What is Spiral Heaters?

Spiral heaters are a type of resistor used for electric heating purposes. Resistors are electrical resistors that convert electrical energy into heat energy. Spiral heaters are typically created by winding a wire (usually a high-resistance material such as nickel-chromium alloy) in a specific pattern, often placed inside a pipe.


Types of Spiral Heaters

  1. Straight Spiral Heaters: These types of heaters are typically used on flat pipes or surfaces. The heating element is wound in a straight pattern and has a flat shape.
  2. Cylindrical Spiral Heaters: Cylindrical heaters are used in tubular containers or cylindrical structures. The spiral wire is wound according to the cylindrical surface, providing heating in this manner.
  3. Long Spiral Heaters: Long spiral heaters are commonly used in large-volume heating systems such as industrial ovens. A long wire is wound in a spiral shape and spread over a long area to provide homogeneous heating.
  4. Compact Spiral Heaters: These heaters are designed for use in smaller spaces. Compact heaters made with tighter spiral winding allow for high heat production in limited spaces.
  5. Digital Controlled Spiral Heaters: These heaters, equipped with advanced technology, have the ability to digitally control temperature and power levels, providing more precise temperature control.
  6. Stainless Steel Spiral Heaters: Stainless steel spiral heaters, used in industrial or hygienic applications, are resistant to corrosion and easy to clean.

Technical Details for Selecting Spiral Heaters

  1. Power (Watt)

    Determining the appropriate power level depending on the size of the heating environment and heating requirements is important. Inadequate power may result in failure to achieve the desired temperature.

  2. Voltage

    The voltage of the electrical system to be used must be compatible with the voltage of the spiral heater. Voltage mismatch can negatively affect the performance of the heater and pose a safety risk.

  3. Temperature Range

    The operating temperature range of the spiral heater should be suitable for the application's requirements. An appropriate range should be selected, especially for high or low-temperature applications.

  4. Body Material

    The body material of the heater should be resistant to heat and environmental conditions. Corrosion-resistant materials like stainless steel may be preferred.

  5. Heating Element Material

    The material of the heating element should be resistant to high temperatures and have a long lifespan. Materials like nickel-chromium alloy are commonly preferred.

  6. Mounting Type

    The mounting type of the spiral heater should be selected based on the application environment and ease of use. Different mounting types such as clamp connection, flange connection, or cable connection may be available.

  7. Application Area

    The characteristics of the environment where the spiral heater will be used (humidity, chemicals, pressure, etc.) should be considered. These factors should be taken into account in material selection and technical specifications.

  8. Control and Safety Features

    Digital control features, overheat protection, and overcurrent protection, among other safety features, play an important role in selecting spiral heaters.
