Industrial Heaters & Thermocouples for Plastics Processing

Industrial heaters and thermocouples are the foundation of precise temperature control in plastics processing. These precision-engineered heating elements and temperature sensors work together to maintain optimal processing temperatures, ensure product quality, and protect equipment from thermal damage. From band heaters that wrap around extruder barrels to cartridge heaters embedded in dies and molds, proper heating and temperature measurement are fundamental to successful polymer processing.

Our Products

Product Types & Specifications

Mica Band Heaters

A mica core produces a thin, efficient heater with heat quickly transferred to the working surface for expedited heat-up. Mica provides optimum dielectric strength and heat transfer capabilities for extended heater life.

Ceramic Band Heaters

High-performance ceramic insulated band heaters for applications requiring superior heat retention, higher temperatures, and energy efficiency. Ceramic band heaters handle temperatures up to 1400°F (760°C)

Cartridge Heaters

Extraordinarily compact design producing optimum heat transfer with dielectric and physical strength for long heater life and exceptional performance. Designed for high temperature and excessive vibration applications.

Channel Strip Heaters

Versatile strip heaters for heating platens, dies, tanks, and flat surfaces. Available in various lengths, widths, and wattages with multiple termination options.

Cable Coil Heaters

Flexible heating elements for complex geometries and applications where conventional heaters cannot be used. Custom bent and formed to match specific equipment configurations.

High Performance Heaters

Advanced heater designs for demanding applications requiring maximum watt density, precise temperature uniformity, or operation in extreme environments.

Grounding:
Ensure proper grounding provisions for tinsel installations

Frequently Asked Questions

What is the difference between mica and ceramic band heaters?

Mica band heaters are thinner, less expensive, and ideal for temperatures up to 900°F. Ceramic band heaters offer better insulation, higher temperature capability (up to 1400°F), improved energy efficiency, and longer life in demanding applications. Ceramic designs typically reduce energy costs by 25-30% compared to mica in high-temperature applications.

How do I select the right thermocouple type?

Type J (iron-constantan) is suitable for temperatures up to 1400°F and is the most common choice for general plastics processing. Type K (chromel-alumel) handles higher temperatures up to 2300°F and offers better accuracy at elevated temperatures. Selection depends on your temperature range, accuracy requirements, and compatibility with existing instrumentation. Our technical team can help match the optimal thermocouple to your specific application.

What causes premature heater failure?

Common causes include contamination from plastic drool or hydraulic oil, operation above rated temperature, inadequate clamping pressure (for band heaters), incorrect wattage for the application, and power cycling stress. Proper installation, appropriate wattage selection, and maintaining clean operating conditions extend heater life significantly.

How do I determine the correct wattage for my application?

Wattage requirements depend on the mass to be heated, desired temperature rise, heat-up time, and heat losses to the environment. As a general guideline, extrusion applications typically require 20-40 watts per square inch. Our technical team can help calculate specific requirements based on your equipment and process parameters.

Can you supply heaters for older or discontinued equipment?

Yes. Rowe Equipment manufactures replacement heaters for both current and legacy equipment. We can work from samples, drawings, or specifications to create exact replacements for heaters that may no longer be available from the original manufacturer.

What is the typical lead time for heaters and thermocouples?

Standard heaters and thermocouples in common sizes are typically available for same-day or next-day shipping. Custom configurations may require 3-10 business days depending on complexity. We offer expedited manufacturing for urgent requirements.

How do I specify replacement heaters?

Provide your current heater dimensions (inside diameter, width, and wattage for band heaters; diameter, length, and wattage for cartridge heaters), voltage, and lead/termination style. We can match existing heaters or recommend improved alternatives based on your operating conditions.

What is the accuracy of your thermocouples?

Accuracy depends on the type and temperature range. We offer standard and special limits of error (SLE) thermocouples, with accuracies ranging from ±0.5°C to ±2.2°C or 0.4% to 2.0% of the measured temperature, depending on the type and temperature range. SLE thermocouples provide approximately twice the accuracy of standard calibration.

Can you provide custom-designed thermocouples?

Yes, we offer custom-designed thermocouples tailored to your specific requirements. Our experienced team works closely with you to develop thermocouples that meet your unique needs, considering factors such as temperature range, probe design, sheath material, insertion length, and termination type.

What lead types are available?

We supply heaters and thermocouples with standard single conductor metal braid, double conductor metal braid, and severe duty flexible armor cable leads. Metal braid leads work well in nominal abrasive environments, while flexible armor cable is recommended for excessive abrasive applications.
