A Hong Kong company is at the heart of technological revolutions that can keep you warm and your wine cool while saving energy. Aoyagi Electronic Industries will be exhibiting far infrared ray (FIR) heating elements and products at the electronics fair along with an eco-friendly absorption refrigerator. Although FIR technology has been used for many years as a means of heating and drying in industrial processes, it is being developed in a variety of ways, both in industry and household appliances. It is expected to gain greater recognition for saving energy and for its contribution to a healthier and more comfortable living environment. Aoyagi Electronic Industries, established in 2001, is part of Japan's Aoyagi Corporation. Its head office is in Kowloon and it has a factory in Shenzhen, employing more than 500 people. Crimson Chan, the firm's executive director, said the electronics fair would be a chance for the company to promote FIR technology, which is booming in Japan. 'FIR technology is ecologically and environmentally friendly, causing less pollution, energy savings and improved health and safety,' he said. 'We are using the fair to promote FIR technology and, hopefully, to get sales. The worldwide demand for this technology depends on consumer knowledge and how it is marketed.' The Japan Far Infrared Rays Association was formed in 1992 to promote the technology. A Hong Kong association co-operates with the Japanese body and other overseas organisations in educating the public about the technology. Since far infrared rays are easily absorbed by a wide range of materials, a high percentage of energy transfer is performed through the radiation mechanism. This makes this form of heating more efficient and clean than some other types. Aoyagi's patented waterproof FIR heater can be applied to steamers, garments, gloves and even pet warmers. As humans are made up of 70 per cent water, the rays can stimulate blood circulation to improve immunity and metabolism. The company's absorption refrigerator has no compressor and uses no chlorofluorocarbons that damage the ozone layer. It is silent, saves energy and can even be powered by a car battery for use at barbecues or picnics. Mr Chan will speak at conferences at the electronics fair on Wednesday and Thursday about FIR product markets and business opportunities.
