Nozzle Heaters

Product catalog summary

Overview: The document provides detailed information on Mineral Insulated (MI) Nozzle Heaters, highlighting their specifications, performance capabilities, features, benefits, and typical applications.

Specifications: MI Nozzle Heaters are constructed with stainless steel sheath materials and can operate at temperatures up to 1400°F (760°C) with watt densities up to 230 W/in² (35.6 W/cm²). They support a maximum voltage of 240V.

Performance Capabilities: These heaters are designed for high-performance applications, offering efficient heat transfer that reduces element wire temperatures and extends heater life.

Features and Benefits:

High operating temperatures allow for safe melting of resins like PEEK®, Teflon®, Ultem®, and Zytel®.
Higher watt densities enable faster heat-up and increased productivity.
High thermal conductivity and low mass construction provide quick temperature control response, eliminating thermal lag and overshoot.
Stainless steel cover and side fold design resist contamination from plastic overflow.
Permanently attached clamp bars simplify installation by eliminating cumbersome clamping straps.

Typical Applications: MI Nozzle Heaters are suitable for use in extruders, blown film dies, injection molding machines, and other cylinder heating applications.

Heater Part Numbers: The document lists various part numbers with specifications such as inner diameter, width, construction, voltage, wattage, watt density, termination type, and approximate net weight.

Nozzle HeatersMineral Insulated (MI) Nozzle Heaters Typical Applications • Extruders • Blown film dies • Injection molding machines • Other cylinder heating applications The mineral insulated (MI) nozzle heater is a high-performance heater that incorporates Watlow’s exclusive mineral insulation technology. This material offers much higher thermal conductivity than mica and hard ceramic insulators used in conventional heaters. A thin layer of the high thermal conductive Ml material electrically insulates the element wire from the inside diameter of the heater sheath. A thicker, low thermal conductivity...
