Rexva XiCA Carbon Film (Sauna Heating Film)

Overview of Xica Heating Film

XICA Heating Film is the most advanced face-shape far-infrared heating element unit which is made through the following processes of 1)applying carbon heating element to base film, 2)putting a thin coating made with activated carbon to absorb pollutants, 3)creating electrode with copper foil, 4)lastly making laminating process with film made from PET material.

Unlike regular heaters, carbon heating element are coated on the entire film which enables them to emit far-infrared radiation evenly. This is beneficial to your health making you feel the warmth of sunshine.
And also the exterior material of film heater is special fabric made of PET material and processed with special waterproof coating to avoid contacts with air, and thus the XICA Heating Film is a future-oriented heating material for wall, ceiling, and floor to be semi-permanently used.
The performance of heating film is dependant on the nano-particle dispersion technology made by cohesion and resistance of silver particles.

Structure of Xica Heating Film

Effect of Xica Heating Film

1. Far-infrared radiation heating
   - rapid heating.
   - keeps room evenly warm without any difference in room temperature between upper and lower part of the room.
   - makes you enjoy comfortable heating effect even in a relatively low temperature of the room compared to convector.
2. Simple installation and easy workability
   - Installation is much simpler than the wet mortar construction method.
   - Installation can be completed simply by installing it between the insulation and the floor finish.
   (* Be sure to install after taking the required heating film installation training course.)
3. Excellent durability
   - It can be used semi-permanently.
   - Its simple structure causes fewer failures.
4. Heating method without combustion.
   - As a heating method without flames, it does not generate carbon monoxide, dust, and combustion noise.
   - Good for facilities to be used by children, the elderly, and patients.
   (kindergarten, nursery, senior's house, hospital, and so on.)
5. Quiet and clean heating.
   - Heat generated by carbon emits a large amount of negative ions and far-infrared radiation.
   - Far-infrared ray/negative ion : remove smell in the room and are very beneficial to the human body and create comfortable indoor air.
6. Excellent economical heating system.
   - Cheaper by over 30% than electric heating and by over 60% than oil boiler.
   - Construction can be completed within a very short time, Which reduces construction costs.
   - Its area heating feature helps you save energy.
   - Possible to be installed with an automatic control (central control) system.

Specification of Xica Heating Film

1) Available to meet order production with individual specification after considering safety of heating film.
2) Available to produce tin-plated booth bar to improve conductivity and to prevent oxidation.

Carbon Black of Xica Heating Film

Carbon black is a material containing carbon(C) like diamond as its main element is used for car, ink, and cosmetics. Depending on carbon's heat treatment temperature, we call it carbon fiber when performing heat-treatment at the temperature range of 1,000-3,000°C and graphite fiber when performing heat-treatment at the temperature of over 2,500°C.
Comparing with other materials, graphite has a very high heat resistance and a very low coefficient of thermal expansion and thus has an excellent thermal conduction and electrical conduction. As a result, this material is the most widely used for electrical heating element units.

* You can control adhesive force and resistance value depending on the mix ratio of carbon and graphite on carbon heating element band of heating film. (This is to use properties of circular molecular structure of carbon and planar structure of graphite.)

Silver Paste
- As a low-temperature type conductive for face-shape heating element, the conductive silver paste of XICA heating film possesses high conductive, characteristics of screen printing, flexibility, and also has excellent adhesion with P.E.T and Laminex.

Insulating Film Material of Xica Heating Film

* Be sure to use material for electricity and electronics for the material for film heating.

Durability Test of Xica Heating Film

• Experimental Institute : US AIC TECHNICA
• Experimental Period : April 25~May 22, 2009.
• Experimenter : Dr.Martin Peacoak (Director of Biotechnology and Materials Science)

Test 1. Conduct of Durability Test for Overvoltage and Over Heating

Durability test conducted by supplying voltage of 480v (exceeding designed power consumption by 23 times)to XICA Heating Film designed for 110V AC for about 30 minutes.

XICA 205e model (designed power consumption 400W/m2 ) Used film heater for high temperature to generate high heat.	after 10 minutes(film surface temperature 148.9°C, The film begins transformation and generates bubbles.)
after 17 minutes (film surface temperature 165.5°C, wrinkles on the film surface occur and spread out.)	after 23minutes (film surface temperature 171.1°C, The film starts to shrink.)

* XICA Heating Film has passed the durability test for sales in U.S. market by enduring the voltage of 480V (exceeding designed power consumption by 23 times) for 30 minutes and demonstrating heat-resisting force of about 170°C in above experiment.

Test 2. Test for Estimating Product Life Span

Check surface cracks of carbon heating element after testing repeatedly the following experiment for 24hours :

• Operate XICA Heating Film for 20minutes,
• Keep its film surface temperature at 40.5°C,
• Lower its film surface temperature to 0°C through the power block and rapid cooling.

How to Choose a High Quality Heating Film

Precaution of Installation

1. Clean the floor of the construction site before installing. Even the floor in order to prevent the heating film from bending or curving.
2. Eliminate construction site's all moisture and dampness in order to prevent them from touching the film.
3. Do not use glass fiber or heat insulator with ragged surface to prevent the damage on film's surface.
4. Be careful neither to damage the surface of film nor step on it when installing them.
5. For finish material, do not use paints that changes color or makes cracks when heated, coloring agents or hardening adhesives.
6. Consult with specialist or construction contractor when installing heat insulator or finishing materials in order to maximize the heating efficiency.
7. When cutting the film, make sure that length of the film do not exceed specified capacity of power consumption(Watt) and thermostat.
   * Formula : Watt = V²R (V=Voltage, R=Resistance)
8. Consult with construction specialist or construction contractor for each construction site when installing other kinds of films.
9. Please add 20% to the minimum expected heat rate when installing after considering various external environments, uses, and other environmental conditions.
