Delavan distributor Germany – spray nozzles for process and agriculture
VIPTech GmbH is a Delavan distributor Germany and supplies plant builders, furnace manufacturers, agricultural OEMs and maintenance teams with full-cone nozzles, hollow-cone and flat-fan nozzles; for cleaning tasks solid-stream nozzles and tank cleaning nozzles complete the range. Delavan nozzles are a benchmark for reproducible droplet spectra – critical wherever defined wetting, cooling or combustion is required.
What matters when selecting a nozzle
- Spray pattern: full cone for area wetting, hollow cone for fine atomisation, flat fan for webs and rows
- Flow and pressure: the characteristic is not linear – flow rises with the square root of pressure
- Droplet size: fine droplets cool better but drift more strongly
- Material: brass, stainless steel 1.4404, Hastelloy or ceramic depending on abrasion and chemistry
In practice the degree of overlap of the spray cones determines uniformity. For axially fed applications axial full-cone nozzles are the first choice. We calculate nozzle spacing from spray angle and target distance and design boom pitch so that adjacent cones overlap by roughly 30 %.
Detect wear before it gets expensive
A worn nozzle delivers more volume at the same pressure and produces a distorted pattern. Rule of thumb: if flow rises by more than 10 % compared with the new condition, replacement is due. The extra medium consumed usually pays for a new nozzle within a few weeks.
Nozzles are the cheapest component in a plant, yet they define product quality – saving here means paying twice in media consumption.VIPTech spray technology
