What are band heaters used for?
Band heaters are commonly used whenever heat is needed around the surface area of a pipe, tube or cylindrical vessel. They provide a fast-acting indirect heat that many industries, especially plastics, find perfect for their needs. There are three main types of band heaters: mica, ceramic and mineral-insulated.
What is a band heater?
Band heaters are used to heat pipes, nozzles, barrels, and other cylindrical parts. These fast-heat band heaters electrically warm the external surface of a cylindrical part to provide indirect heating. They have mica or ceramic insulation that helps ensure high dielectric strength and effective heat transfer.
How hot do cartridge heaters get?
High temperature cartridge heaters are made for high temperature applications with temperatures that range between 1400° F or 760° C up to 1600° F or 870° C. Most high temperature cartridge heaters are swagged to maximize heat transfer and vibration resistance.
What is nozzle heater?
AccuTherm Nozzle Heater This process involves heat which is essential for liquefying and melting metal. The magnesium oxide is selected to high quality standards to provide optimum compaction and maximum electrical resistant properties that are supported by sufficient heat transfer characteristics.
How do induction heaters work?
An induction heater consists of an electromagnet and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The rapidly alternating magnetic field penetrates the object, generating electric currents inside the conductor, called eddy currents.
How do I calculate the wattage of my heater?
How to Calculate Heater Wattage
- Measure the length and width of the room and multiply the two measurements to determine the square footage.
- Multiply the number of square feet by 10 watts.
- Add the square footage of all the rooms that you want heated at the same time.
What is a mica strip?
Mica Strip Heaters are versatile, efficient and economical. They are of the same construction as the mica band heater in a flat design. The mica strip heaters furnish even heat distribution for use in hot plates, sealing equipment, hot stamping, dies, and molds with sheath temperatures up to 800°F (425°C).
Are cartridge heaters AC or DC?
The cartridge heater needs to receive AC power to work, most of the outputs on SSR’s that I’ve seen are DC. AC to PID to DC might be the most straightforward.
How do I choose a cartridge heater?
How to choose a cartridge heater?
- Determine the Gap. The gap is the difference between the minimum diameter of the heater and the maximum diameter of the hole.
- Determine the Watt Density. Watt density is the heat flow rate or surface loading.
- Power=Watt density(W/cm²)*Heat section(cm)*Norminal heater dia*3.1416.
What materials can be used for induction heating?
The material used to make the work piece can be a metal such as copper, aluminum, steel, or brass. It can also be a semiconductor such as graphite, carbon or silicon carbide.
What is a band heater used for?
Pipe heating, drum heating, barrel heating normally used for oils, lubricants or any other circular applications. Band heaters use electric heating elements (NiCr wire) to heat-up the external surface of drums or pipes for a gradual heat transfer.
What is mica band heater?
Mica band heaters are an inexpensive industrial heating solution that surrounds pipes and tubes that require external indirect heating. Pipe heating, drum heating, barrel heating normally used for oils, lubricants or any other circular applications.
What types of band heaters are available at wattco?
The various types of band heaters available at WATTCO include mica insulated band heaters and ceramic band heaters. For direct heating, our immersion heaters section is suggested as a more efficient means for heating your liquids. Direct heating uses flanged heaters, screw plug heaters, over the side heaters as well as pipe heaters
What is a nozzle band heater used for?
Highly recommended for heating applications where premature nozzle band heater burn-out on plastic injection molding machines is a constant problem due to contamination from plastic overflow or other contaminants. They are proven to be very effective for processing Teflon® and high temperature resins.
