STARDROP

STARDROP drip irrigation tape:

Suitable for above and under ground applications.
Seamless construction allows to endure pressure fluctuations.
Two parallel lines – quality symbol – help to install the tape in the correct upward position.
Produced of a special mixture of high quality polymer materials that assures maximum uniformity of wall thickness and high durability even for the thinnest tape.
Produced with the up-to-date technologies and advanced equipment at in line continuous quality control.
Labyrinth design of the emitter ensures turbulent flow and high resistance to clogging.
Very low production variation coefficient assures the highest emission uniformity.

TAPE MODELS:

6 MIL 20 CM 1 L/H	8 MIL 20 CM 1 L/H
6 MIL 30 CM 1 L/H	8 MIL 30 CM 1 L/H
6 MIL 30 CM 1.6 L/H	8 MIL 30 CM 1.6 L/H

APPLICATION: STARDROP tape is designed to be used in open field and in greenhouses for such crops as onion, carrot, reddish, beetroot, maize.

DESCRIPTION

Standard spacing between emitters is from 20cm to 30cm. Wall thickness is from 6 mil to 8 mil. Flow rate per emitter at working pressure 0.7 bar: 1,0 l/h. THE LOWER THE FLOW RATE – THE NARROWER THE LABYRINTH. THE NARROWER THE LABYRINTH – THE BETTER WATER QUALITY IS REQUIRED. ESPECIALLY DESIGNED EMITTER WITH THE FLOW RATE 1.0 L/H. THE EMITTER WITH A WIDER LABYRINTH ENABLES TO INCREASE THE RESISTANCE TO CLOGGING. Flow rate per emitter at working pressure 1 bar: 1,6 l/h.

DRIP TAPE SPECIFICATIONS: Inner diameter 16,1 mm Turbo flat emitter 1,0 l/h
