CERAMIC BAND HEATERS

Anupam's Ceramic Band Heaters were developed to meet industrial requirements for high temperature long lasting heaters. They are ideally suited to comply with today's new resins, which calls for ever-increasing process temperatures.

An additional advantage of the Ceramic Band Heaters is that they transfer heat through conduction and radiation. This makes their tightness on barrels less critical; thus they are less prone to thermal expansion problems.

Theoretically, there are no restrictions on the diameter that ceramic band heaters can attain; however, because these heaters utilize ceramic tiles that are available only in specific lengths, the width of these heaters falls within a certain incremental range of sizes.

Construction
Ceramic band heaters are designed with spirally wound inner resistance coils evenly threaded through interlocking insulated ceramic “tiles”. The ceramic core, or “mat” of tiles is housed beneath a stainless steel sheet with serrated edges. This combined assembly of the Ceramic Band Heater offers a flexible heating system that yields efficient transmission of conduction and radiated heat. The heat of the Ceramic Band originates from the inner coils that conduct heat at maximum temperatures. The heated coils evenly deliver heat through the ceramic tiles which radiate energy to the barrel. We offer a variety of Ceramic Band styles with customized configurations.

MICRO TUBULAR COIL HEATERS

Anupam Heaters’s Micro Tubular Coil Heater is a small, linear heating element that can be formed into different shapes and configurations. Also known as a Hot Runner Heater for its extensive use in Hot Runner Systems, the Micro Tubular Coil Heater is a high performance heater which allows high wattage in a limited space.

The ability to shape a Hot Runner Heater when cold enables to heat up parts with different shapes. During coiling, the gap between turns of coil can be modified to compensate for the heat losses at each end of the coil or to insert the heating element into slots.

Micro Tubular Coil Heater has a larger cross-sectional area and is thus capable of greater power than Micro Coil Heaters. For this reason the Hot Runner Heater is used in hot runners with adequate space and where high heat densities are required. Micro Tubular Coil Heater can accommodate type “J” or “K” thermocouple sensors.

Since the measurement point of a built-in thermocouple is situated in the Hot Runner Heater and never where the heat is actually required, our Micro Tubular Coil Heater with a thermocouple makes particular sense where the application allows the use of larger processing temperature or where the installation location or the design requires protection against overheating. The standard connection for our Micro Tubular Coil Heater is a 1000 mm PTFE-insulated lead wire with Fiberglass sleeve with protective earth conductor lead.

CONSTRUCTION:
Anupam Heaters’s Micro Tubular Coil Heater feature precision wound parallel coil elements fusion welded to nickel cold pins.  The element assemblies are embedded within high purity Magnesium Oxide Insulation and encased in Stainless Steel metal sheath. This Hot Runner Heater is swaged to the final rectangular, square or round cross-sectional dimensions to compact the internal core and High Purity insulation to near theoretical density. This high density construction maximizes heat transfer and dielectric properties and provides the high level of reliability and performance required for even the most demanding of applications.

The Hot Runner Heater is annealed after manufacturing, thus acquiring a high malleability that allows their being subsequently bent into any complex shape, with extremely narrow bending radius.

INSTALLATION & MAINTENANCE RECOMMENDATION:
Ceramic Band Heaters are very flexible and can be made in large widths and one-piece construction for easy installation eliminating heat losses between narrow bands and sharply reducing labor cost in installation.
Before installation & during operation, the surface of the barrel and ceramic band heater must be clean and free from all contaminants that might liquefy under heat and find there way into the heater elements, carbonizing and becoming conductive. The smallest amount of contamination can cause electrical shorts creating heater failure.
Tighten the Allen bolt until the serrated edges become firmly in direct contact with the barrel to get the uniform contact. Do not over tighten, as to the point where serrated edges begin to collapse and thrust outwards. Unlike all other types of band heaters, Ceramic heater works on conduction and radiation principle and they do not require the same clamping force essential on all other types of band heaters.
To prevent the overheating and heater failure, adequate temperature controllers should be installed. Thermocouples must be kept free of contaminants and checked for good response to temperature changes. A bad thermocouple can be the cause of destroying an entire heating Zone.
Keep all electrical connections properly protected to avoid accident.
Never perform any type of service on heaters without disconnecting all electrical power.
Incorrect wiring is a common cause in heater burn out.
Qualified person should do the electrical wiring of heaters

SEALED MICA NOZZLE HEATERS

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.

CONSTRUCTION:
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 transfer—a performance solution lowering element wire temperatures and increasing heater life.

MOUNTING:
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.

STORAGE & COMMISSIONING:
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.

TUBULAR HEATERS

Anupam's versatile Tubular Heaters are custom-formed in a wide variety of shapes to correspond to your requirements.

