Watlow Mineral Insulated Band Heaters

Sords Electric Sells Barrel and Band Heaters from Watlow

Mineral Insulated (MI) Band/Barrel Heaters

The MI band heater from Watlow® is a high-performance heater. The band heater's performance and name are derived from Watlow's exclusive mineral insulation—a material with much higher thermal conductivity than mica and hard ceramic insulators used in conventional heaters. A thin layer of the “high” thermally conductive MI material is used to electrically insulate the element wire from the inside diameter of the heater sheath. A thicker, “low” thermally conductive layer backs up the element wire directing the heat inward toward the part being heated. 

High thermal conductivity of MI and low mass construction provides rapid response to temperature control and avoids thermal lag.

Operating temperatures up to 1400°F (760°C) allows safe melting of resins such as PEEK™, Teflon®, Ultem® and Zytel®

Higher watt densities contribute to faster heat-up and throughput for increased productivity

Stainless steel cover and side fold design resists contamination from overflow of plastic or other free-flowing materials

Attached clamp bars eliminates cumbersome clamping straps, making installation easier

Mineral Insulated Nozzle Heaters

The MI nozzle heater from Watlow is a high-performance heater. The nozzle heater's performance and name are derived from Watlow's exclusive mineral insulation—a material with a much higher thermal conductivity than mica and hard ceramic insulators used in conventional heaters.

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.

Performance Capabilities

• Heater operating temperatures up to 1400°F (760°C)

• Watt densities up to 230 W/in2 (35.6 W/cm2) are

   available on small diameter nozzle

• Maximum voltage up to 240V

Operating temperatures to 1400°F (760°C) safely melts resins such as PEEK®, Teflon®, Ultem® and Zytel®

Higher watt densities contribute to faster heat-up and throughput for increased productivity

High thermal conductivity of MI and low mass construction provides an almost instant response to temperature control

Stainless steel cover and side fold design resists contamination by overflow of plastic or other free-flowing materials

Permanently attached clamp bars eliminate cumbersome clamping straps for easier installation

Typical Applications

• Extruders

• Blown film dies

• Injection molding machines

• Other cylinder heating applications
