HISTORY

Since global oil pricing has been rising, our company has readjusted the overall energy reduction to make it suitable for the era of high oil prices and we made an effort to develop alternative energy source which is called Ondol heating system. Traditional Ondol is used to heat homes by using hot air coming from the burning wood under the floor. However, a big change occured. Nowadays, we use to electric floor heating system. So it can reduce the Oil price as well as gas heating cost and prevent global warming as it does not generate carbon dioxide. The comfort and warmth that it brings is quite better compared to that of western heating style. Therefore Ondol system became popular throughout the world.Our electric floor heating system offers the affordable luxury of warm floors and barefoot comfort that anyone can enjoy anytime. Also installing is easy so you can place it anywhere you desire for the enjoyment of warm floors.Our floor heating system allows homeowners to enjoy warm temperature with a reduced utility cost and maximized energy efficiency. We, in our company, would like to guarantee that we can meet the standards you have for a heating system.

DW WHAT IS X-L PIPE HEATING SYSTEM?

5 CONDITIONS OF ELECTRIC X-L PIPE HEATING SYSTEM

It is an innovative heating system that uses heat and increased pressure generated by Heat Transfer Medium by heating the sealed X-L PIPE without boiler in which water or other fluid is heated and water circulation motor which pumps water circulated in the PIPE.

Heated electric wires in X-L pipe collect vapors in the upper part of X-L pipe, resulting in internal pressure and unclear boiling when temperature difference between liquid and gas is over 10°C.As a result, internal pressure will be the negative pressure which is lower than atmospheric pressure at room temperature and so, boiling temperature of water will get lower. The temperature of floor will be increased and heat will last longer according to Nucleate Boiling phenomenon. Therefore, this process increases energy efficiency and you can save energy by using this energy saving product. One of the products using this technology is a pressure cooker.It is the innovative high energy efficient floor heating system that has no heat loss and achieves 30°C rise effect in temperature. Our patented pressure absorbing device absorbs too much internal pressure and also the heat transfer medium and carbon tissue absorb the electromagnetic waves for well-being life.

Nucleate Boiling phenomenon : The process of forming steam bubbles within liquid in micro cavities adjacent to the wall if the wall temperature at the heat transfer surface rises above the saturation temperature while the bulk of the liquid is subcooled. The bubbles grow until they reach some critical size, at which point they separate from the wall and are carried into the main fluid stream.

HEATING FILMUSING THE HIGH EFFICIENT RADIANT HEAT

DW WHAT IS DAEWOO HEATING FILM?

DW BENEFITS OF HEATING FILM

DW FEATURES OF HEATING FILM

It is an innovative heating system that is made with gravure printing of heat generating carbon tissue on PET Film and copper busbar. Since it emits far infrared rays and anions, warm radiant heat can be felt for a well-being life.This film is ideal for during the certain time for the sectional space that needs to be heated because it requires a short period of time to make heat so suitable for customer, accommodation, office, church, restaurant, and stairs. For stable use, we recommend you to use the hardwood as the finishing material.If you are using for the linoleum finishing or humid environment, you need to consult with a construction company.

1.Energy can be saved more than 65%.(On regular basis)2.No need space for boiler3.Far infrared radiation (90.3%) and anions (250cc) are emitted to improve

health.4.Don’t worry about smoke, noise, fueling, freezing.5.Convinient control such as sectional heating, central heating and

sectional control.6.One day installation and immediately usable7.Free to choose of finishing materials8.Fast installation without taking off the existing floor9.It can lower the height of ceiling and the weight of building.

1.Burning resist PET application : The ivory PET Film is used the XB-65 with VTH-2 chip in for heatdefying insulation which has the UL Certificate and is manufactured by Doraysaeghan.

2. Gravure printing : As screen printing cannot print carbon tissue evenly, it is inappropriate for the heat generating plate. It can be partially overheated to cause fire and short circuit. We, however, have chosen the gravure rotary printing press to pursue to the safety by giving electric resistance evenly to the Heat Generating Plate.

3. Wide silver space : The silver space is for the space between carbon and copper busbar where theelectrical energy is converted to thermal energy. This space prevent spark, and is important part related to product life and safety. We broadened this space for safety.

4. Copper busbar with 12mm of width and 10amp : Wide copper busbar to restrain overheating. The thinner PET has superior adhesive strength and keeps air cut.
