Full Product Description
Metzerplas GALI dripper 2 l/h: "Anti-drainage" technology for professional irrigation
Metzerplas GALI is a highly efficient compensated dripper of the external type, developed by Israeli engineers for the most demanding agrotechnical tasks. The main feature of the GALI series is the integrated anti-drainage system (CNL), which turns conventional irrigation into a high-precision moisture management tool.
What is the uniqueness of the anti-drainage function?
Unlike standard emitters, Metzerplas GALI automatically stops the water supply as soon as the pressure in the system drops below 0.2 bar (2 m water column). This provides two critical benefits:
-
Instant start: The tubes remain filled with water after the pump is turned off. The next time it is turned on, irrigation starts simultaneously along the entire length of the line without spending time filling the system with air.
-
Protection against overwetting: In areas with a slope, water does not flow to the lower points under the influence of gravity, which prevents waterlogging of lowlands and insufficient watering on hills.
Technical advantages of the model:
-
Silicone membrane: High-quality silicone guarantees many years of accurate operation of the pressure compensation (PC) mechanism. The flow remains stable (2 l/h) in a wide pressure range.
-
Self-cleaning: The special design of the labyrinth with a wide cross-section creates a turbulent flow that washes away small particles of dirt during each cycle.
-
Compactness: Small dimensions allow easy installation of drippers in the limited space of greenhouses or vertical farms.
Fields of application:
-
Hydroponics and pulse irrigation: Where short irrigation cycles require an instant supply of water.
-
Closed soil and nurseries: Precise dosage for each plant in the pot.
-
Landscapes with complex topography: Irrigation on terraces and slopes without leaks.
Installation recommendations:
It is installed in a "blind" tube (PE) with a diameter of 16–32 mm. The required hole diameter is 2.6–3.0 mm. The recommended level of water filtration is at least 120 mesh.
