Anupam's Ceramic Strip heater provides the ability to withstand higher temperatures . Anupam's Strip heaters, often considered component heaters, are a simple way of using surface area to transfer heat effectively. A fairly inexpensive way of heating surfaces or small areas, strip heaters are an excellent solution to meet any budget. If strip heaters are used as a radiant heater, they have can have fins to maximize surface area and heat transfer to the air.

Our Ceramic Strip Heaters are dependable and reliable flat heating elements designed to provide efficient heat to flat surfaces from common to industrial applications.The seamless sheath design of Ceramic Strip Heaters makes them dimensionally stable in milled slots.

Ceramic Strip Heaters are constructed with ceramic insulation that quickly conducts heat from the resistance wire to the sheath resulting in low internal temperatures and long heater life in the most demanding applications. Precise placement of the resistance wire provides uniform sheath temperature across the width and along the entire heated length. This is an extremely rugged construction capable of high temperatures and high watt densities.

The inner construction consists of wound nichrome resistance coil. The inner flexible wire is strung through ceramic insulator pieces. The coils are attached to the screw terminals, or high temperature lead wires, for a positive connection. MgO (magnesium oxide) is used to fill and pack open areas surrounding the coils. The MgO material helps increase the elements thermal conductivity and dielectric strength.

• High heat transfer rates and fast heat up


• Ceramic construction for higher temperatures

  MOUNTING SUGGESTIONS
  

  Ceramic Strip heaters must be clamped securely along a smooth metal surface (along their complete length). When a Ceramic Strip Heater is supported by mounting tabs, ensure that the terminal is secured firmly, and that the opposite end remains loose to allow for expansion. Do not over-tighten nuts when installing, as over-torquing terminals will create internal heater damage.

Nozzle heaters, Anupam's nozzle band heaters "COIL TYPE" are capable of performance under the most adverse conditions. Highly recommended for processing high temperature resins to eliminate premature failures due to burn out process material leakage. Heat transfer is based on conduction as well as on radiation principle, which not only improves the thermal efficiency but easy to assemble on nozzles as no pressure on heating surface is essential. Even unskilled operator can fit the heater with no risk of failure of the heater. Coil Type Nozzle Heaters are specially designed to prevent the failures of heaters against the leakage and contamination of plastic material at nozzle position. This heater can meet the higher temperature requirement prior to moulding at nozzle position.

Sealed Mica Nozzle Heaters are hermetically sealed for liquid plastic during the manufacturing process. The connection between the heating element and the leads is protected by a special fitting made of 1 mm thick brass or stainless steel, without welding which allows a high mechanical strength in the most delicate area of the heater.

During manufacturing, the Sealed Mica Nozzle Heaters are submitted to extremely high pressure that ensures high insulation, excellent thermal exchange, lack of internal voids, perfectly smooth contact area for an optimum and uniform heat transfer to every part of the nozzle.

The Sealed Mica Nozzle Heaters are available in either Brass or Stainless Steel versions, depending on the application. It is recommended to use stainless steel nozzles where the molding or extrusion of PVC is involved as stainless steel will withstand the corrosive fumes far better.

The Sealed Mica Nozzle Heaters are a rugged product that resists very well to wearing and shocks. The inner profile is perfectly round, providing a perfect coupling with the nozzle. Size of the connecting cap is minimal, giving extremely limited overall dimensions. Power connection is performed by a Standard metal braided cable with Length of 1000 mm.

A thin layer of the "high" thermal conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, "low" thermal conductivity layer backs up the element wire, directing the heat inward toward the heated part. The result is more efficient heat transfera performance solution lowering element wire temperatures and increasing heater life.

Good thermal contact between the element and metal surface to be heated is essential. It is therefore important that elements are clamped on tightly and that clamps are tightened again when the element has reached operating temperature. Correct fitment and tightening up of these heaters is critical to ensure not only excellent heat transfer but also longevity.

Elements are susceptible to moisture and should be stored or used in a dry environment. It is recommended to heat up the elements gently after a prolonged period out of commission. This allows moisture to escape and prevents damage to the elements. Some temperature controllers have a soft-start feature, but a similar result is achieved by turning the temperature controller down initially.

• Contributes to faster heat-up and throughput for increased productivity


• Gives an almost instant response to temperature control


• Resists contamination by overflow of plastic or other free-flowing materials


• Eliminates cumbersome clamping straps, making installation easier

Mica band heater, Mica Band Heaters are constructed by winding a nickel-chrome resistance ribbon around mica insulation and encapsulated in a stainless steel sheath. It is then formed to the desired diameter for installation over a dies, barrels and nozzles. They are available in an extensive variety of sizes and shapes with options for holes, notches and cut-outs. A number of threaded terminals, wire lead options and terminal boxes offer great flexibility for field wiring.

One Piece Construction:To be used when a heater can be slipped over a barrel without having to expand the heater extensively.

Two Pieces / Multiple Segment Construction:Two piece or multiple segment bands make installation far more convenient and are recommended for applications over a 14" diameter. Spring loaded clamping is recommended.

• Ensure Heater ID same as OD of cylinder/nozzle


• Eliminate contamination of oil, plastic, dirt etc on cylinder surface to avoid carbonizing & shortening heater life


• Secure firmly to avoid Air gap and also to compensate for normal expansion, re-tighten periodically


• Maintain temperature controls & accessories in good working condition to avoid over heating condition


• Protects leads from abrasion


• Avoid process material leakage to terminal
