Ceramic Band heaters
The quality of the raw materials used, as well as the experience and the extreme care with which we are assembled, make this type of electric heaters of proven efficiency and reliability. The ceramic fiber insulating thick 1 / 4 “, joined the resistive wire in high-quality steel alloys can withstand high temperatures provides an efficient heat transfer and energy savings of 25% compared to similar heaters without thermal insulation.pared to similar heaters without thermal insulation.
This graph shows the energy saving of around 20% obtained when using a ceramic band heaters than with mica insulation. This result is the result of a laboratory test after 24 hours of continuous work.
- High heat and limited time to reach the required temperature range, due to the fact that they work in direct contact with the surface to be heated.
- For specific requirements is also possible to create multi-distribution circuit, or where the total power required on-board barrel is divided between several heaters heaters connected to each other.
- Very robust
- Differentiation of temperature / power on the surface.
- Good thermal insulation
- Practical mounting / installation using hooks and springs.
- Integration of temperature sensors
- Easy cleaning and maintenance
Uses:
The rules for the application of a resistance band are a function of media type and temperature that will host that will endure.
Typical applications of this heater are:
- Extruders and melting plastic, plastic injection nozzles, nozzle casting
- Storage drums, pipes, hot water boilers
- Sterilizers, machines for the confectionery industry, wood processing machines, packaging machines and packaging machines for the textile industry
- Button dies and molds for the rubber processing
- Protect from freezing liquids
- Dissolution of solids with low melting point such as paraffin, various resins and chocolate
- Control of the viscosity of fluids paint and / or foods (syrups and honey)

- Power: All models are supplied with power cables with standard lengths of silicone (3 x 1 L = 1.5 meters), complete with plug electrical cables, or depending on specific application needs.
- Temperature Control Devices: Upon request, the ceramic band heaters are supplied complete with integrated temperature control devices are compatible for installation on drums / barrels of steel or plastic material, such as fixed thermostat bimetal thermostat limiter, fixed thermostat and integrated temperature limiter, adjustable thermostat from 0 to 180 ° C or thermocouples or PT100.
- To determine the total power needed to reach the temperature of the fluid / material to be heated, which can also result from the sum of a given number of heaters heaters installed in the airplane must be taken into due consideration the material of the container to be heated and the physical Fluid and chemical / material contained therein.
PRODUCT QUALITY ‘CERTIFIED
The entire production cycle of ceramic band heaters is subjected to rigid controls dimensional and electrical tests in accordance with regulations of our Company Quality System certified to ISO 9001:2008 and in full compliance with the requirements of current standards IEC / EN.
The various operating temperatures require different combinations of type of external and internal insulation shield, which you can choose among those, the following listed:
| Operating temperature | External sheath | Internal insulation | Electric contacts finishing |
| 100° C | Anodized iron | Micanite | Cables/ Pins/ Clamps |
| 200° C | Anodized iron | Micanite | Cables/ Pins/ Clamps |
| 300° C | Anodized iron | Micanite | Cables/ Pins/ Clamps |
| 400° C | AISI 304 | Ceramic/ Micanite | Pins/ Clamps |
| 500° C | AISI 321 | Ceramic | Pins/ Clamps |
| 600° C | AISI 321 | MGO/Ceramic | Pins/ Clamps |
| 700° C | AISI 321 | MgO | Pins/ Clamps |
The combinations referred to above are those commonly used in various applications, the temperatures specific for each type.
Improper use of the heater with respect to the initial design release the manufacturer from any liability.
USEFUL DESIGN DATA
The construction of an electrical ceramic band heater requires some knowledge of the technical data essential to the design:
- Quantity: Specify quantity requested
- Diameter (Ø): internal diameter range
- Height (H): high-end
- Power (W): (Note: the total power is equal to the sum of the 2 parts (half circles) that make up the complete body of strength)
- Supply Voltage (V)
- Wiring Type: specify type and location of electrical contacts
- Thickness of insulation (ceramic)
- Attack Type: Specify the type of attack (hook, spring, etc. …) to choose between finishing our standards (for details see data sheet “download area”)
- Other: Size and position of holes for thermocouple, resetting the thermostats temperatures (where required on-board resistance) and any other specific technical feature.
TYPE OF EXECUTION (Electrical contacts and attachment / mounting system)
The ceramic insulation of these electric band heaters band in can be realized taking into account two different parameters:
- Type of electrical contacts to be installed on the body resistance
- Attack type fastening / assembly system to predict the construction phase of the resistance
Standard Resistors Catalogue
This type of ceramic band heaters can be built to customer specifications is that in the standard version, which we have a warehouse ready for the type of power, voltage, sheath diameter and type of finish.
