• Easy to install
• High mechanical and chemical resistance

• Jalak Electricals versatile Tubular Heaters are custom-formed in a wide variety of shapes to correspond to your requirements.
• Tubular Elements are the most versatile, dependable and rugged of any heat generation device. These qualities make it an ideal heat source for many applications. Anupam uses precision wound 80-20 nickel-chrome wire to deliver an even heat distribution to the element sheath. High purity, grade A magnesium oxide is used as the internal insulation to insure the best thermal transfer and insulation resistance. A variety of electrical terminations, mounting fittings and brackets, along with the wide array of bending options, allow for easy integration into any heating system.
  
• Tubular heaters can be used in almost any application. Straight Tubulars 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.

• JalakElectricalsThe helical wound heating wire is made of a high temperature resistant NiCr alloy. And the insulation consists of superior grade of magnesium oxide (MgO). As the heaters are swadged, even at high sheath temperature they have excellent electrical insulation and a high heat transfer. To prevent the heater from moisture the connection ends are sealed with sealing components.

• Precise forming of the heater is required to fit properly into the groove in the mould. To ensure this fit normally use a template as an inspection tool in the forming process. This template can be custom supplied or manufactured by Anupam as per customers design.

• Heaters are available in dia 6.5mm, 8mm, 8.5mm and square section of 6mm x 6mm or customize diameter.

• To manufacture Mould Tubular Heater it is necessary to have an accurate drawing showing all the center distance, Bending Radius and Degree

• Jalak Electricals 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.

FEATURES :-

• Jalak Electrical’s Mica Band Heaters are widely used to heat the dies,  nozzles,  molds and especially to heat cylinders (barrels) on all types of plastic(s) processing machinery. 
• Its main key feature is its dielectric strength.
• Mica heaters are most economic heaters.
• It’s thermal conductivity is very high. So heat transfer is very high due to “conduction”.
• Its transfer capability is the main reason behind its faster heating and cooling down function.
• Maximum watt density is 25 Watt/Square inch.
• They are available in extensive variety of sizes and sizes with shapes with options for holes,  notches and cut-outs.
• Its having best contollability because of low mass as well as lesser time required to deliver heat to the object just because of high conductivity. This will resulted for best autotune function on a control.
• We can design it in one or two piece,  which makes installation faster and easier.
• Mica heaters meets progressive requirements of the plastic processors.
• Jalak Electrical’s designing calculation on based of specific application given by as per customer’s specification gives longer life as well as proper heating requiements.
