High Watt Density Industrial Cartridge Heaters
Heatingelementsinc‘s high watt density cartridge heaters are built with premium materials to maximize field performance. Our cartridge heaters can be configured with optional type J or K thermocouples. Heatingelementsinc is also able to manufacture metric sizes from 3.1 mm to 25 mm and imperial sizes ranging from 1/8” to 1”. If you need a quality built industrial cartridge heater designed to your specifications and delivered fast, Heatingelementsinc has the right high watt density cartridge heater solution for you.
No new technology has been able to surpass the cartridge heater with respect to performance, durability, and value heating an object from the inside out. Heatingelementsinc can help you with your New product development, solving a cartridge heater problem, or just getting you a replacement heater.
New Product Development
At the early stage of new product development, utilizing a cartridge heater, details can be overlooked. Heatingelementsinc can provide performance driven engineering consultation that will help determine heater fit, electric heater location, heat distribution, thermocouple location, and key thermal mass positioning. Too often heater placement is determined too late in the design process – creating difficult to solve heat profile problems. Addressing key thermal strategy elements early will enable design engineers to better optimize performance and responsiveness of the heated object.

Solving a Cartridge Heater Problem
Heatingelementsinc can work with you to improve the durability and performance of your heater.
Do your failed cartridge heaters have similar characteristics? If so they hold clues as to the root cause of failure. Heatingelementsinc can evaluate your failed heater and identify the right configuration to improve durability.
Have you noticed a variation in quality in your plastic processing, packing, rubber molding, mass spectrometry, analytical equipment or other application? Nexthermal can offer heating elements applications specific wattage distribution profiles that can improve throughput, quality, and speed.
Replacement Heater
Heatingelementsinc high watt density cartridge heaters set the standard for responsiveness, precision of OD sheath tolerance, durability, and versatility.
The Shenzhen Xinshengfa Electrical Heating Tech Co., Ltd cartridge heater configurator puts the engineering tools in your hands to design the correct cartridge heater for you application specific needs. This program guides, and informs you on design criteria with an easy to use graphical interface. In less than 2 minutes you can engineer your heater.
