ET Nano infrared electric heating ring is an auxiliary heating device for plastics and rubber machinery,
which is independently developed by ET. It adopts a new type of nano infrared heating element with
thermoelectric conversion efficiency up to above 99.8%. And it adopts infrared mono-direction radiation
as conduction way, which greatly improves heat transfer efficiency between heating elements and stuff
canister. The heating ring adopts aerogel felt with heat transfer coefficient as low as 0.013w/m.K to ensure the surface temperature of heating ring does not exceed 70℃. Its three generation of thermal radiation protection coating ensures the surface temperature of the ring as low as 50℃, which helps improve the fatal disadvantage of conventional heating rings such as low thermoelectric conversion efficiency, low heating efficiency, high surface temperature, so the heating ring not only helps achieve energy conservation of more than 30%, but improve the operating environment of the workshops.
