helps prevent the doors from becoming frozen due to frequent opening and closing. Additionally, the tubular electric heater can also be changed with less effort and time than the heat trace cable in the event of a heater malfunction.
This controlled heating at the borders of refrigeration doors is used in wide range of applications such as food and beverage processing, as well as medical, scientific, and many more.
What are industrial tubular heaters?
Tubular heating elements are well recognized as the basis of all process heating systems. Industrial tubular heaters can be formed into almost any shape and welded to any metal surface to efficiently meet your heating needs. They are available in both single-ended as well as double-ended designs. The double-ended tubular design has terminals at both ends and is much more flexible for bending than the single-ended tubular design, which has both terminals at one end. Tubular heating elements are used in a variety of heating applications requiring process temperatures of up to 700 °C.
They can transfer heat through all three heating modes: conduction, convection, and radiation. We use high-quality magnesium oxide to allow for efficient heat transfer and dielectric strength. They can be banked together to create a larger heating surface and can be installed both vertically and horizontally.
Our tubular heaters are available in lengths starting at 0.6 meters. Bends are made to the specifications of the customer, starting at 9mm in diameter and 45 W/inch2 in watt density to fit a variety of applications. Bending radiuses are calculated using computer software by our expert design team to ensure optimal performance and prevent any heater mishaps. In addition, various diameters, including 8 mm, 11 mm, 12.5, 13.5 mm, and 16 mm, are available based on requirements. To help protect the heater from physical stress, these heating elements can be covered with strong outer sheath of SS 304, 321, 310, 316, Inconel, or Teflon.
Temperature sensors, such as thermostats as well as thermocouples, can be used to control temperature as needed to ensure the precise working of heating elements.
What are the main uses for industrial tubular electric heater?
Industrial tubular heaters are well-known because of their adaptability as well as toughness. The heating elements are typically bent into a U shape. They can practically be configured in the factory to suit a variety of industrial heating applications. Tubular heaters are an reliable options when superior heat transfer is required for applications involving air, heating liquids, or metals. Process fluids like water, chemicals, oil, etc. are heated using tubular electric heaters. They are also designed to come into direct contact with materials to be heated, including liquids, solids, and gases. An immersion heater can be used to heat the process fluid inside the tank. Otherwise, a circulation heater can heat it as it flows. They are significantly used in the chemical as well as oil industries.
However, other common uses of electric tubular heaters include heating by radiation. Tubular heaters can be clamped vertically or horizontally and wall-mounted, allowing them to be used almost anywhere. Furthermore, they enable high dielectric strength as well as even heat distribution. Tubular electric heaters are suitable for almost every industrial heating application, from immersion to air heating.
Because of their versatility, they are used for a wide range of applications, including:
- Tank heating
- Medical and analytical device heating
- Automotive as well as transportation industry
- Food Service Equipment
- Ovens – Process, Curing, Food
- Spas as well as hot tubs
- Textile as well as chemical dryers
- Wax heating
- Welding preheat equipment
- Alkaline cleaning solutions, tars, and asphalt heating
- Paint booth
We also manufacture finned tubular heaters for effective heat transfer. A stable surface temperature for the elements is made possible increased surface area by the fins. To view the various technical specifications, download the datasheet for finned tubular electric heaters.
