Elmec Low Density Catridge Heaters are made of helically wound nickel chrome resistance wire evenly stretched and placed in ceramic insulators. The elment assembly is inserted into Brass/SS 304 tube. High grade MgO powder is filled in the remaining space inside the ceramic insulators to increase thermal conductivity, dielectric strength and heater life.
- Low watt density heaters are available in brass or SS 304 sheath.
- Medium & High watt density heaters are available in SS 304 sheath.
- Braided Wire, straight or right angle exit.
- Uniform surface temperatures.
- Flange type optional Braided wire.
- Max temp for SS tube 400oC, for Brass tube 200oC.

The inner diameter of the hole can be between 0.15mm and 0.30mm larger than the cartridge diameter. The lesser the clearance between the heater and the bore diameter, the longer will be its life.
- Diameter - Min 8mm to Max 45mm.
- Length - Available in any desired length.
- Max watt density 3.5 watt/sq cm.
- For higher wattage and high temperature we recommend high watt density cartridge heaters.
