Useful 500w Industrial Immersion Heater Background information.

Industrial Heating elements are a resistance coil wire (producing heat), encased in magnesium oxide (the white powder, compacted by rolling down from 10mm to 8mm, for protection of wire & insulation purposes, bizarrely) encased in a usually stainless steel tube. For more detailed written explanation, click here. For a video explanation by some bloke with a really boring voice, click above.

Just for clarification, an Immersion Heater (see below) is 3 such elements (as image above) on a screwplug with a terminal box housing the connections. Cuz we all speak diffrent!

We can supply Industrial Heating Elements to your exact length, power output and shape requirements, but as dimensions and accuracy are critical, it’s best we have a conversation about your needs. Also, if your 3kW Industrial Immersion Heater needs deviate from the stock heater above, feel free to call Jamie on 01827 215684 to discuss your specific needs.
