Electric radiant heating system in multi-layer textile
The Energy Textile (ET) sector produces and markets technologically innovative heating textiles which generate energy-efficient and cost-effective heat thanks to the combination of textile materials, constructions and finishing treatments using electricity.
After a three-years-long research, Cofilea has launched ET-1000, an eco-sustainable multilayer technical fabric, which generates thermal energy, i.e. heat with electricity by means of the Joule effect.
ET-1000 has got the National Patent, released by the Italian Patent Office, it has been also internationally patented by European Patent Office, by United States Patent and Trademark Office and by The State Intellectual Property Office of People’s Republic of China.
Applications for an extension of the patent are in progress in many countries around the world. During its development, great attention was paid not only to the selection of the textile yarn, which allows the transformation of energy into heat, but also to the choice of the materials which form the layers of electrical insulation, heat transmittance and heat reflectance.
This electrical radiant heating system can standardize and direct heat through a nano-technological layer of heat-reflecting material.
Its main features:
low energy consumption
small thickness
reduced weight
flexibility and versatility
That, combined with minimal noise, reliability, safety and savings resulting from its use, make it a unique product of its kind.
ET-1000 can be used in many sectors; today its innovative qualities are better exploited in the branch of industry, of buildings and agriculture
The fabric can be supplied both with alternating current and direct current and different tensions can be applied starting from 6 volts up to 230 volts.
The main characteristic of ET-1000 is its versatility, since the desired temperatures can be obtained by modifying various parameters: the applied tensions and currents, the fabric length, the length of the carbon coil, since ET-1000 is normally produced in 5 different versions of carbon coils.
Special versions of ET-1000 for particular applications can be produced on request, in accordance with the technical principles on which the product is based.
Structure of the product:
- in the upper part there are layers with different functions of electrical isolation and horizontal thermal diffusion, in order to obtain homogeneous heat transmitted towards the outside;
- the inside contains the layer of heating fabric;
- in the lower part various layers have different functions of thermal and electrical isolation, besides that of heat refraction.
Patent
In 2014, Cofilea filed international patent applications for the ET-1000 fabric and the product received wide recognition of the remarkable innovative aspects in three continents as demonstrated by the invention patents that were issued to it.
In 2017, the “European Patent Office” granted the European Patent: EP 3066887, in 2018 the “United States Patent and Trademark Office” issued the US Patent: US 9,883,550 and finally in 2019 “The State Intellectual Property Office of People’s Republic of China “has issued the Chinese Patent: CN 105706525.
The aforementioned awards, in addition to being a reason for wide satisfaction for the company team, confirm the innovative characteristics of the ET-1000 fabric and highlight the versatility of the product for use in a wide range of applications.
