Products

EWA offers two product lines for water supply based on extraction of air humidity.

EWA-AC is based on cooling condensation and combines highly efficient air conditioning and water production.

EWA-III is based on dry desiccation and pressure condensation and is designed for large water volumes.

EWA has established joint ventures with Energreen Power of India in order to combine gasification technologies to supply heat and electricity to large EWA plants.

The gasifires are capable of using any kind of organic matter, including biomass and organic waste, which is converted into hydrogen and then used by electric generators to supply electricity (in addition to the heat energy used by the EWA plant).

A history of innovation and humanitarian effort

The first prototype was developed in 1997 by Etan Bar in cooperation with the World Bank; the venture attempted to provide a solution to the severe water shortage of the Palestinian population in Gaza (the Suitcase model), as well as in West Africa. But the product consumed too much energy and was not economically adapted.
 
The next milestone was the EWA-I - the first model to use the dry desiccant technology - at about the same time as the Asian Tsunami (2004). There were attempts to use it in the disaster areas. Some units were donated to India, but the organization was not suitable to cope with such projects. 
EWA-III combines highly efficient energy conservation with desiccation technology, enabling for the first time sustainable and economical extraction of water from the air – and that while using renewable resources.
