For your healthy & energy saving system
DAEWOO ENERTEC

2. GREETINGS!
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.

3. NON-MAGNETIC HEATING CABLE
DW WHAT IS THE NON-MAGNETIC HEATING CABLE?
It is a form of heating system with utilizes heat conduction and radiant heat
for indoor climate control.
Heat can be provided by electric cable instead of boiler or water circulation
motor and its installation is easy. Dry or humid heat as the 21st century
energy efficient heating system delivers to the entire room and the people
without any harmful effects due to 7mm heat conductor, double coated PE
cable, and the electromagnetic wave screen.

4. ELECTRIC X-L PIPE HEATING SYSTEM
DW WHAT IS 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.

6. HEATING FILM
USING THE HIGH EFFICIENT RADIANT HEAT
DW WHAT IS DAEWOO 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.
DW BENEFITS OF HEATING FILM
1.Energy can be saved more than 65%.(On regular basis)
2.No need space for boiler
3.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 usable
7.Free to choose of finishing materials
8.Fast installation without taking off the existing floor
9.It can lower the height of ceiling and the weight of building.
DW FEATURES OF HEATING FILM
1.Burning resist PET application : The ivory PET Film is used the XB-65 with VTH-2 chip in for heat
defying 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 the
electrical 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.
