The 3-phase systems are called 3-phase delta and 3-phase wye and this document will explain how to connect your single phase heaters to such a system, and how to check that it’s done correctly.

Grounding a device generally serves two purposes. The first is to provide a safe path for current flow in the event of a short circuit. The second is to provide a true “zero voltage” reference for the circuit.

An automotive customer had an issue with a heater they were using in a curing oven where the application required using a liquid mist on a new material they were curing.

Like their band heater counterparts, HT Mica Strip Heaters can handle temperatures up to 900°F (482°C) and are designed for demanding applications across multiple industries.

When you need to determine the wattage required to heat an application, there are a few quick ways to determine the wattage requirement for different scenarios.

A company needed a tubular heater to use in an aluminum extruder barrel to keep the aluminum soft enough to press and extrude but not hot enough to make the aluminum a molten liquid.

A diode in series with the heating element will reduce the applied energy to the heater for a given voltage and allow a larger lower resistance heating element to be used.
