RWS Robert Wilson Services
About Us Wilson Group interests have a long and proud tradition of exporting and importing primary produce and commodity products dating back to as early as 1861. Initially founded to supply the demand for equipment and services to New Zealand’s gold rush in the mid-1800s, as fourth generation, Robert Wilson was one of the pioneers of the venison industry in New Zealand and an innovator in a range of primary produce export markets including timber, seafood, lamb and wool to name a few. Over the last 50 years, the Wilson Group has been instrumental in the export of over 1 billion dollars of primary produce from New Zealand to export markets around the world. Today RWS continues this proud tradition, exporting sawn timber to Asian markets from both New Zealand and Australia, operating import divisions for Home & Building as well as Farm & Steel products, and proudly representing the world’s largest Solar manufacturer through its Solar Heating division. Our partner company RWL continues to manage exports of seafood, fruit and vegetables,
commodity and dairy products into Asian markets. After many years doing business in China and Japan, RWS enjoys working with a wide network of partner businesses and contacts in Asia, and has offices in Shanghai and Tianjin servicing the growing timber market, managing factory relationships and working to find markets for select NZ made products. As the world becomes ever more conscious of the environment, and demand grows for natural and renewable products, New Zealand is set to benefit from its market position and ability to offer higher quality, eco-friendly options. Likewise, as alternatives like solar energy gather momentum as smart and viable options for consumers, RWS is well positioned to offer innovative solutions for heating and power as we look to the future. RWS Head Office is situated in the lakeside town of Wanaka in New Zealand’s pristine Southern Lakes Region, and while our network and regional offices reach around the world, we are proud to call New Zealand home.

How It Works Himin Evacuated Tube As the main component of a solar water heater, the all glass evacuated tube is built like a thermos bottle, with a vacuum between the inner and outer tube. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating which features excellent solar radiation absorption and minimal emittance.
Covering an area of 42,800 square meters (462,000 square feet), the Himin evacuated tube factory is one of the world’s largest manufacturing sites for evacuated tubes. The first automated coating line ensures high quality and consistency of solar evacuated tubes. Himin evacuated tubes with high efficiency in absorbing heat can be widely used in areas with high temperature and freezing areas - these patented tubes pioneer a new era of solar-thermal utilization. The invention of Himin UTLE (Ultra low emission) evacuated tubes is an important breakthrough of world solar technologies. These tubes feature ultra low emission with an absorption of 93% and an emittance of 4%. These tubes are tested in the destructively cold environment at the South Pole where heat loss is an important parameter.

Heat Pipe Collector Sunlight is captured by the coated vacuum tubes which absorb the radiation as heat and conduct it through aluminium fins to the heat pipes. The liquid inside the heat pipes vaporizes as it is heated and the vapour rapidly rises to the condenser (top), releasing the latent heat, and condenses to form a liquid and returns to the pipe bottom where is evaporated once more and repeats the cycle. A manifold on the top of the solar collector allows a working fluid (typically anti-freeze) to absorb the heat from the top of each pipe. The working fluid is pumped through the manifold and then through an external heat exchanger which transfers the heat to water in a pressurized storage tank. Brief Introduction The characteristic of vacuum solar collectors is that they have a higher efficiency level in autumn, winter and spring than standard flat surface collectors; the efficiency of these collectors is lower than flat surface system in summer. Vacuum collectors are particularly suitable to be integrated with low temperature room central heating like wall or floor systems or also for high temperature. The characteristic of vacuum solar collectors is that they are made of vacuum glass tubes with a high efficiency selective coating; the central part of these tubes is entirely made of copper. The basic characteristic of these panels is that they have a curved transparent absorbent surface that allows collectors that are not positioned perfectly towards north to offer the same results as if they were. Heat pipe solar collector adopts the interferential coating technology for a high-efficiency absorbing layer, with features of resisting high-temperature and high-coldness and high efficiency in absorbing energy. The inner part adopts the heat pipe structure, thus there is no water in the tube and there is no scale which avoids the breaking of the tube, extending the life span. Working Principle Vacuum tubes absorb and convert the sunlight into heat energy which is then transferred to the heat pipe by fins and then the medium dissipates the heat at the cooling end of the tube, exchanging heat with the medium in the inner vessel. In this way, it heats the cool water into hot water gradually. Continued over page.

Commercial Systems: Manifold Solar Collector and Hot Water Project A solar collector project is an installation comprised of a large number of solar collectors which is generally used for a factory, a hotel, an office building, or swimming pool. The non-pressurized system is simpler and more economical than the pressurized system and it is applicable in those cases where it is permissible for the water which goes through the solar collectors to circulate through the storage tank or the swimming pool. Project water systems are always custom-designed for each specific installation.
12
Features: » The non-pressurized solar water heating project supply of hot water is managed by an intelligent controller which takes care of automatic water filling, circulation controlled by temperature differences, supplemental heat as needed to prevent freezing, circulating of water as needed to prevent freezing, circulating of water through the pipeline and auxiliary electric or gas boost heating when needed; » With the sun providing most of the heat energy, up to 80% of the needed energy can come from the sun, resulting of course in 80% fuel cost saving; » Less consumption of fuel reduces emission of greenhouse gas, so the system is environmentally friendly; » The combination of solar and auxiliary heat will supply hot water 24/7 independent of weather conditions; » The optimal design of the collector makes it visually less obtrusive and compatible with existing architectural designs.
