Sealed Nozzle Heaters

Sealed Nozzle Heaters

Their high watt-density per square centimeter allows a fast and safe reaching of the required working temperature

During manufacturing, the heaters are submitted to extremely high pressure that ensures high insulation, excellent thermal exchange, lack of internal voids, perfectly smooth contact area for an optimum and uniform heat transfer to every part of the nozzle.

The inner profile is perfectly round, providing a perfect coupling with the nozzle. The size of the connecting cap is minimal, giving extremely limited overall dimensions.

Power connection is performed by a metal braided cable, standard length 1 m, with two nickel power leads plus a galvanized-copper ground lead.
