Green house

For many years NaanDanJain has been deeply involved in developing advanced irrigation solutions for greenhouses, nurseries and tunnels.

These are the highlights of our range of products for various applications:

GREENHOUSE & NET HOUSE IRRIGATION TOTAL COVERAGE, OVERLAP CONCEPT

INVERTED SYSTEM

The inverted micro-sprinkler with optional LPD (leakage prevention device) is used for intensive full

irrigation or as a pulsating system for the direct cooling of plants. The LPD allows the immediate opening of the whole section at the same time and the pipes remain full of water between two operations. The surface level is free for cultivation and all other internal activities.

NaanDanJain recommend the following micro sprinklers :

Hadar 7110 -Inverted modal with low pressure LPD

Modular

AquaMaster 2005

Green Spin

TUNNEL IRRIGATION

The inverted irrigation system is commonly recommended to keep the surface level free of obstacles. NaanDanJain has developed a unique concept—the side-byside

Anti-Mist—to achieve the highest uniformity of water distribution in the cultivated area, with minimal wetting of the tunnel walls.

The most suitable product, with optimal components (nozzle and swivel) and installation spacing (number of laterals, distance between micros on the lateral), should be decided on according to tunnel width and crop needs.

PROPAGATION AND ROOTING

The task of supplying controlled moisture and humidity means taking into consideration the various needs of the propagated seed and cutting at various Substrates. Our range of foggers and micro-sprinklers, with various droplet sizes, help maintain the desired conditions in the nursery and the propagated tables:

Hadar 7110 – mist sprayer with low pressure Super LPD bayonet

Modular – flat spreader with low pressure Super LPD

Green mist – with low pressure Super LPD

4 Foggers on cross – with high pressure Super LPD

CLIMATE CONTROL HUMIDITY AND COOLING SYSTEMS

Our Fogger and Super Fogger systems achieve optimal control of humidity and cooling in the greenhouse.

This low-pressure system requires only 3.0/4.0 bar at the fogger inlet. The concept is based on natural air exchange and circulation. (The use of fans for circulation can improve results, but they’re not essential). Temperatures are reduced by up to 100 C on hot, dry days.

WET PAD COOLING SYSTEM WITH AIR SUCTION

This concept is based on air exchange. The external dry air sucked in through a water drop screen. The screen is made of triple layers of net (instead of the original, expensive, wet pad construction). A set of fans mounted on the opposite wall create the air suction. The result is enriched moist air flow through the greenhouse, cooling the growing plants, without the salinity effect. The water distribution system is based on a half-circle (180 degrees) Modular sprayer, with a completely closed circulation of water.

PESTICIDE SPRAY SYSTEM

The pesticide spray system is based on the Fogger cooling system: one system with two tasks. This preventative spray concept is operated by a single person who doesn’t enter the greenhouse and is therefore protected from the pesticides.

The spray takes 1-2 minutes for each valve/section. It facilitates immediate response to newly developed Diseases.

FROST PROTECTION

Frost protection can be achieved by NaanDanJain micro-sprinklers and sprinklers , which are designed to create an ice cover on the greenhouse or tunnel plastic cover. In a net house this works under net, above the plants. The ice formation isolates the greenhouse from the low temperatures outside.

The concept entails continuous operation rather than in pulses. The system can work at temperatures as low as –60C.

A recommended solution is the sprinkler MAKMAD 16 and the micro sprinkler HADAR 7110

DRIP IRRIGATION

Drip irrigation systems ensure high irrigation accuracy and water use efficiency. They also provide a precise solution for fertigation. In many greenhouses the crop is grown in a soilless medium and in small volume receptacles that requires high frequency irrigation. To achieve uniformity in such cases, it is recommended to use CNL (compensating non-leakage) drippers that keep the system full and ensure that all drippers start and stop simultaneously.

NDJ PE DL PIPES

Double-layered, polyethylene pipes for micro sprinkler and button dripper installation.

Featuring a UV-protected white external coating.

Why White?

When working with non-leakage emitters, such as button drippers or micro-sprinklers, the system remains full and the water inside the pipes tends to heat up. Irrigating small plants with hot water can damage the plants.

NaanDanJain’s PE DL PIPES (with a double layer, external white and internal black) reduce water temperature by up to 8˚C, while also ensuring that light doesn’t penetrates and promote algae formation in the pipe. Using light-colored pipes and accessories also allows optimal radiation for photosynthesis.
