No Drain Drippers: What You Need To Know

Standard Pressure Compensating (PC) drippers provide a consistent flow rate over a wide pressure range to ensure uniformity regardless of run length or elevation.

No Drain (ND) drippers take this further by also sealing when pressure falls below a specified level.

The benefit of ND is that it keeps the pressure in the tube when the dripper is turned off enabling you to pulse irrigate. Without this feature, the system would drain at shut-off and would need to re-fill at each operation and water retribution along the irrigation flow will not be even

Dripper Pegs: Choosing The Correct Option

If you have more than one peg and tube per dripper, it is necessary to use an equalizer DripPeg that also has a flow equalizing labyrinth built in.

This reduces the risk that if one peg is lower than the other, it will expel more water than pegs at higher elevation. Therefore, when using multiple pegs per dripper, you should use DripPeg or Polytif which both have built in flow equalizing labyrinth.

Note: Rivulis DripPeg, Polytif, BarPeg and SnaPeg are designed for Rivulis E1000 and Rivulis Supertif only. Rivulis pegs can be used with Eurodrip Corona drippers by the use of Eurodrip 1, 2 or 4 way adaptors

Rivulis White Drip Line Solutions

Why consider using white drip line in your greenhouse?

White drip line or tube dramatically reduces the water temperature being delivered to the plants. This lower water temperature can significantly benefit crops, particularly young plants where feeder roots are more sensitive to water temperature. In addition, because the water temperature is lower, scaling is reduced, which reduces the risk of dripper clogging, and ultimately increases the lifespan of the drip line. In a field study comparing white drip lines to black drip lines, the water coming out of the white drip line was 10°C lower than the water from the black drip line. Rivulis white tubing is used in greenhouses, climate control and overhead irrigation systems. White tubing is available in 16, 20, and 25 mm. All Rivulis white tubing is produced using multi-layer technology with a black internal tube layer to prevent algae build-up.

Germination & Overhead Irrigation

For greenhouses, even with drip irrigation, an overhead irrigation system including mist sprayers and/or micro sprinklers is often needed for germination, chemigation and sometimes as supplementary irrigation.

Note, you may choose to use overhead irrigation for all of your irrigation requirements; however, this is only suitable for specific crops that are durable to fungus and pests.

 

Mist Sprayers: Rivulis Rondo Mist Sprayer for Fine Seed Germination

If you are growing from fine seeds, it is best to use a mist sprayer in order to protect seeds from large droplets of conventional mini sprinklers.

A mister differs from a micro sprinkler by spreading very fine drops without a spinner.

Each droplet is approximately 150 microns in size, which is distributed in a uniform pattern of 2 meters on average.

The Rivulis Rondo Mist Sprayers deliver 47 to 61 l/h of water (at 3.0 bar pressure).

Micro Sprinklers: Rivulis Rondo – Inverted Application

The Rivulis Rondo Micro Sprinkler is one of the most trusted sprinklers worldwide.

Did you know that the Rivulis Rondo is also available in an inverted model, designed specifically for greenhouse irrigation? Available in a range of flow rates from 30 – 300 l/h (2.0 bar pressure) and two different spinner options (flat and convex), Rivulis Rondo can be customized to irrigate 5.0 – 10.8 meters diameter per sprinkler.

Micro Sprinklers: Rivulis Rondo

 

Convex Trajectory (Green Spinner)

Convex Trajectory green spinner

Provides a larger wetted diameter allowing for larger distance between sprinklers. However if using convex trajectory spinners, you will need to suspend the sprinkler down at least 65 cm to prevent droplets from hitting the greenhouse roof

 

Flat Trajectory (Blue Spinner)

Flat Trajectory Blue Spinner

Water droplets are spread horizontally from the sprinkler head. This enables the sprinkler to be suspended higher while decreasing the diameter of each sprinkler. This is mostly recommended for the greenhouse edges where less wetting of the plastic is required, or shorter wetting diameter is required. Note: Rivulis Rondo PC (RFR) models are only available with flat trajectory spinners.

 

Rivulis RFR: Pressure Compensated (PC) Rondo

The Rivulis RFR model is a reliable inverted model that contains an accurate flow regulating mechanism.

This simply means that a sprinkler receiving 1.5 bar of pressure will emit the same flow as a sprinkler receiving 3.0 bar of pressure. The result is better water distribution uniformity in your greenhouse

 

Climate Control: Humidity & Cooling

Greenhouses are designed to provide a mico-climate providing the optimal temperature needed to accelerate plant growth and provide versatility of crop growth without being restricted by the outside climate or relative humidity. The correct environment is critical for healthy plant growth. This environment can be achieved through the use of foggers that distribute fine water droplets into the air.

When foggers are used, they help increase the humidity in the air while also lowering the overall temperature in the greenhouse. Use foggers to reduce the air temperature and/or to increase the air humidity.

 

Create the Best Environment For Healthy Plant Growth with Foggers

  • The correct environment is critical for healthy plant growth. This environment can be achieved through the use of foggers that distribute fine water droplets into the air.
  • Use foggers to reduce the air temperature and/or to increase the air humidity.

Foggers

 

Installation Considerations

To make sure that plants stay dry during the foggers activity, foggers should be installed in the highest position possible, ideally above the path. By calculating distance x temperature x humidity, it is possible to calculate the falling distance required for drops to evaporate. This helps minimize the risk of plant disease. The efficiency of a cooling system is subject to the relative humidity. The most common configuration for standard applications is 3 x 2 m (4 outlet option), however your Rivulis representative can assist you with calculating the FLF requirements for your greenhouse.

Benefits of Anti-Leak Mini Valves

The primary benefit of anti-leak valves is that they keep the system pressurized at shut-off.

After a shift is complete, the pressure will fall and the anti-leak valve will seal. This enables pulse irrigation because the system does not need to refill.

Another major benefit of anti-leak valves is that water will not drain, which could damage the crop below it.

Rivulis anti-leak valves are suitable for a wide range of Rivulis misters, sprinklers and foggers

Design: Sprinklers, Misters & Foggers

When designing for sprinklers, you are measuring the coefficient of uniformity which is a 3D analysis where you want to achieve minimum 90% uniformity over the total area. This analysis includes the effect of sprinkler overlap.

When designing for drip, you are most commonly designing to minimize flow variation of 10% along each row. Effectively this is a two-dimensional analysis. Our team at the Rivulis Global Design centers have the expertise to help you design the sprinkler system for your greenhouse
