MICA Band Heaters




MICA INSULATED NOZZLE, BAND, STRIP, PLATE SQUARE & RING HEATERS
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 a nd terminal boxes offer great flexibility for field wiring.

Ceramic Band Heater




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. Ceramic Band Heaters design consist of a helically wound resistance coil made from 80/20 nichrome wire, evenly stretched and precisely strung through a specialty designed ceramic insulating bricks forming a flexible heating mat. The ceramic heating mat along with ceramic fiber insulation is placed on a stainless steel housing made with serrated edges providing maximum flexibility foreasy installation.

APPLICATION

• Injection Moulding
• Blow Moulding
• Extrusions
• Pipe and drum heating

• Ideal for use on Injection and extrusion barrels (when processing low, medium and high temperature resins)

MICA / Ceramic Strip Heater




Mica Strip Heaters are constructed by winding a nickel-chrome resistance ribbon around mica insulation and encapsulated in a stainless steel sheath. They are available in an extensive variety of sizes and shapes with options for holes, notches,arid cut-outs. A number of threaded terminals, wire lead options and terminal boxes-offer great flexibility for field wiring. These heaters are ideal for plastic processing applications and for anywhere heat is needed on a flat or curved surface.

CERAMIC STRIP HEATER (WITH & WITHOUT FINS)
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.
Fins increase the heat transfer surface area to allow higher wattages than standard Strip Heaters. These are intended to be operated with a substantial airflow and are typically used in heating tunnels, dryers or any application that requires a hot air source.

MICA Energy Saving Heaters




Unique Insulation Plus Band Heaters are Specifically designed and engineered to meet the ever increasing demand for energy conservation and to improve operation efficiency capable of generating higher temperature essential to process today's high temperature resins.
Energy Conservation is achieved by using 1" thick Ceramic fiber insulating blanket on the outer surface increasing the overall outer diameter by 2"(Minimum Length Required is 4"). Reducing power consumption upto 30% because of low thermal conductivity of the ceramic fiber insulation, the external surface temperature of the insulation plus ceramic band heater is approximately 80°C while running the inside surface temperature at 300°C.

APPLICATION

• Injection Moulding
• Blow Moulding
• Extrusions
• Pipe and drum heating

• Ideal for use on Injection and extrusion barrels (when processing low, medium and high temperature resins)

FEATHERS
