Yu Sun Enterprise (shares) in Taiwan, the major service projects: EPS hygiene utensils, EPE foam packaging materials, high pressure water mist equipment, non-immersion type steam generator equipment.

Since the company's production of plastic products, is flammable high-risk industry, considerable attention for fire safety, that is configured with the existing high standard of fire protection products] [automatic sprinkler system in order to maintain plant safety. However, Yu Shang enterprises (shares) with related industries in view of the company's own fire fighting experience, decided to invest in research and development of more high-end specifications [high pressure water mist fire-fighting equipment cleaning, fire extinguishing system, dual-use]in 2009, and the plant can effectively assist family away from the giant fire disaster, enough to protect the life and property safety;  [when we put on the high-pressure cleaning nozzle device can become a clean environment a weapon, usually can be used for washing, window washing, watering flowers and trees, etc. additional features, usually that is the best use of the training, to break the limitations of traditional firefighting equipment usually can not use, safe] elderly and infirm Jieke easy to use.

Yu Sun Enterprise (shares) the company in early 2014 to use more of the water mist technology, research and development of non-immersion type steam generator (steam Ding), in view of rising fuel prices and the government's strict control of air pollution emissions increase gradually in looking for ways to reduce fuel costs and eco-friendly way, Yushang Gong Division developed a non-immersion type steam generator (steam Ding), not only can save fuel costs, but also reduce carbon emissions, it is the most sensible choice.

[] Water mist system is a new generation of high-tech environmental protection fire protection products, pursuant to the definition of NFPA 750 water mist (Water Mist), the system must be a minimum design pressure of the operation, the nozzle at a distance of 1 meter measured at 99 % by volume droplets diameter (Dv 0.99) should 1000μm or less, and then can be called mist. And to mitigate global warming phenomenon, in 1987 the world's major industrial countries signed the Montreal Protocol (Montreal Protocol) CFC restrictions manufacture, sale and use, Dragon fire extinguishing system in consideration of the environmental issues, has entered into an alternative and suspend the use of (phase out) stage. Water mist fire extinguishing system efficiency is good, and no environmental concerns is an ideal substitute for the Dragon, the fire test to verify the general Class A fires, flammable and combustible liquids, electrical fire extinguishing effect can play, so its wide range of applications.
