liquid heater / cartridge / conduction
These heaters are characterised by a high specific power and a high reliability: These qualities are essential in the applications for which they have been conceived. These heaters can reach specific powers as high as 50 W/cm² and operating temperatures up to 750°C. PIROWATT cartridge heaters power supply cables are embedded into the heater head without junctions or stiff parts: this manufacturing solution has eliminated all the problems and allows to limit the non-heating (neutral) section to a 3 ÷ 4 mm. These heaters are used in the heating of moulds, plates, injection nozzles and hot-channel injection nozzles. They can be employed, inserted into appropriate slots, in the heating of all metallic masses.
