At TUTCO-Farnam, the majority of our custom-designed heaters use mica board machined to meet the customer’s specifications.

TUTCO received a unique request from a customer seeking tubular heating elements for electric branding irons designed for wood and leather applications.

TUTCO was approached by a customer with a unique requirement for heaters to be integrated into portable equipment designed for honey harvesting in remote areas where beekeepers manage their hives.

When it comes to describing cartridge heaters, some details can be complex. This article aims to resolve any difficulties you may encounter when describing the length of heaters with elbows, right-angle leads, bushings, or other terminations.

As we study heat transfer and any thermal system, we will need to consider the three types of heat transfer, which are conduction, convection, and radiation.

Typical heaters won’t fare well in a moist environment. They’re not built to withstand water or other liquids. The standard seal on most heaters is porous, and most high-temperature lead wire insulation may actually wick moisture into a heater.

When designing an electric heating system for industrial processes, important factors routinely include required power, location, ducting, air source, and controls, but circuit protection is often overlooked.
