THE CRYSTALMASTER
E N E R G Y S AV I N G E P S O N
EPSON offers effective savings to its customers through a wide range of electronic devices, such as semiconductors, liquid crystal display (LCD) modules, and crystal devices. These savings are achieved through a sophisticated melding of three different efficiency technologies.
Power saving technology provides low power consumption at low voltages.
Space saving technology provides further reductions in product size and weight through super-precise processing and high-density assembly technology.
Time saving technology shortens the time required for design and development on the customer side and shortens delivery times.
Our concept of Energy Saving technology conserves resources
by blending the essence of these three efficiency technologies. The essence of these technologies is represented in each of the products that we provide to our customers.
In the industrial sector, leading priorities include measures to counter the greenhouse effect by reducing CO2, measures to preserve the global environment, and the development of energyefficient products. Environmental problems are of global concern, and although the contribution of energy-saving technology developed by EPSON may appear insignificant, we seek to contribute to the development of energy-saving products by our customers through the utilization of our electronic devices. EPSON is committed to the conservation of energy, both for the sake of people and of the planet on which we live.
WORKING WITH ENVIRONMENTAL ISSUES
In 1988, Seiko Epson led in working to abolish CFCs, and perfect abolition of those ozone layer-destroying substances was achieved in 1992. In 1998, the 10th year of start of the CFC-free activity, Seik.
