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.

Technical characteristics

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.
Product range

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)
