Ceramic core heaters
The main advantages of Acim Jouanin barrel resistors lie in their ability to be extracted from a bath without draining and to resist corrosion from aggressive products (acid, etc.).
These resistors , protected by a glove finger, are commonly used for heating special baths or water heaters.

Ceramic core heaters
The main advantages of Acim Jouanin barrel resistors lie in their ability to be extracted from a bath without draining and to resist corrosion from aggressive products (acid, etc.).
These resistors , protected by a glove finger, are commonly used for heating special baths or water heaters.






Used for heating fluids when they are protected by a thermowell, the ceramics core elements can also be used to heat solids.
This technology has many advantages:
– Manufacture of very long elements (up to 6 m), where the technology of tubular elements is more limited.
– Low surface load to protect “fragile” fluids (oils, acids, etc.).
– Better resistance to fouling of heating circuits (scale, tank base sludge, etc.)
Features :
- Assembly of steatite cylinders, inserted into each other called “barrels”, held together by a threaded rod, passing through their center.
- Coiled heating wire in 80/20 nickel-chrome passing through the lateral interstices of the barrels, allowing outward radiation.
- End of the heating element protected by a ceramic head, with a diameter slightly larger than that of the barrels. The head can be offset from the heating elemnt for high temperature applications.
- Connection by threaded terminals or by wires protected by ceramic beads.
.
The ceramic core elements can be the subject of special finishes:
- The heaters can be supplied with a thermowell, to be used as an immersion heater
Generally made of stainless steel and equipped with a fixing flange or a screw plug, it can be protected by a coating depending on the nature of the product being heated. - The heating elements can be fitted with a connection box, in polycarbonate or aluminium.
The cermic core elements are exclusively custom made, according to your specifications.
Below is a summary of the main technical data:
- Barrel diameter: 36, 46, 56 mm . Other dimensions on request
- Length under head (plunging length): 100 mm minimum, maximum length 6 m , according to feasibility study.
- Heating length: 50 mm minimum then in multiples of 50 mm .
- All ceramic core elements are equipped with a non-heating zone under the head to protect the connectors. However, this zone can be extended to preserve the connections, in particular for operation at high temperature.
- Voltage: 24 V to 440V , single-phase or three-phase.
.
These heater can be mounted vertically or horizontally (to be specified during your consultation)
