Terronics Electrostatic Sprayers are equipped with ElectroHydroDynamic (EHD) atomisation nozzles. The EHD atomisation nozzles rely solely on electrostatic forces for droplet formation. No mechanical moving nozzle parts that wear out, nor high pressures producing turbulences and drifting airborne droplets.

Through over 20 years of nozzle refinement, Terronics has various EHD nozzle designs available for specific coating needs. The patented EHD nozzles dispense jets in the stable Taylor cone mode and these jets break up in droplets of uniform size. This diffuse spray cloud is attracted to and deposited onto your product, in a special designed and engineered Terronics coating chamber, at transfer efficiencies close to 100%.

Single Dart Nozzles have been developed to completely eliminate the erratic and unreliable behaviour of the well known laboratory “needle” nozzles. A single spray plume is produced for applying highly accurate and precise coatings on small objects like medical implants. Nozzle flow rate can be as low as 0.005 ml/hr and as high as 60 ml/hr.
