Cartridge Heaters

We are one of the leading organizations engaged in manufacturing and supplying a wide range of Industrial Heaters. These products are widely appreciated in the market for durability, high performance and easy installation features.

Now a days demand for cartridge heater in the industry is raising year by year. For best cartridge heaters contact Electron Systems, the number one manufacturers and suppliers of different types of a cartridge heaters in both low density and high density. The responding time of high density cartridge heater is very fast and they are used in various industries like printing, packing and automobile, plastic, food processing, footwear and shoe industries etc. Electron Systems manufactures and supplies the Split type cartridge heater, which is specially developed for higher temperature application. Using MgO powder insulation we assure to get fast heat transfer and high electric strength. It provides more wattage in the small sizes. We suply our heaters all over India including Bangalore, Mumbai, Pune, Chennai, Hyderabad, Ahmedabad, New Delhi, Kolkata and other cities.

Cartridge Heaters (Low Density)

Low Density Cartridge Heaters are fabricated using high quality nickel chrome wire. They are wound helically and placed inside ceramic insulators. Cartridge heaters are tubular in shape and very compact. They are used for process heating in various industrial applications. Our low density cartridge heaters are known for efficient heat transfer, long life, corrosion resistance and for high temperature range operations.

Cartridge Heaters (High Density)

Electron's High Density Cartridge Heaters are manufactured with most advanced technology and quality raw materials, enables usage with high watts in small spaces and advanced manufacturing process ensures our heaters are vibration proof and thus ensures excellent reliability in heavy duty working conditions (Like Plastic Processing, Printing, Packaging and automobile industries where the heaters are subjected to heavy vibrations). The high performance is achieved by correct installation of the cartridge heaters. The perfect fitness of the heater in the hole facilitates good heat exchange between the surfaces of heater and mass to be heated thus increases the heater life and reduces energy loss.

Features :

» Very compact construction to minimize shocks and vibrations.
» Very good heat transfer rate.
» Sheathing Materials: SS 304 and 316
» Sheath temperature up to 800 degree C.
» Inbuilt thermocouple J or K type

Applications :

» Dies, Patterns and Moulds.
» Liquid and Gases heating.
» Hot Stamping processes.
» Plastic processing equipments.
» Footwear and shoe making machines.
» Labelling and Laminations.
» Food processing machineries.

To determine Fit :

Fit = Largest hole ID - Min heater OD
Eg : Heater OD = 12.5 mm (± 0.06mm Std. tolerance)
Hole ID = 12.6 mm (± 0.02mm hole tolerance)
Minimum heater O.D = 12.44 mm
Largest Hole I.D = 12.62 mm
Fit = 12.62 - 12.44 = 0.18 mm (Maximum permissible clearance)

Refer Operating temperature Vs Watt density graph to find maximum permissible clearance.
Diameter mm 6.5 8 10 12.5 16 19 25
inch 1/4 5/16 3/8 1/2 5/8 3/4 1
Length Minimum (MM) 35 35 40 40 50 60 75
Maximum (MM) 250 250 500 500 1500 1500 1500

Terminals :

Fibre glass or Teflon wire crimped or welded to terminals. Fibre glass wire with SS metal braiding. Wires protected with SS or GI flexible conduits. All wires are available in straight or right angle exit. Drawing or sample required for special type terminals.

Split Type Cartridge Heaters

Electron Systems Split Type Cartridge Heaters are developed for high temperature application. Helically wound resistance coil is placed inside the tube filled with MgO powder and compacted for faster and efficient heat transfer.

  • » Split-heaters expands to maximize heat transfer and contracts when cold for easy removal from bore.
  • » Ideal for use in oversized bores. Eliminates need for tight fits, tight tolerance bores.
  • » 1A single continuous heating coil ensures a uniform temperature profile. No sections to burn out as in conventional cartridge heaters.

Features :

» Excellent heat transfer.
» More clearance can be provided for inserting split type cartridge.
» Can be inserted and removed easily. Longer life.
» Uniform heat transfer.
» Available in SS304 SS316 sheaths.
» Hot zone up to the tip of the element.

Applications :

» Plastic Processing & Packaging Machinery.
» Injection & Blow Moulding.
» Extruders.
» Foundaries.
» For fastening of Turbine Bolts.
» Soldering pots.

When ordering please specify :

» Dia & length of the heater.
» Wattage and voltage.
» Type of terminal.
» Drawing for special type configuration.

Available Dia: Mm 6.5 8 10 12.5 14 16 19
Length(mm) Min 40 40 40 50 75 75 100
Max 500 600 900 1500 1500 1500 1500
