Pressure-compensating dripline that holds its flow — uphill, downhill, and underground.
From Gestiriego in Spain — 25+ years of dripper R&D. Prodrip PC for surface runs on difficult ground. Terram Neo for subsurface installs built to last a decade.

Prodrip PC — accuracy on long runs and broken ground.
A flat, pressure-compensating integrated dripper for variable topography and long laterals. The cascade labyrinth keeps water turbulent so particles never settle, and a wide inlet filter plus continuous self-washing between membrane and microchannel keep it from blocking.
Discharge exponent of 0.0 — flow stays even from the first emitter to the last.
Use it for: vineyards, olive groves, citrus and stone fruit, greenhouses, landscape — anywhere with slope, long sides, or uneven ground.

Terram Neo — bury it once, run it for ten years.
A cylindrical pressure-compensating dripper built for subsurface irrigation, with two things most buried dripline doesn't have. A patented anti-root system slow-releases a repellent over a working life of up to ten years, so roots never grow into the emitter.
An anti-siphon mechanism blocks soil from being sucked back in when the system shuts off and the line empties. Self-cleaning on every pressure cycle.
Subsurface delivery puts water and nutrients straight at the root — up to 40% less water than surface irrigation.
Use it for: subsurface installs in vineyards, olives, and orchards; open-field crops needing precise fertigation; long laterals on uneven terrain.
