Patent ID: 8006511

Claim:
A fluid vapor distillation apparatus comprising: a source fluid input; an evaporator condenser apparatus comprising: a substantially cylindrical housing; and a plurality of tubes in said housing, whereby said source fluid input is fluidly connected to said evaporator condenser and said evaporator condenser transforms source fluid into steam and transforms compressed steam into product fluid; a heat exchanger fluidly connected to said source fluid input and a product fluid output, said heat exchanger comprising: an outer tube; and at least three inner tubes, wherein said outer tube is a source fluid flow path and said at least one inner tube is a product fluid flow path and wherein said at least three inner tubes are twined to form a substantially helical shape; and a regenerative blower fluidly connected to said evaporator condenser, whereby said regenerative blower conoresses steam, and whereby the compressed steam flows to the evaporative condenser where compressed steam is transformed into product fluid.
