What Is Graphene?
Graphene is the future of nanotechnology. It was first isolated in 2004 by two researchers Prof Andre Geim and Prof Kostya Novoselov at The University of Manchester. Graphene is the world’s first 2d material consisting of a single layer of carbon atoms connected in a hexagonal pattern. It is extremely thin, lightweight, stronger than steel with excellence current density and thermal conductivity. These superlative properties are being exploited by industries to enhance existing materials and transform future technologies.
FAR Infrared Rays
FAR Infrared radiation (FIR), or infrared light, is a type of radiant energy that is invisible to the human eye but can be felt as a gentle source of heat. FAR Infrared Rays (FIR) are the longest rays within the infrared spectrum, founded in 1800 by William Herschel, and the most beneficial to life on the planet. These rays penetrate deeply into our bodies helping to make us feel warm and energised. This energy is essential for all living things and one of the major sources of these non-harmful rays comes from exposure to FIR from the sun. With the increase of global pollution, and other contributory factors, the opportunity to benefit from vital life enhancing rays is diminishing and contributes to poor health and many diseases. Ongoing scientific and medical research into the benefits of FAR Infrared are driving industries to develop new innovative ways to utilise these benefits within a range of integrated products and alternative medical therapies.
FAR Infrared Radiant Heat
FAR Infrared radiant heat, in its simplest form, is the planet’s oldest form of heating. It utilises invisible electromagnetic infrared waves to heat solid objects, and the best way to illustrate this is how the sun heats the earth. When these rays are absorbed, they heat the object up and this is then radiated out. Radiant heat which utilises FAR Infrared Rays gives the same comfort feeling that our bodies associate with sunshine and is not relative to ambient air temperatures. Radiant heating, utilising FIR, provides a better solution for use in buildings and products. However, not all radiant heating products offer the same benefits, the higher the product surface temperature the less the benefits of FAR Infrared comfort are felt.
Why Is NexGen Low Voltage?
The mechanism for converting electrical energy into heat for carbon based heating is mainly the collision of charged particles in the electric field. The performance of the heater or heating film is directly affected by the current and intrinsic resistance of the electro thermal materials. Graphene’s very high current density and thermal conductivity guarantees faster temperature responses and uniform distribution, essential for optimum performance to ensure no overheating or hot spots. NexGen covers 95% of the area with its graphite and graphene mix. In comparison, on average, FAR Infrared and Wire Mats cover 2% to 4%, Carbon Film 60% and Infrared Panels 2%.
Voltage squared divided by resistance equals power which is measured in watts. Resistance is exactly as it sounds, to stop or resist flow from one thing to another. In this instance we are using heat. The higher the resistance the more power required. Most carbon films or heating cables average 60 to 80 ohms resistance across a 60cm sheet. In comparison NexGen heating films average between 4 to 12 ohms across a 60cm sheet. The difference in resistance illustrates why we reach required temperatures using a low voltage power supply.
24×24/60 = 9.6 watts
24×24/4 = 144 watts
That’s 93.4% more power!
