USER BENEFITS OF OUR CARBON EFFICIENT ELECTRIC HEATING ELEMENTS:


The whole surface area of our elements serves as many hundreds of adjacent resistor wires, each conceptually of 100-250 microns ‘diameter’. This is typically between 3x and 7.5x finer than a conventional resistor wire of 0.75mm diameter, which is (of course) a single wire filament.

Accordingly, even allowing for the extra length that coiling a filament wire imparts, our ‘flat’ elements provide many times the effective surface area than do conventional wire elements.

This has relevance not only for the heat transfer efficiency of our elements but also for their safety in use. The current density carried by our large surface area elements is factors fold lower than for a single strand wire. Accidental contact with a live element running at 230/240v is therefore unlikely to prove fatal, which is unlikely to be the case for a single strand wire carrying the same overall current.


This significantly better heat transfer efficiency allows our elements to operate at very significantly lower operating temperatures (compared with traditional elements) to generate the same heating effect.


This extra efficiency derives from the large surface area in intimate contact with the base substrate, plus the low thermal mass and relatively low specific heat of our elements.


Trade press articles have taken the view that energy efficiency improvements with electrical heating systems have now “reached as far as the technology will go”. We do not agree with this view.
