Abstract: The treatment unit includes an evaporation device including a gas circulation pipe, and a material with a large specific surface filling an evaporation section of the circulation pipe; a device for circulating the gas through the circulation pipe; a liquid impregnating the material with a large specific surface, the liquid containing at least one product or a mixture of volatile biocide and/or phytoprotective products, with a boiling temperature between 130 and 280° C., the material with a large specific surface having a liquid retention capacity greater than 50 L/m3 of material with a large specific surface at 20° C.; a recharging device, arranged to re-impregnate the material with a large specific surface with liquid or to replace the spent material with a large specific surface with a new material with a large specific surface impregnated with liquid.

Abstract: The process includes a treatment step during which a liquid containing a biocidal and/or plant-protection product or a mixture of biocidal and/or plant-protection products is evaporated and injected into the internal atmosphere of premises, the liquid being evaporates at a temperature of less than 50° C., the product vapour concentration in the internal atmosphere of the premises being kept at greater than 10% of a saturation concentration of the vapour of said product in said atmosphere at said temperature for a saturation duration of greater than 12 hours.
