Watlow Mineral Insulated Nozzle Heaters

Product Overview

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.

Overview

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.

Features & Benefits

  • 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.
