Advanced production technology and high quality materials allow to make special-purpose heaters. Their power and dimensions cannot be achieved in the standard production process.

Technological processes
Strzałka w dół

  • Cutting the pipe
  • Winding the resistance wire
  • Backfilling the heating element
  • Welding the bottom covering the pipe
  • Rolling
  • Forming the heater
  • Sealing
  • Current connections
  • Design
  • Making a winding core


General structure
Strzałka w dół

Hot nozzles are made of stainless steel AISI 304 and AISI 321 and beryllium bronze. Thanks to the applied production technology, they achieve high power in relation to the heating surface. The use of the highest quality materials ensures high precision and durability of the product. Subjecting the nozzles to appropriate technological processes guarantees a high operating temperature, and the additional use of a sensor allows to achieve a precisely defined temperature and protects the product against damage.


Characteristics of the elements:

Nickel-chromium resistance wire, properly compacted with high quality magnesium oxide;
Current outlet in the form of a copper conductor in a PFA coating or a nickel conductor in a fiberglass braid;
Possibility of installing a temperature sensor (type K thermocouple, type J thermocouple);
Cold zones (non-heated) depending on the diameter of the heater (min. 30 mm from the wiring side).
