Adjustable High Flow Dripper 0-70 L/H for Micro Irrigation

Adjustable high flow dripper 0-70 L/H for micro irrigation (Reference: 101103) by Abrisa represents the ideal solution for precise and economical watering. This high-performance dripper combines advanced technology and ease of use to meet the requirements of amateur gardeners and horticulture professionals.

Applications and benefits of the adjustable dripper

This adjustable dripper adapts perfectly to a multitude of micro irrigation applications. For home users, it excels at automated watering of potted plants, window boxes on terraces and balconies, enabling precise watering even during absences. For professionals, it meets the needs of nurserymen, market gardeners and horticulturists seeking uniform irrigation for their specialised crops.

The flow rate adjustment capability from 0 to 70 litres per hour allows water input to be adapted to the specific needs of each plant species. Water-hungry plants such as tomatoes or cucumbers will benefit from the maximum flow rate, while succulent or Mediterranean plants will manage with a reduced supply. This modularity ensures substantial water savings while optimising plant growth.

Technical specifications and innovation

The Abrisa dripper is manufactured from polypropylene (PP), a material recognised for its resistance to UV, chemicals and thermal variations. Its compact dimensions of 25 x 15 mm facilitate integration into all existing systems without excessive bulk.

The optimal working pressure of 1.5 to 4 kg ensures stable operation in the majority of domestic and professional installations. This pressure range allows use with standard surface pumps or elevated gravity systems.

The major innovation lies in its red screw adjustment mechanism. This patented design allows precise flow rate adjustment by simple rotation, offering intuitive graduation for millimetre-precise dosing. The integrated self-cleaning system prevents particle accumulation and ensures long-lasting operation without frequent maintenance.

Installation and practical use

Installing the Abrisa adjustable dripper is carried out in a few simple steps. Hole punching: Make a 4 mm diameter hole in your micro irrigation pipe using a suitable punch. Insertion: Firmly push the dripper in up to the stop to ensure a watertight seal. Adjustment: Turn the red screw clockwise to increase the flow rate, anticlockwise to decrease it.

For optimal use, position the dripper as close as possible to the base of the plant, thus avoiding excessive evaporation and promoting direct root absorption. On sloping ground, install the drippers upstream to compensate for pressure variations.

Maintenance is limited to a monthly visual check of the flow rate. In the event of partial blockage, the self-cleaning system automatically handles unblocking. For manual cleaning, remove the dripper and rinse it under running water with pressure.

Expert tips and system optimisation

To maximise the efficiency of your installation, pair the adjustable dripper with a watering timer such as Gardena or similar. This combination enables automated watering adapted to the circadian cycles of plants. Programme short but frequent sessions rather than a single heavy weekly watering.

In professional cultivation, integrate these drippers into a fertigation system to combine irrigation and fertilisation. Their compatibility with soluble liquid fertilisers optimises plant nutrition while reducing labour.

Seasonal tip: During winter, completely drain the circuit to avoid frost damage. In spring, check the calibration of each dripper before the start of the growing season.

For sensitive crops such as orchids or bonsai, start at the minimum flow rate and gradually increase according to the plant''s response. This preventive approach avoids water stress and promotes harmonious development.
