NormaWatt: cartridge heaters

Economical heating

Cartridges with low voltage charge are the most suitable for moderate heating up to 300ºC. Made with best quality stainless steel tube that can be found, or with other material such as copper, brass or aluminium. Everything is perfectly calibrated, such as the exterior. A long-life ceramic piece is inserted into the tube and resists every continuous temperature variation, together with the best possible thermal conductivity, as the piece is in contact with the wall of the tube, gives a perfect heat distribution. A first quality heater wire is inside the ceramic piece. The nickel-chromium heater wire is the most suitable in the manufacturing of cartridge heaters due to its high degree of tolerance to high temperatures. Coated with checked granulometric magnesium oxide, covering the whole inside of the cartridge heater. Therefore, a perfect conductivity between the heater wire and the heater is obtained.

Technical data

Welded watertight base (Tig) resists pressure up to 60kg/cm2 Calibrated stainless steel AISI 304/ 316 / 321 Ceramic disc insulator. Checked pure granulometric magnesium oxide. Nickel-chromium 80/20 heater wire. Melting point 1400ºC. Ceramic core. Hard ceramic head. Conductor lead. Hard refractory paste.

The unique Maxiwatt manufacturing system, together with its electronic system, makes it possible to separate the spirals, guaranteeing the same temperature around the whole perimeter and length of the cartridge. Therefore, an uniform and long lasting temperature is obtained.

Use

Regular cartridges are particularly suitable to every place where you need some kind of temperature
