1 Introduction
Ridder Growing Solutions supplies both high-tech and simple solutions for large- and
small-scale horticulture companies. Ridder Growing Solutions‘s range is divided into
three product categories:
Water Treatment
Process Automation
Management Systems
The Ridder HortiJet is part of our range of water treatment products and is available
in two models:
HortiJet Pro;
HortiJet-Go!
The difference between these models is in how they are controlled. The HortiJet Pro
offers more advanced options.
This is the installation and user manual for the HortiJet-Go!. This manual was
originally published in Dutch.
1.1 Introduction
The HortiJet-Go! mixes the water with the fertilizers using a bypass from the main
irrigation pipe; this process is automated. This is also known as a 'bypass fertigation
system'.
The features of this system include:
Proven technology for soil-based crops
Compact and economical solution for large-scale irrigation
Robust, vertical pump for an extensive pressure range
Mixing chamber for improved mixing of water and fertilizers
Dosing channels that can handle up to 1000 L/h
Flexible and intuitive controls
One controller for both fertigation and climate
Remote control option
For hydroponics (cultivation on substrate), we recommend the Ridder FertiMiX.
1.2 Aims
This manual has two aims:
1. The manual describes how to install and connect the HortiJet-Go!.
2. This manual describes the functioning of the HortiJet-Go! and how to maintain
it.

2.2 Process description
The HortiJet works as follows:
Fresh water is supplied.
On the main pipe, there is:
an main irrigation pump which supplies water,
a filter for the filtration of the water,
a pressure gauge (both before and after the filter),
a PSV to maintain the pressure at a constant level.
The filter and pressure gauges can also be fitted to the main pipe
between the inlet and the outlet (nos. 6 & 7 in Figure 2-1). This is for
extra mixing of the water and fertilizers.
The following processes can also be carried out on the main pipe:
(optional) pre-blending of different types of water supply based on an EC
measurement,
(optional) flow meter on the main pipe.
To ensure that the water can flow optimally through the HortiJet-Go!, a branch
(with manual valve) is created from the main pipe.
Some of the water from the main pipe flows into the HortiJet-Go! via the inlet.
The pressure in the inlet is reduced by a PRV.
After the PRV, there are EC and pH sensors (optional). The dosage of fertilizers
and acid can be adjusted based on the incoming data from these sensors.
The pressure switch monitors whether the pressure of the water supply is
sufficient.
The fertilizers are supplied to the HortiJet from fertilizer tanks, via supply
hoses.
There are five venturis in the HortiJet. The fertilizers are drawn through these.
There are dosing channels connected to the venturis (maximum of four for
fertilizers, maximum of one for acid). This is where the fertilizers are added.
The supply hoses are connected to the dosing channels.
From the distribution pipe, the water flows through the venturis to the collection
pipe. There is a compensation channel parallel to the venturis. The amount of
water flowing through the compensation channel will depend on the number of
dosing channels connected. There is a PRV in the compensation channel. This is
used to set the pressure difference across the venturis.
The process then goes through the air release valve and the HortiJet pump. The
HortiJet pump sends the water into the mixing chamber where the fertilizers
and water mix.
The water then flows past the PSV to set the pressure at which the water is
pushed back into the main pipe via the outlet. The PRVs and the PSV enable both
the pressure and the flow in the HortiJet to be regulated.
The water that leaves the HortiJet mixes with the water in the main pipe.
Most of the water goes to the irrigation valves and the crop. Some of the water
circulates back to the HortiJet so that the EC and pH levels of the irrigation
water can be measured.
HortiJet-Go!
11

The entire process is regulated by the HortiMaX-Go! process controller. Its tasks
include:
ensuring that the correct fertigation recipe is mixed (proportion of fertilizers
and water).
controlling the valves to ensure that the water reaches the crop.
2.3 Product specifications
The HortiJet-Go! is available in various configurations, because different dosing
channels, pumps, sensors and I/O modules can be added to the HortiJet-Go!. This is
described in the following sections.

* You can calculate the required fertilizer dosing capacity by multiplying the
maximum required irrigation water (main pipe capacity) by the maximum required
fertilizer dosing ratio.
EXAMPLE
With a dosing ratio of up to 10L per fertilizer per m3of irrigation water, the
1000 L/h dosing channels are suitable for irrigation of between 60 and 100
m3/h.
** Acid can also be dosed using a fertilizer dosing channel; the indicated acid
resistance should be taken into account.
*** One HortiJet has between one and four fertilizer dosing channels and, optionally,
one acid dosing channel.
2.3.3 Pumps
The pump type depends on the dosing capacity, the pressure in the main pipe and the
electrical frequency.
2.3.4 Sensors
This section describes the sensors.

Depending on the configuration, the following sensors can be added:
EC sensor: the EC sensor measures the concentration of fertilizers in the water.
pH sensor: the pH sensor measures the acidity level of the water.
You can have zero, one or two sensors of both types. The HortiJet-Go! is supplied
without sensors as standard.
If there is one EC / pH sensor: this is the control sensor.
If two EC / pH sensors are present: the verification sensor checks the
functioning of the control sensor.
On the HortiJet-Go!, the positions of the sensors for the HortiJet Pro are capped.
Please consult the supplied OEM manuals for the correct use and maintenance of the
relevant components.
2.3.5 I/O modules
The HortiJet-Go! uses I/O modules called Smart Switches. Smart Switches are the
(manual control) switches used for the HortiMaX-Go! process controller. These
switches feature an electrical circuit, a processor and software.
The following table below provides an overview of the different types of I/O modules:
Module type When relevant
Smart Switch
Weather/Alarm
Always.
Smart Switch System
pump HortiJet
Always.
Smart Switch EC If fertilizers are dosed based on an EC measurement.
Smart Switch Fertilizer If fertilizers are dosed based on quantity (EC
measurement is optional).
Smart Switch pH If acid is dosed based on a pH measurement.
The 'EC’ and 'Fertilizer’ Smart Switches are also equipped with an input for a
flow meter. Both Smart Switches are available in two versions:
1. Suitable for the signal from a flow sensor (GF15)
2. Suitable for the signal of a water meter (based on pulses)
Other types of Smart Switches are not part of the HortiJet itself, but can be supplied
as accessories.

2.4 Control
The HortiJet-Go! is controlled by an integrated process controller that has its own
operating system, called the HortiMaX-Go!.
2.4.1 HortiMaX-Go!
The HortiMaX-Go! is an affordable, user-friendly control computer designed
specifically for the horticultural sector. With the HortiMaX-Go!, you can control both
the irrigation and the climate inside your greenhouse. The HortiMaX-Go! is easy to
customize by choosing unique Smart Switches that can be installed in a plug-and-play
manner.
The HortiMaX-Go! is also a breeze to operate using its touchscreen display. In
combination with the CloudBox and the HortiMaX-Go! app, you can even operate the
HortiMaX-Go! remotely with your smartphone. You can manage your Cloudboxes,
controllers and app users on our CloudPortal.
