Elmec Heaters and Controllers

Elmec is a well-known company engaged in designing, manufacturing and exporting the highest quality of cartridge heater, which are available in low, medium and high watt densities with internally externally connected leads. Our company designs, manufactures and exports split type cartridge heaters for high temperature applications. Applicationof high technology enables usage with high watts in small spaces. Advanced manufacturing process ensures vibration proof heaters 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 fitting of the cheater in the hole facilitates good heat exchange between the surfaces of heater and mass to be heated thus increases the heater life and reduces cenergy loss.

Mounting bore clearance:

The gap between the heater O.D and the bore I.D should be very close.

To determine Fit:

• Fit = Largest hole I.D - Min heater O.D


• Ex: Heater O.D = 12.5 mm (± 0.06mm std. tolerance)


• Hole I.D = 12.6 mm (± 0.02mm hole tolerance)


• Min heater O.D = 12.44 mm


• Largest hole I.D = 12.62 mm


• Fit = 12.62 - 12.44 = 0.18 mm (max permissible clearance)

Refer Operating temperature Vs Watt density graph to find max permissible clearance.

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
We design and manufacture Split Type Cartridge Heaters, which are developed for high temperature application. Helically wound resistance coli are placed inside the tube filled with MgO powder and compacted for faster and efficient heat transfer.

Features

• Excellent heat transfer.


• More clearance can be provided for inserting split type cartridge. Heaters compared to standard conventional

cartridge heaters.

• 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

Our company, Elmec Heaters & Controllers can design, manufacture and export any intermediate diameter and length, send drawing or sample for special size.
