Ceramic band heaters
Insulated cylindrical heaters for barrels, dies and process machinery requiring dependable heat input.
High-performance industrial heaters
CERAMIC
HEATERS
Insulated industrial heaters manufactured in band, flat plate, U-shaped, box and specially formed constructions.
Insulated radiant and contact heating
HEAT FOR DEMANDING
APPLICATIONS
Ceramic heaters combine a supported resistance element with thermal insulation and a protective metal outer casing.
The resistance element is carried within interlocking ceramic sections. This flexible internal assembly can be arranged around cylindrical, flat and formed components, while the insulating layer helps direct heat towards the working surface and reduce unnecessary outward heat loss.
Hotset UK manufactures ceramic heaters around the shape, dimensions, electrical rating, termination and installation requirements of the application.

Available forms
CERAMIC HEATER CONFIGURATIONS
The articulated ceramic core can be arranged within different outer casings to place insulated heat around or against the component.
Flat plate heaters
Flat ceramic assemblies for platens, tooling and machine surfaces where an insulated construction is beneficial.
U-shaped heaters
Three-sided constructions arranged around a block, manifold or component while maintaining access from one face.
Box heaters
Formed assemblies that apply heat around several faces of a die, block or specially shaped component.
Multi-section heaters
Split, hinged and multiple-piece arrangements for components that cannot accept a one-piece heater.
Drawing-led designs
Bespoke ceramic heaters developed around the geometry, openings, fixings and electrical zones of the equipment.
Heating and controlled cooling
CERAMIC HEATER /
COOLER ASSEMBLIES
Where the process requires both heating and active cooling, ceramic heater bands can be incorporated into a forced-air heater/cooler assembly.
This provides controlled heat during start-up and production while allowing excess process heat to be removed when the barrel temperature rises above the required level.
Ceramic heating bands
Ceramic heating elements provide the required process heat and can be arranged around the barrel to suit the available installation length.
Directed-air outer cowl
A fabricated outer cowl contains and directs cooling air through the assembly instead of allowing it to escape immediately into the surrounding area.
Dedicated cooling fans
One or more electrically powered fans deliver forced air through the assembly. Fan size, voltage and airflow are selected around the barrel and required cooling response.
Cooling fins
Metal fins or heat-dissipation sections increase the available surface area and help transfer unwanted process heat into the forced airflow.
Manufactured around the machine
BESPOKE HEATING AND COOLING
Assemblies can be designed around barrel dimensions, thermocouple positions, transducers, fixing points, feed openings and other obstructions. Drawings, photographs or a site survey can be used to establish the required construction.
Technical review: The operating limits of the complete assembly depend on the ceramic heater design, fan specification, cowl construction, cooling-fin arrangement and process conditions.

WHERE CERAMIC HEATERS ARE USED
Ceramic construction is suited to machinery requiring insulated, high-performance heating in cylindrical, flat or formed arrangements.
Injection moulding
Barrels, nozzles, dies and process components on plastics production machinery.
Extrusion machinery
Barrels, adapters and tooling requiring sustained and controllable heat input.
Blow moulding
Process equipment and formed components used in plastics and container manufacture.
Special-purpose machinery
OEM and maintenance applications requiring a bespoke insulated heater around a non-standard shape.
Installation matters
THE COMPLETE ASSEMBLY
DETERMINES PERFORMANCE
Correct positioning, suitable temperature control and sound mechanical installation help the heater deliver its intended output without unnecessary thermal stress.
Confirm the finished geometry
Measure the working component and identify every face, radius, clearance and obstruction around which the heater must fit.
Position the heater correctly
Install the heater in the orientation shown on its drawing and avoid damaging the ceramic core or connections.
Use suitable control
Locate the sensor correctly and configure the controller for the heater, process and required operating temperature.
Preparing an enquiry
WHAT DO WE
NEED TO KNOW?
These details allow us to evaluate the heater layout, electrical loading, terminations and finished construction.
Choosing the construction
MICA OR CERAMIC?
Ceramic construction can provide higher-temperature capability and improved outward insulation, but it is not automatically the correct option for every application. Shape, response, temperature, watt density and installation should be considered together.
