sectional ceramic heaters

Traditional solution for indirect heating

DESCRIPTION

These heaters represent most usual solution for indirect heating of fluids and gases. Assembled into protective tube they are not in direct contact with fluid. Main advantage is possibility of simple and quick replacement of ceramic cartridge with resistance coil without dismantling protective tube. In addition, they are suitable for heating oil, bitumen and other mediums which can change the structure, carbonize and burn due to high temperatures on the heater surface which is common for system of direct heating.
Ceramic sectional heaters have resistance coil embedded in grooves on ceramic stars - segments. Resistive wire (Ni-Cr) is used for coils whilst segments material is refractory technical ceramic.

APPLICATIONS

  • Thermal oils, duplicators (reactors)
  • Oils for lubrication, hydraulic oils, turbine oils, gearbox oils
  • Drinking and technical water, both in open and closed systems
  • Steam generators
  • Fluids for cleaning, various solutions and emulsions
  • Fuel oil, heavy oil, bitumen
  • Fluids in galvanic baths, basins with diluted acids, alkaline baths
  • Special fluids and gases, gases in steam form
  • Dryers, industrial furnaces
