SD-TAPE
SD-TAPE- innovative drip tape with the most advanced labyrinth design presented in the market: maximum emission uniformity and resistance to clogging. The labyrinth design sets a new standard of clogging resistance:
- 3D emitter inlet ensures resistance to clogging
- Special inlet construction enables emitter productivity even when the emitter itself is covered with a layer of clogging particles
- Special design minimizes penetration of roots and soil particles
Very lower variation coefficient ensures high emission uniformity. Continuous overwhelming quality control assures confidence in excellent results.
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 |
APPLICATION: STARDROP tape is designed to be used in open field and in greenhouses for such crops as onion, carrot, reddish, beetroot, maize.