Tubular heaters can be used in almost any application. Straight Tubular Heaters can be clamped to metal surfaces or inserted in machined grooves for conductive heat transfer. Or use a formed Tubular to provide consistent heat in any type of special application. Tubular Heaters may be clamped, immersed in liquids, cast into metal or spaced away from the work as radiant heaters. They may also be positioned in ducts or vessels for heating air or other gases. 

Tubular Heaters of proper rating, material and shape can be used in most heating applications requiring process temperatures up to 750o C (1382o F).

CONSTRUCTION:
Anupam’s tubular heaters use 80% Nickel 20% Chromium high grade coiled resistance wire as a heating core. This core is welded at both ends to pins that provide a cold section that varies in length depending on the application requirements. The coil-pin assembly is precisely centred inside a heavy gauge, oversize metal tube, and embedded inside a 96% pure, high-grade MgO insulating medium. This assembly is then compacted through a roll-reducing process that reduces the outside tube diameter to its final size, and transforms the MgO matrix into a rock-hard solid that acts as an excellent heat transferring medium, as well as an electric insulation with high dielectric strength. Finally, heaters are annealed inside a high-temperature furnace to eliminate internal stresses accumulated during the cold-forming and roll-reducing process to make them soft. Heating elements are then formed into special shapes, or supplied in their straight form. Proper electrical terminations are added to the final product.

ADVANTAGES:
Constructed with epoxy or silicone seals to resist moisture contamination (Oxidation and corrosion resistance).
Compacted with insulating MgO that allows heat to transfer away from resistance wire to the sheath material and media with faster efficient heat up.

FINNED TUBULAR HEATERS

Anupam’s Finned tubular heater are the most common type of heating elements used for heating air and other gases. The fins along the tubular length assist in even heat dissipation. All elements have mild steel fins copper brazed to the tubular heating element sheath unless otherwise specified.

Duct heaters use fin tubular elements within its design to help reduce the watt density. It also allows for more consistent air flow streams within the duct and increases the life longevity of the elements.

In applications where tubular heaters are exposed to forced convection, placing fins around tubular heaters increases their surface area and thus improves their heat transferring capacity. Finned tubular heaters, compared to regular tubular heaters, run at lower surface temperatures for the same watt densities when placed in identical air streams

Despite their advantages, finned tubular heaters are not recommended for applications where outlet air temperatures exceed 600°F.

The physical characteristics of a finned tubular heater play a major role in the effectiveness of its heat transfer.

Fin material is continuously spiral wound tightly onto the element surface to increase the convective surface area for air and non-corrosive gas heating. Fin spacing and size have been tested and selected to optimize performance. Steel finned units are then furnace brazed, bonding the fins to the sheath to increase conductive efficiency. This allows higher wattage levels to be achieved in the same flow area and produces lower sheath temperatures prolonging heater life. For higher temperature or more corrosive applications, stainless steel fins securely wound on alloy sheath are available.

Application conditions such as vibration and toxic/flammable media should be taken into consideration when installing heaters.

The sheath material of a finned tubular heater and its watt density are two critical factors that affect its durability.

FEATURES:
Custom-formed to meet specific requirements
Precision wound resistance wire for long heater life
Superior heat transfer
Variety of lengths available
Easy to install

THERMOCOUPLES

Anupam produces top of the line temperature sensing devices also known as Thermocouples. A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end. When the junction of the two metals is heated or cooled a voltage is produced that can interpreted by a temperature controller, high limit or display device. There are two common constructions for these: Tube and Wire and Mineral Insulated. The tube and wire uses an empty stainless tube with a wire inside which has a welded tip incorporating the wire junction. This construction is typically used to 480ºC. The Mineral Insulated construction uses a highly compacted stainless sheath with solid conductors encased in magnesium oxide insulation. This construction offers a wider variety of diameters, allows for the sensors to be bent in the field and for temperatures to 1200ºC. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options.

In Mineral Insulated (MI) thermocouples, elements are surrounded by compact inorganic insulation (MgO) and housed in stainless steel or heat resistant alloy sheath to protect it from environment. MI thermocouples have a lot of advantages as compared to conventional beaded thermocouples. These thermocouples are available in long lengths which can easily be wound into coils making them easy to transport. They can be flattened or bends without affecting the sheath or the cores. This flexibility enables them to be easily installed. They have a small sheath diameter allowing the thermocouple to be placed in smaller areas. Ceramic is a brittle material and when placed as beads may succumb under conditions with vibrations. MI thermocouples have high vibration strength which make them apt for such applications. These thermocouples are tested to ensure high quality. All assemblies are tested for Insulation resistance, Visual & Dimensional checks, and Single point calibration. Other tests offered "Conductor loop resistance", "Specific temperature calibration", "Nitrogen leak test", "Hot IR test".
