Driplines with mini PC anti-siphon drippers

Designed for subsurface drip irrigation (SDI)

Assif

Assif is a compact, integral, pressure-compensated, anti-siphon dripper specifically designed for subsurface drip irrigation (SDI) applications. Assif driplines anti-siphon feature prevents the suction of sand and soil into the dripper, making it suitable for subsurface drip irrigation in challenging topographies and soil conditions. The Assif dripline has consistently proven to be the most reliable and cost-effective solution for subsurface irrigation of permanent crops in challenging topographies, varying water qualities, and diverse soil conditions.

Fully Automated subsurface drip Irrigation

A 398-hectare subsurface drip irrigation project, commissioned in 2022, brought cutting-edge automation and engineering to open-field farming in Ukraine. Designed across eight irregular fields, the system integrates advanced pumping, filtration, fertigation, and control technologies—delivering efficient, long-term irrigation performance once reserved for greenhouses, now applied to corn and soy.
