Abstract: A device for preparing an aqueous solution of calcium chloride, particularly for use as a surface deicer, comprising a containment tank which defines a body for containing the water in which the calcium chloride in solid form is to be dissolved and at least one fill opening for the calcium chloride in solid form, elements for mixing the water with the calcium chloride in solid form in order to obtain a solution of water and calcium chloride; the mixing elements comprise means for the forced circulation of the fluid contained in the containment body within the containment tank. It is also disclosed a device for distributing an aqueous solution for use as a surface deicer comprising a plurality of straight jet nozzles designed to direct, toward the surface onto which said aqueous solution is to be spread, a respective jet designed to strike a substantially point-like region of the ground.
