Since 1969, date of its foundation, Crei has started with the production of cartridge heaters.

At the very beginning the LD series, low power density cartridge heaters, have been designed and developed according to the traditional technology where the wire spiral is housed inside a ceramic insulator which is in turn surrounded by a mass of uncompacted magnesium oxide.

Several years of experience mainly within the packaging industry made the time ripe for starting the production of the first cartridge heater dipped in a compacted magnesium oxide mass. The MD series, medium power density cartridge heaters, was born ensuring greater reliability to mechanical stress.
