Patronski grijač s ugrađenim termoelementom
The construction of cartridge heater positions a nickel-chrome resistance wire precision wound around a magnesium oxide core. It is inserted into a stainless or Incoloy tube locating the resistance wire close to the sheath. The core is centrally positioned within the tube and filled with magnesium oxide powder. Nickel pins pass through the centre of the core making contact with the resistance wire at both ends. The whole is assembly is highly compacted by a swaging operation and thus ensuring excellent heat transfer to the external sheath. This allows for operating temperatures to 1600ºF and high watt densities. One end of the heater is closed with a welded metal end-disc and wire leads exit at the opposite end which is typically closed with a lava seal. A variety of wire leads and lead protection options are available. Cartridge heater can be supplied with internal thermocouples, mounting fittings and many other options.
Product Application
Grijanje vode：We recommend 10 watts per square centimetre when cartridges are to be immersed in water because the water removes the energy from the element very effectively. Commonly used as a chemical solutions heater.
Oil Heating：Commonly used as engine sump heaters. When heating some oils, only 2 vata po kvadratnom centimetru može se koristiti inače visoka temperatura površine grijača uloška uzrokuje oksidaciju ulja i nakupljanje ugljika na površini grijača. Kada se ovo dogodi, ugljik može toplinski izolirati grijač patrone, uzrokujući unutarnje zagrijavanje jedinice, često rezultira električnim kvarom.
Zračno grijanje：Elementi približno 1 vata po kvadratnom centimetru prikladni su za konvekcijsko grijanje zraka, npr. Antikondenzacijski grijači.
Die Grijanje：Razdjelnici, hot runners i torpeda.AmbalažaHot melt glue aplikatori.
