Reldair Pro-line System

This is the proven and well-known 120 bar system which is used in greenhouses and other applica ons all over the world. This system is praised because of the small droplet size and precise droplet distribu on, where the droplets are equally distributed in the air and do not fall on your precious owers or crops.

Reldair Horti-line System

This system combines the e ec ve nozzle from the pro-line system with the easy to assemble hor -line tubing system. At an opera on pressure of 100 bar this unique system delivers a very high price value ratio.

Water quality

The water quality in the Netherlands varies enormously per region. Moreover, different types of water are used alongside each other in horticulture. These types of water have different pH values (acidity). Crystals can sometimes adhere to the inside of the nozzle because of a high pH value, iron and/or lime scale. This will, in exceptional situations, have an impact on the nozzle's spraying pattern.

Optimal functioning

In order to have the Reldair misting system perform properly, the outlet water must be of a constant quality. Based on our experience, we will provide advice about the applicable techniques or calculate the required prefiltration.
