(www.bar-pm.com).The company was established in order to execute the business potential of the innovative concepts andtechnologies for plants, devices, systems and large-scale water production apparatuses to supply highquality water from air humidity. EWA Tech is the sole owner of all intellectual properties. Besides watertechnologies, EWA Tech deals with additional environmental related technologies, mainly in the field ofrenewable energy.Year of establishment: 2006No. of employees: 12Background of the companyBar project Management is the founder major shareholder of EWA Tech. The remaining shares are beingheld by Stratum Wealth Management LLC, Florida, USA and its clients. The inventor and CEO of thecompany is Dr. Etan Bar. The company own 2 R&D sites, one in Israel and one in Cyprus, and interestoffices in Ivory Coast and Jordan. The company also established strategic J&V with Proplan Ltd. (Cyprus),Aly Tech (Australia) and Energreen Power Limited (india)Technologies & productsGeneral description:Extraction of water from air- EWA (Extraction of Water from Air) is unique patented technology (patentapplication PCT/IL2008/000397) developed by EWA Tech Ltd. Based on the EWA technology, theCompany developed and produces various apparatuses and water production plants in various capacities,from few liters and up to hundreds of cubic meter of water per day. The EWA technology combinedadsorption with solid desiccants and condensation with capability to recover and return more than 85%percents of the energy invested for the water production. The EWA technology was developed to beeffective almost at any RH, by using all kind of energy sources, including renewable energy sources.Solar Power A/C- EWA Tech’s solar air-conditioner (SAC) is based on basic physical processes, makinguse of solar heat as driving force, while electric power is not required. The key for the EWA Tech’spatented SAC (patent application WO/2008/114266) is in its sophisticated sun-collector capable to collectand accumulate solar energy and transform the heat energy to effective and efficient cooling. A granularsolid material, located in the solar heat collector, interact with a water solution, that being forced toevaporated, and thereby cool the liquid phase located in a radiator that acts as heat exchanger. The solarcollector can accumulate solar heat and utilize it for cooling, even after 8 dark hours. A solar adsorber of1 square meter is capable to collect sufficient solar energy to maintain temperature of 22-24 0 C in spaceof about 40-20m2 (equivalent to about 10, 000BTU). EWA Tech developed two optional SAC systems;passive and dynamic, the first for solar cooling and the second for domestic A/C. EWA Tech is developinga new model of SAC in which that water solution is being replaced with organic solvent.Function of the product(s):Water supply independent on infrastructure• Solar power cooling and air conditionObjectives / Target companiesProduction R&D Distribution.Back to Index15
