The Operating Concept of EWA-III

Stage 1 – Door opens, air blow through and is released dry.

Stage 2 – Door closes, lower blower turns off, heat exchanger valve opens and the chamber    is heated to 85oC, filling with steam

Stage 3 – Steam valve opens and the steam is sucked out by a piston and pressed into the condensation container.

Stage 4 – Steam is condensed in the condensation container and pumped out as water.

Stage 5 – Latent and pressure heat is returned to the heat storage tank.

Stage 6 – Heating and steam valves are closed, followed by door opening.

 

Realizing the limitations of traditional condensation concepts that it applied in its first models, EWA research and development invented a multi-stage, dry, chemically based concept that is unaffected by air pollution and suits most climatic conditions, while directly using thermal energy from almost any source.
