Conductive
Standard Cartridge Heaters
TUTCO Standard Cartridge Heaters are designed as an economical quality heater for lower temperature use (typically 45 Watts/in²), depending on the application. They are made to temperatures up to 1000ºF (538ºC) and feature a stainless steel sheath for resistance to oxidation. High purity magnesium oxide (MgO) fills any space surrounding the resistance wire in order to optimize heat transfer and increase the life of the heater. Like Hi-Temp Cartridge heaters, many options are available to customize your heater.

Heat Transfer
Thermodynamics, specifically heat transfer, is used throughout our daily lives, but not always thought of. A common practice of cooking breakfast would be one simple example. You place one type of media, your frying pan, onto a hot surface and apply the “heat”, which is your source of energy, to cook the food. The heat […]
Customize Your Cartridge Heater
Customize for a Competitive Edge Electric heaters come in all shapes and sizes. One of the most popular is the cartridge heater, which can be described generically as a round tube with leads exiting typically at one end that, when attached to an electrical source, produces heat. Selecting a cartridge heater is no different than selecting […]
Cartridge Heaters: Heater and Hole Fit
Cartridge Heaters can be a great choice for many applications that require heat. If used and controlled properly, cartridge heaters can provide a long-term solution for many conductive process heating applications. When using a cartridge heater for your application, there are two key factors to ensure optimal results: Make sure the heater is sized correctly […]
Cartridge Heaters: Heating Liquids
In this article, we discuss heating liquids and the wattage requirements for heating various materials. If used and controlled properly, cartridge heaters can provide a long-term solution for many conductive process heating applications. Make sure that the heater will always be surrounded by the liquid you are heating. The liquid acts as the heat sink […]
Cartridge Heaters: Minimizing Failures
There are several bad things you can do to a cartridge heater (any heater actually) that may damage it or shorten its life. In this installment of Ask Ian, we look at heater abuse and things to avoid. Don’t let contamination get onto a heater, especially near the lead-wires or screw terminals. Even a dry […]
Increasing Conductive Heater Element Life
Does continuous operation shorten heater element life? It’s a common question, and frankly, the answer is yes. All heating wire will eventually fail over time, but it is possible to improve the life of the heater by following these recommendations. All heater types require a balance of cooling and voltage control to avoid overshoot failures. […]
