Easy installation
They are especially designed for quick adaptation in moulds or surfaces where the use of rivets either causes problems or impossible to use. Cuadrawatt cartridges are the better choice. Cartridges with a low charge of watts are most suitable for moderate heating up to a maximum temperatures of 300ºC. The square tube is made of prime quality stainless steel.
All the tubes are perfectly calibrated both inside and outside, into which a long-life ceramic piece is inserted. The tube stands up to a continuous temperature variation and has the best possible thermic conductivity, as the ceramic piece is in contact with the wall of the tube, which makes a perfect distribution of heat possible. The heater wire is inside the ceramic piece. The nickel-chronium heater wire is of first-class quality and is the most suitable for the manufacture of cartridge heaters due to its high tolerance to high temperatures.
Everything is coated with checked granolumetric magnesium oxide. The whole interior of the cartridge is also coated. Therefore, there is excellent conductivity between the heater wire and the object to be heated.

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