The most common way to heat fluids and molds is to use a thermal or industrial element. The thermal element consists of a thin semiconductor wire with high resistance. And this resistance wire is wrapped around a refractory ceramic core, which has the property of heating up and bearing high electric current, and heat is produced when the electric current passes through it. The main material of the elements is nichrome or nickel-chrome and they have different powers. In general, it can be said that a thermal element is a device that converts electrical energy into thermal energy, and due to the production of high heat, it has a very high electrical resistance.
Types of thermal element
Thermal elements are usually used in various industries such as plastic injection, iron smelting industries, etc. One type of thermal element is not used for all industries and there are different types of this part. Among the most widely used types of heating elements are: glass element, ceramic element, rod element, belt element (ring).
Fashengi element
Coil heater element
Flanged element
Pool element
Glass element
Glass elements are usually filled with halogen gas, which can increase the temperature up to 2600 degrees Celsius. This type of heater is used in plastic heating industries, research experiments in thermal deformation and drying devices, as well as radiant heating.
Ceramic element
These types of heaters use ceramic electrical insulation and are mostly made in the form of a ring. Ceramic elements are used in packaging industries, food industries, plastic production industries, production of polyethylene pipes, and production of ceramic tiles. Ceramic elements are divided into different types depending on their application, such as: belt ceramic element, round, The bed and the bed are divided.
Ram element
Rod elements are one of the most widely used elements in industries, which can be ordered and produced in different sizes and are made with copper, titanium steel, etc. coatings depending on the type of performance. This type of heater can be manufactured in different voltages and powers and has different types such as nut, fin and flange. They also have a strong external coating to protect against electrical pressures. Buying a bar element for household appliances, dryers, packaging, cold storage and glass and plastic industries.
Ring element
Ring element or belt or belt that are produced in different sizes and types including framed, wire, screw and simple. And they can be ordered with steel and electrogalvanized covers and different watts. This type of element is used for heat transfer through contact, especially injection cylinders. It is also used in the melting and injection and production and plastic injection industries.
Finish element
Due to the variable diameter, cartridge elements are used in many industries. Due to their coating, they have the ability to work at high thermal power. Other good points of these elements are their controllability by different thermocouples and their ability to be used in tight spaces. Among the uses of these elements, we can mention medical equipment, plastic industries, packaging machines, etc.
Heater Coil Element
The coil heater element can be used in places with limited space and the need for very high heat. Because these elements are able to operate at temperatures higher than 700 degrees Celsius and also have relatively high flexibility. This type of element is used in food industries, packaging machines, cutting machines, plastic industries and creating heat in a vacuum, etc. they use.
Flanged element
This type of heater is used to separate the thermal part and the electrical connection part and install and maintain the element. Flanged elements have the ability to produce very high heat. And in standard models, they use stainless steel rod and forged brass or steel flange. Its uses include: refinery and petrochemical industries, as well as generating heat inside fluid tanks that need internal heating.
