a revolution in droplet application - nimbus electrodynamic (EHD) technology gives unparalleled control over charged sprays and discharged mists

Nimbus revolutionary electrohydrodynamic EHD spray technology:

When a high voltage is applied to a semi-conducting liquid in a nozzle, the fluid breaks up into equally sized charged droplets whose size can be carefully controlled (down to a few microns.)

Because the droplets are charged they are attracted to earthed objects coating them precisely and evenly. As a result, EHD technology promised to be a disruptor in areas as diverse as environmentally-friendly agricultural sprays, malaria control, knotweed removal and scar-reducing wound care.

Nimbus R&D is a London-based start-up developing proprietary electrohydrodynamic (EHD) technology.

Researchers at Nimbus R&D are building on thirty years of expertise to develop high-voltage technology and semi-conducting fluids for novel ultra-low volume spray systems; the applications range from agriculture and vector control to industrial processing.

Using modern versions of the  Electrodyn agri-sprayer – first developed by ICI/Zeneca – Nimbus revolutionary electrohydrodynamic EHD spray technology aims to transform smallholder agriculture in Sub-Saharan Africa, and provide vital new tools to combat malaria and leishmaniaisis
