CARTRIDGE HEATERS - EXTRA-HIGH WATT DENSITY
IPERMAX extra-high density cartridge heaters are a product of Rotfil’s research laboratories. Developing an exclusive manufacturing technology, Rotfil technicians have standardised a production
first intended for aerospace industry. Such technology allows high compression ratios even on low-density insulating powders such as boron nitride (BN), obtaining a product similar to ULTRAMAX cartridges but much superior in performance.
IPERMAX cartridge heaters are the best heaters under all following aspects: -High Watt density reached
-High insulation at high temperatures
-Same insulation values when cold
-Max. working temperature over 1000 °C
-High thermal conductivity
-Maintenance of the electrical and mechanical characteristics throughout time
-Ability to work in open air
-Ability to work in spoiled seats or in seats with too big clearance
-Ability to work in heat-accumulating or low-dissipation environments
-Very long life duration
It is recommended to use these heaters not only when the work conditions required are incompatible with other types of heaters but also when there is the need to use an extremely reliable heater.
Particularly suitable for applications in the aerospace, medical, military industry, or in high-output fully-automated plants with high downtime costs. Due to its very special construction technology, IPERMAX cartridges are currently manufactured only in diameters: 12.5 -14 -16 mm. Ask our Customer Service for other sizes.

CARTRIDGE HEATERS - HI-TEMP. SUPER SEALING - ULTRAMAX SC 400
ULTRAMAX SC 400, a cartridge with total waterproof sealing, compatible with high temperatures.
The magnesium oxide in the core of all high-power density cartridge heaters is an excellent
electrical insulator and a good heat conductor. However, it has a high hygroscopic characteristic, therefore heaters that are not “turned on” and are in a humid environment tend to lower their level of insulation, which sometimes can cause safety devices to intervene at start-up. In the worst cases the heaters might get irreversibly damaged by short circuit.
If the temperature of the heater’s head does not exceed 260°C, the head sealing can be made in resins or silicone, but for higher temperatures or higher safety ratios, other solutions are required.
Rotfil found and patented the solution to this problem: SC 400 is a totally watertight sealant, irreversible, resistant to high pressures and continuous high temperatures of up to 400 °C.
It does not change its structure or characteristics in the years, it is resistant to water, acids, air pollution, and does not char.
SC 400 is an inorganic compound that is fused into the heater’s head in a controlled-cycle process, thus forming a cohesive seal adherent to the metal surfaces at molecular level. It totally protects all internal components from pollution and oxidation, increasing the life of the heater.
The use of ULTRAMAX SC 400 cartridges is indispensable every time you need a high safety level and high reliability. Typical application fields include medical and surgical equipment, aerospace, nuclear-energy, military.

FOIL HEATING ELEMENTS
Flexible heating foil is the result of printed circuit technology (etched foil) and was developed in order to solve specific problems in advanced market sectors such as the space and aviation
fields. In a relatively short time, the heating foil has found applications in many other fields, allowing users to solve problems of particular importance thanks to the following characteristics:
Can be set to vary heat concentrations to optimize distribution
Minimum heat dispersion in case of external application on the object to be heated
Can be moulded
Economical in many applications
Minimum weight and thickness:
Mica 0,9 mm
Kapton 0,15 mm
Silicone 0,8 mm
Polyester 0.15 - 0.25
Teflon 0,8 mm
Flexibility
Working temperature
Mica max working temperature 500° C
Polyimide max working temperature 260° C, with adhesive 175°C

HIM HEAT-COOL-COMBINATIONS
Intensive Heat-Cool-Combinations are mainly used in extrusion (e.g. tube extrusion, hose extrusion, fabrication of profiles and foils). The injection moulding of fibreglass filled polymers is also
an interesting application.
HIM Intensive Heat-Cool-System with mineral insulated Band Heater(s) and aluminium profiled cooling system works in diameters from 100 mm with operating temperatures up to a maximum of 450°C. An economic cooling system due to the usage of standard parts. Five basic are to combine various after application in numbers and arrangement.
Pre assembled halves provide easy handling. Both halves cover most of the extrusion barrel. This provides a homogeneous heat distribution and therefore improves temperature control which results in improved quality of the extrued products.
The special geometry of the elements with the cooling ribs and structured surface enlarges the radiation surface. This is suitable for applications with plastics requiring high shear (frictional heat) and at the back zones where high pressure and simulataneous temperature increase occurs.
The HIM is recommended for fast product changes and simulataneous temperature change. Melt throughput is increased. A homogenous temperature control is provided which is an advantage when used with temperature sensitive plastics. Further advantages are energy savings due to low operating times of the blowers, no corrosion of the surface at higher temperatures (450°C max) and flexible in length due to block building system.
