220V 1000W 1/8" 3/8" Electric Screw Immersion Cartridge Heater with Thermostat

Product Description

220V 1000W 1/8" 3/8" Electric Screw Immersion Cartridge Heater with Thermostat

Our cartridge heaters are most frequently used for heating metal parts by insertion into drilled holes. Two basic forms, high watt density and low watt density.
High density cartridge heaters are available with various termination styles and mounting attachments. In high-density cartridge heaters the resistance wire loops are positioned as close as possible to the outside shell. With advanced technology and sturdy material design, it ensures superior heating efficiency, high stability and long service life.

Features

1.Easy installation: The single-end wire-out design saves installation space and is especially suitable for scenarios where the heating hole is deep and only one side can be operated (such as deep hole heating in molds).

2.Concentrated heating: Heat is conducted from one end to the other, which can form a high-temperature zone locally and is suitable for applications requiring directional heating.

3.Compact structure: Customizable length (typically 50-1000mm) and diameter range (3-30mm) to meet different heating hole requirements.

4.High efficiency and durability: The magnesium oxide insulation layer has a high thermal conductivity (≥2.5W/m·K), with a thermal efficiency of over 90%; the stainless steel casing can withstand temperatures up to 600℃ and has strong corrosion resistance.

5.Safe and reliable: Insulation resistance ≥100MΩ, withstand voltage ≥1500V, which can avoid leakage risks and is suitable for humid or high-demand environments.
