Component Specifications

Definition
A cylindrical heating cartridge designed for insertion into vaporizer or generator systems to provide controlled electrical resistance heating. This component converts electrical energy into thermal energy through Joule heating, maintaining precise temperature ranges required for vaporization processes in industrial applications. It features integrated temperature sensors, robust insulation, and standardized mounting interfaces for reliable operation in continuous industrial environments.
Working Principle
Operates on Joule heating principle where electrical current passes through a resistive element (typically nickel-chromium alloy), generating heat proportional to current squared times resistance (P=I²R). The cartridge design ensures uniform heat distribution along its length, with temperature feedback via integrated thermocouples or RTDs enabling closed-loop control systems to maintain target temperatures within ±1°C accuracy.
Materials
Resistance wire: NiCr (80/20 nickel-chromium), Sheath: Incoloy 800/840 (iron-nickel-chromium alloy), Insulation: High-purity magnesium oxide powder (MgO ≥96%), Terminal pins: Nickel-plated copper, Seals: Ceramic fiber gaskets
Technical Parameters
  • Length 50mm-300mm
  • Voltage 120V/240V AC
  • Diameter 8mm/10mm/12mm/16mm
  • Power Rating 500W-3000W

Frequently Asked Questions

What maintenance is required for heating cartridges in continuous operation?

Regular inspection for sheath oxidation every 6 months, terminal connection tightening quarterly, and insulation resistance testing annually using megohmmeter at 500VDC.

How are heating cartridges protected from dry firing?

Integrated thermal fuses (typically 750°C) and control systems with temperature feedback prevent operation without proper immersion in heat transfer medium.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
