Nimbus EHD (ElectroHydroDynamic) spray is a form of electrospray – the name given to a certain kind of aerosol that is formed when electricity is used to disperse a liquid. High voltage is applied to a liquid supplied through an emitter. The liquid reaching the tip forms a Taylor cone, which emits a liquid jet. The surface of the jet breaks down to form small and highly charged liquid droplets, which are dispersed due to Coulomb repulsion.
– EHD droplets are uniform at the desired size, typically somewhere between 10 and100 microns (but can be smaller)
– EHD spray is able to cover target surfaces evenly due to mutual repulsion of each droplet
– EHD spray is capable of wrapping around the surface to cover both sides
One of the key features of the Electrodyn system was the use of low-cost carbon-impregnated conducting plastics to make a combined bottle/nozzle (Bozzle).The use of a pre-filled unit meant there was no need for the user to ever handle chemicals.
